Samadhi

From Wikipedia, the free encyclopedia

Samādhi (Sanskrit: समाधि, Hindi pronunciation: [səˈmaːdʱi]), also called samāpatti, in Buddhism, Hinduism, Jainism, Sikhism and yogic schools refers to a state of meditative consciousness. In the Yogic traditions, and the Buddhist commentarial tradition on which the Burmese Vipassana movement and the Thai Forest traditon rely, it is a meditative absorption or trance, attained by the practice of dhyāna. In the oldest Buddhist suttas, on which several contemporary western Theravada teachers rely, it refers to the development of a luminous mind which is equanimous and mindful.

In Buddhism, it is the last of the eight elements of the Noble Eightfold Path. In the Ashtanga Yoga tradition, it is the eighth and final limb identified in the Yoga Sutras of Patanjali.

Definitions

  • Sarbacker: samādhi is meditative absorption, attained by the practice of dhyāna.
  • Diener, Erhard & Fischer-Schreiber: samādhi is a non-dualistic state of consciousness in which the consciousness of the experiencing subject becomes one with the experienced object.
  • Shankman: an abiding in which mind becomes very still but does not merge with the object of attention, and is thus able to observe and gain insight into the changing flow of experience.
  • Paramahansa Yogananda: A soundless state of breathlessness. A blissful super consciousness state in which a yogi perceives the identity of the individualized Soul and Cosmic Spirit.

Etymology

Sanskrit

Various interpretations for the term's etymology are possible:
  • sam, "together"; a, "toward"; stem of dadhati, "puts, places": "a putting or joining together;"
  • sam, "together" or "integrated"; ā, "towards"; dhā, "to get, to hold": "to acquire integration or wholeness, or truth";
  • sam, "uniformly" or "fully"; adhi, "to get established: : a state wherein one establishes himself to the fullest extent in the Supreme consciousness;
  • samā, "even"; dhi, "intellect": a state of total equilibrium of a detached intellect;
  • sam, "perfect," "complete." dhi, "consciousness": a state of being where "all distinctions between the person who is the subjective meditator, the act of meditation and the object of meditation merge into oneness";
  • sama, "equanimous" dhi,"buddhi or the intellect."

Chinese

Common Chinese terms for samādhi include the transliterations sanmei (三昧) and sanmodi (三摩地 or 三摩提), as well as the translation of the term literally as ding (定 "fixity"). Kumarajiva's translations typically use sanmei (三昧), while the translations of Xuanzang tend to use ding (定 "fixity"). The Chinese Buddhist canon includes these as well as other translations and transliterations of the term.

Origins

According to Rhys Davids the first attested usage of the term samadhi in Sanskrit literature was in the Maitri Upanishad.

The origins of the practice of dhyana, which culminates into samadhi, are a matter of dispute. According to Bronkhorst, dhyana was a Buddhist invention, whereas Alexander Wynne argues that dhyana was incorporated from Brahmanical practices, in the Nikayas ascribed to Alara Kalama and Uddaka Ramaputta. These practices were paired to mindfulness and insight, and given a new interpretation. Kalupahana also argues that the Buddha "reverted to the meditational practices" he had learned from Alara Kalama and Uddaka Ramaputta.

Buddhism

Samadhi

The term 'Samadhi' derives from the root sam-a-dha, which means 'to collect' or 'bring together', and thus it is often translated as 'concentration' or 'unification of mind'. In the early Buddhist texts, samadhi is also associated with the term samatha (calm abiding). In the commentarial tradition, samadhi is defined as ekaggata, one-pointedness of mind (Cittass'ekaggatā).

Buddhagosa defines samadhi as "the centering of consciousness and consciousness concomitants evenly and rightly on a single object [...] the state in virtue of which consciousness and its concomitants remain evenly and rightly on a single object, undistracted and unscattered." According to Buddhaghosa, the Theravada Pali texts mention four kinds of samadhi:
  • Momentary concentration (khanikasamadhi): A mental stabilization which arises during vipassana;
  • Preliminary concentration (parikammasamadhi): Arises out of the meditator's initial attempts to focus on a meditation object;
  • Access concentration (upacarasamadhi): Arises when the five hindrances are dispelled, when jhana is present, and with the appearance the 'counterpart sign' (patibhaganimitta);
  • Absorption concentration (appanasamadhi): The total immersion of the mind on its meditation of object and stabilization of all four jhanas.

Samadhi and dhyana

Samadhi is the last of the eight elements of the Noble Eightfold Path. It is often interpreted as referring to dhyana, but in the suttas samadhi and dhyana are not the same. While samadhi is one-pointed concentration, in dhyana this samadhi is used in the initial stages, to give way to a state of equanimity and mindfulness. The practice of dhyana makes it possible to keep access to the senses in a mindful way, avoiding primary responses to the sense-impressions.

Qualities of the rupa jhānas



The Suttapitaka and the Agamas describe four stages of rupa jhāna. Rupa refers to the material realm, in a neutral stance, as different form the kama realm (lust, desire) and the arupa-realm (non-material realm). Each jhāna is characterised by a set of qualities which are present in that jhana:
  • First dhyāna: the first dhyana can be entered when one is secluded from sensuality and unskillful qualities. There is pīti ("rapture") and non-sensual sukha ("pleasure") as the result of seclusion, while vitarka-vicara ("discursive thought") continues;
  • Second dhyana: there is pīti ("rapture") and non-sensual sukha ("pleasure") as the result of concentration (samadhi-ji, "born of samadhi"); ekaggata (unification of awareness) free from vitarka-vicara ("discursive thought"); inner tranquility;
  • Third dhyana: upekkhā (equanimous; "affective detachment"), mindful, and alert, and senses pleasure with the body;
  • Fourth dhyana: upekkhāsatipārisuddhi (purity of equanimity and mindfulness); neither-pleasure-nor-pain. Traditionally, the fourth jhāna is seen as the beginning of attaining psychic powers (abhijñā).

Interpretation of the four dhyanas

According to Richard Gombrich, the sequence of the four rupa-jhanas describes two different cognitive states:
I know this is controversial, but it seems to me that the third and fourth jhanas are thus quite unlike the second.
Alexander Wynne further explains that the dhyana-scheme is poorly understood. According to Wynne, words expressing the inculcation of awareness, such as sati, sampajāno, and upekkhā, are mistranslated or understood as particular factors of meditative states, whereas they refer to a particular way of perceiving the sense objects:
Thus the expression sato sampajāno in the third jhāna must denote a state of awareness different from the meditative absorption of the second jhāna (cetaso ekodibhāva). It suggests that the subject is doing something different from remaining in a meditative state, i.e. that he has come out of his absorption and is now once again aware of objects. The same is true of the word upek(k)hā: it does not denote an abstract 'equanimity', [but] it means to be aware of something and indifferent to it [...] The third and fourth jhāna-s, as it seems to me, describe the process of directing states of meditative absorption towards the mindful awareness of objects.
The Noble Eightfold Path is a condensation of more elaborate descriptions of this path, which starts with a householder who hears the dhamma and leaves home (either literally or figuratively), and after preparatory practices starts with the practice of dhyana. The Pāli canon describes eight progressive states of jhāna: four meditations of form (rūpa jhāna), and four formless meditations (arūpajhānas), though the early texts do not use the term dhyana for the four formless meditations, calling them instead āyatana (dimension, sphere, base). A ninth form is Nirodha-Samāpatti.

According to Bronkhorst, the four rūpa jhāna may be an original contribution of the Buddha to the religious landscape of India. They formed an alternative to the painful ascetic practices of the Jains. The arūpa jhāna were incorporated from non-Buddhist ascetic traditions. According to Crangle, the development of meditative practices in ancient India was a complex interplay between Vedic and non-Vedic traditions.

Dhyana and insight

A core problem in the study of early Buddhism is the relation between dhyana and insight. The Buddhist tradition has incorporated two traditions regarding the use of jhana. There is a tradition that stresses attaining insight (bodhi, prajna, kensho) as the means to awakening and liberation. But it has also incorporated the yogic tradition, as reflected in the use of jhana, which is rejected in other sutras as not resulting in the final result of liberation. The problem was famously voiced in 1936 by Louis de La Vallee Poussin, in his text Musila et Narada: Le Chemin de Nirvana.

Schmithausen discerns three possible roads to liberation as described in the suttas, to which Vetter adds the sole practice of dhyana itself, which he sees as the original "liberating practice":
  • The four Rupa Jhanas themselves constituted the core liberating practice of early buddhism, c.q. the Buddha;
  • Mastering the four Rupa Jhanas, where-after "liberating insight" is attained;
  • Mastering the four Rupa Jhanas and the four Arupa Jhanas, where-after "liberating insight" is attained;
  • Liberating insight itself suffices.
This problem has been elaborated by several well-known scholars, including Tilman Vetter, Johannes Bronkhorst, and Richard Gombrich. Schmithausen notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36. Both Schmithausen and Bronkhorst note that the attainment of insight, which is a cognitive activity, cannot be possible in state wherein all cognitive activity has ceased. According to Vetter and Bronkhorst, dhyana itself constituted the original "liberating practice". According to Alexander Wynne, the ultimate aim of dhyana was the attainment of insight, and the application of the meditative state to the practice of mindfulness. According to Frauwallner, mindfulness was a means to prevent the arising of craving, which resulted simply from contact between the senses and their objects. According to Frauwallner, this may have been the Buddha's original idea. According to Wynne, this stress on mindfulness may have led to the intellectualism which favoured insight over the practice of dhyana.

The arupas

Grouped into the jhana-scheme are four meditative states, referred to in the early texts as aruppas. These are also referred to in commentarial literature as immaterial/formless jhānas (arūpajhānas), also translated as The Formless Dimensions, in distinction from the first four jhānas (rūpa jhānas). In the Buddhist canonical texts, the word "jhāna" is never explicitly used to denote them, they are instead referred to as āyatana. However, they are sometimes mentioned in sequence after the first four jhānas (other texts. e.g. MN 121 treat them as a distinct set of attainments) and thus came to be treated by later exegetes as jhānas. The immaterial are related to, or derived from, yogic meditation, and aim more specific at concentration, while the jhanas proper are related to the cultivation of the mind. The state of complete dwelling in emptiness is reached when the eighth jhāna is transcended.

The four arupas are:
  • fifth jhāna: infinite space (Pali ākāsānañcāyatana, Skt. ākāśānantyāyatana);
  • sixth jhāna: infinite consciousness (Pali viññāṇañcāyatana, Skt. vijñānānantyāyatana);
  • seventh jhāna: infinite nothingness (Pali ākiñcaññāyatana, Skt. ākiṃcanyāyatana);
  • eighth jhāna: neither perception nor non-perception (Pali nevasaññānāsaññāyatana, Skt. naivasaṃjñānāsaṃjñāyatana).
Although the "Dimension of Nothingness" and the "Dimension of Neither Perception nor Non-Perception" are included in the list of nine Jhanas taught by the Buddha, they are not included in the Noble Eightfold Path. Noble Path number eight is "Samma Samadhi" (Right Concentration), and only the first four Jhanas are considered "Right Concentration". If he takes a disciple through all the Jhanas, the emphasis is on the "Cessation of Feelings and Perceptions" rather than stopping short at the "Dimension of Neither Perception nor Non-Perception".

In Buddhist tradition

Theravada

According to Buddhaghosa, in his influential standard-work Visuddhimagga, samadhi is the "proximate cause" to the obtainment of wisdom. The Visuddhimagga describes 40 different objects for meditation, which are mentioned throughout the Pali canon, but explicitly enumerated in the Visuddhimagga, such as mindfulness of breathing (anapanasati) and loving kindness (metta).

Several western teachers (Thanissaro Bhikkhu, Leigh Brazington, Richard Shankman) make a distinction between 'sutta-oriented' jhana' and 'Visuddhimagga-oriented' jhana. Thanissaro Bhikkhu has repeatedly argued that the Pali Canon and the Visuddhimagga give different descriptions of the jhanas, regarding the Visuddhimagga-descriotion to be incorrect. Keren Arbel has conducted extensive research on the jhanas and the contemporary criticisms of the commentarial interpretation. Based on this research, and her own experience as a senior meditation-teacher, she gives a reconstructed account of the original meaning of the dhyanas. She argues that jhana is an integrated practice, describing the fourth jhana as "lucid awareness," not as a state of deep concentration.

Mahayana

Indian Mahayana
The earliest extant Indian Mahayana texts emphasize ascetic practices and forest dwelling, and absorption in states of meditative oneness. These practices seem to have occupied a central place in early Mahayana, also because they "may have given access to fresh revelations and inspiration."

In the Indian Mahayana traditions the term is also to refer to forms of "samadhi" other than dhyana. Section 21 of the Mahavyutpatti records even 118 samadhi. The Samadhiraja Sutra for example has as its main theme a samādhi called 'the samadhi that is manifested as the sameness of the essential nature of all dharmas' (sarva-dharma-svabhavā-samatā-vipañcita-samādhi).
Zen

Indian dhyana was translated as chán in Chinese, and zen in Japanese. Ideologically the Zen-tradition emphasizes prajna and sudden insight, but in the actual practice prajna and samādhi, or sudden insight and gradual cultivation, are paired to each other. Especially some lineages in the Rinzai school of Zen stress sudden insight, while the Sōtō school of Zen lays more emphasis on shikantaza, training awareness of the stream of thoughts, allowing them to arise and pass away without interference.

Hinduism

Patanjali's Yoga sutras

Samadhi is the main subject of the eighth limb of the Yoga Sutras called Samadhi-pada. They resemble the Buddhist jhanas. According to David Gordon White, the language of the Yoga Sutras is often closer to "Buddhist Hybrid Sanskrit, the Sanskrit of the early Mahayana Buddhist scriptures, than to the classical Sanskrit of other Hindu scriptures." According to Karel Werner,
Patanjali's system is unthinkable without Buddhism. As far as its terminology goes there is much in the Yoga Sutras that reminds us of Buddhist formulations from the Pāli Canon and even more so from the Sarvastivada Abhidharma and from Sautrāntika."
Robert Thurman writes that Patañjali was influenced by the success of the Buddhist monastic system to formulate his own matrix for the version of thought he considered orthodox. However, it is also to be noted that the Yoga Sutra, especially the fourth segment of Kaivalya Pada, contains several polemical verses critical of Buddhism, particularly the Vijñānavāda school of Vasubandhu.

Samadhi

Samadhi is oneness with the object of meditation. There is no distinction between act of meditation and the object of meditation. Samadhi is of two kinds, with and without support of an object of meditation:
  • Samprajnata Samadhi, also called savikalpa samadhi and Sabija Samadhi, meditation with support of an object;

    Samprajata samadhi is associated with deliberation, reflection, bliss, and I-am-ness;
The first two, deliberation and reflection, form the basis of the various types of samapatti:

  • Savitarka, "deliberative": The citta is concentrated upon a gross object of meditation, an object with a manifest appearance that is perceptible to our senses, such as a flame of a lamp, the tip of the nose, or the image of a deity. Conceptualization (vikalpa) still takes place, in the form of perception, the word and the knowledge of the object of meditation. When the deliberation is ended this is called nirvitaka samadhi;
  • Savichara, "reflective": the citta is concentrated upon a subtle object of meditation, which is not perceptible to the senses, but arrived at through inference, such as the senses, the process of cognition, the mind, the I-am-ness, the chakras, the inner-breath (prana), the nadis, the intellect (buddhi). The stilling of reflection is called nirvichara samapatti.
The last two associations, sananda samadhi and sasmita, are respectively a state of meditation, and an object of savichara samadhi:

  • Sananda Samadhi, ananda, "bliss": this state emphasizes the still subtler state of bliss in meditation;
  • Sasmita: the citta is concentrated upon the sense or feeling of "I-am-ness".
  • Asamprajnata Samadhi, also called Nirvikalpa Samadhi and Nirbija Samadhi: meditation without an object, which leads to knowledge of purusha or consciousness, the subtlest element.

Ananda and asmita

According to Ian Whicher, the status of sananda and sasmita in Patanjali's system is a matter of dispute. According to Maehle, the first two constituents, deliberation and reflection, form the basis of the various types of samapatti. According to Feuerstein,
"Joy" and "I-am-ness" [...] must be regarded as accompanying phenomena of every coginitive [ecstacy]. The explanations of the classical commentators on this point appear to be foreign to Patanjali's hierarchy of [ecstatic] states, and it seems unlikely that ananda and asmita should constitute independent levels of samadhi.
Ian Whicher disagrees with Feuerstein, seeing ananda and asmita as later stages of nirvicara-samapatti. Whicher refers to Vācaspati Miśra (900-980 CE), the founder of the Bhāmatī Advaita Vedanta who proposes eight types of samapatti:
  • Savitarka-samāpatti and Nirvitarka-samāpatti, both with gross objects as objects of support;
  • Savicāra-samāpatti and Nirvicāra-samāpatti, both with subtle objects as objects of support;
  • Sānanda-samāpatti and Nirānanda-samāpatti, both with the sense organs as objects of support;
  • Sāsmitā-samāpatti and Nirasmitā-samāpatti, both with the sense of "I-am-ness" as support.
Vijnana Bikshu (ca. 1550-1600) proposes a six-stage model, explicitly rejecting Vacaspati Misra's model. Vijnana Bikshu regards joy (ananda) as a state that arises when the mind passes beyond the vicara stage. Whicher agrees that ananda is not a separate stage of samadhi. According to Whicher, Patanjali's own view seems to be that nirvicara-samadhi is the highest form of cognitive ecstasy.

Samyama

According to Taimni, dharana, dhyana and samadhi form a graded series:
  • Dharana. In dharana, the mind learns to focus on a single object of thought. The object of focus is called a pratyaya. In dharana, the yogi learns to prevent other thoughts from intruding on focusing awareness on the pratyaya;
  • Dhyana. Over time and with practice, the yogin learns to sustain awareness of only the pratyaya, thereby dharana transforms into dhyana. In dhyana, the yogin comes to realize the triplicity of perceiver (the yogin), perceived (the pratyaya) and the act of perceiving. The new element added to the practice of dhyana, that distinguish it from dharana is the yogi learns to minimize the perceiver element of this triplicity. In this fashion, dhyana is the gradual minimization of the perceiver, or the fusion of the observer with the observed (the pratyaya);
  • Samadhi. When the yogin can: (1) sustain focus on the pratyaya for an extended period of time, and (2) minimize his or her self-consciousness during the practice, then dhyana transforms into samadhi. In this fashion then, the yogin becomes fused with the pratyaya. Patanjali compares this to placing a transparent jewel on a colored surface: the jewel takes on the color of the surface. Similarly, in samadhi, the consciousness of the yogin fuses with the object of thought, the pratyaya. The pratyaya is like the colored surface, and the yogin's consciousness is like the transparent jewel.

Sahaja samadhi

Ramana Maharshi distinguished between kevala nirvikalpa samadhi and sahaja nirvikalpa samadhi:
Sahaja samadhi is a state in which a silent level within the subject is maintained along with (simultaneously with) the full use of the human faculties.
Kevala nirvikalpa samadhi is temporary, whereas sahaja nirvikalpa samadhi is a continuous state throughout daily activity. This state seems inherently more complex than sāmadhi, since it involves several aspects of life, namely external activity, internal quietude, and the relation between them. It also seems to be a more advanced state, since it comes after the mastering of samadhi.

Sahaja is one of the four keywords of the Nath sampradaya along with Svecchachara, Sama, and Samarasa. Sahaja meditation and worship was prevalent in Tantric traditions common to Hinduism and Buddhism in Bengal as early as the 8th–9th centuries.

Sikhism

The Samadhi of Ranjit Singh is located next to the iconic Badshahi Masjid in Lahore, Pakistan.

In Sikhism the word is used to refer to an action that one uses to remember and fix one's mind and soul on Waheguru.[citation needed] The Sri Guru Granth Sahib informs:
  • "Remember in meditation the Almighty Lord, every moment and every instant; meditate on God in the celestial peace of Samādhi." (p. 508);
  • "I am attached to God in celestial Samādhi." (p. 865);
  • "The most worthy Samādhi is to keep the consciousness stable and focused on Him." (p. 932).
The term Samadhi refers to a state of mind rather than a physical position of the body. The Scriptures explain:
  • "I am absorbed in celestial Samādhi, lovingly attached to the Lord forever. I live by singing the Glorious Praises of the Lord" (p. 1232);
  • "Night and day, they ravish and enjoy the Lord within their hearts; they are intuitively absorbed in Samadhi. ||2||" (p. 1259).
The Sikh Gurus inform their followers:
  • "Some remain absorbed in Samādhi, their minds fixed lovingly on the One Lord; they reflect only on the Word of the Shabad." (p. 503).

In the oldest texts of Buddhism, Dhyāna (Sanskrit) or Jhāna (Pali) is a series of cultivated states of mind, commonly translated as meditation, which lead to a "state of perfect equanimity and awareness (upekkhii-sati-piirisuddhl)." Dhyana may have been the core practice of pre-sectarian Buddhism, together with several preceding practices which lead to calm and detachment, and are fully realized with th practice of dhyana.

In the later commentarial tradition, which has survived in present-day Theravada, dhyana is equated with "concentration," a state of one-pointed absorption in which there is a diminished awareness of the surroundings. In the contemporary Theravada-based Vipassana-movement, this absorbed state of mind is regarded as unnecessary and even non-beneficial for awakening, which has to be reached by mindfullness of the body and vipassana (insight into impermanence). Since the 1980s, scholars and practitioners have started to question this equation, arguing for a more comprehensive and integrated understanding and approach, based on the oldest descriptions of dhyana in the suttas.

In Chan and Zen, the Chinese and Japanese renderings of dhyana, dhyana is the central practice, which is ultimately based on Sarvastivada meditation practices, and has been transmitted since the beginning of the Common Era.

Etymology

Dhayana is commonly translated as meditation, and is often equated with "concentration," though meditation may refer to a wider scala of exercises for bhavana, development. Dhyana can also mean "attention, thought, reflction." According to Buddhaghosa, the term "jhana" (Skt. dhyana) is derived from the verb jhayati, "to think or meditate," while the verb jhapeti, "to burn up," explicates its function, namely burning-up opposing states, burning-up or destroying "the mental defilements preventing [...] the development of serenity and insight."

The jhānas

The Pāli canon describes four progressive states of jhāna called rūpa jhāna ("form jhana"), and four additional meditative states called arūpa ("without form").

Preparatory practices

Meditation and contemplation are preceded by preparatory practices, which are fully realized with the practice of dhyana. As described in the Noble Eightfold Path, right view leads to leaving the household life and becoming a wandering monk. Sila (morality) comprises the rules for right conduct. Right effort, c.q. the four right efforts, aim to prevent the arising of unwholesome states, and to generate wholesome states. This includes indriya samvara (sense restraint), controlling the response to sensual perceptions, not giving in to lust and aversion but simply noticing the objects of perception as they appear. Right effort and mindfulness calm the mind-body complex, releasing unwholesome states and habitual patterns, and encouraging the development of wholesome states and non-automatic responses. By following these cumulative steps and practices, the mind becomes set, almost naturally, for the practice of dhyana. The practice of dhyana reinforces the development of wholesome states, leading to upekkha (equanimity) and mindfulness.

The rupa jhānas

Qualities of the rupa jhānas



The practice of dhyana is aided by anapanasati, mindfulness of breathing. The Suttapitaka and the Agamas describe four stages of rupa jhāna. Rupa refers to the material realm, in a neutral stance, as different form the kama realm (lust, desire) and the arupa-realm (non-material realm). Each jhāna is characterised by a set of qualities which are present in that jhana:
  • First dhyāna: the first dhyana can be entered when one is secluded from sensuality and unskillful qualities. There is pīti ("rapture") and non-sensual sukha ("pleasure") as the result of seclusion, while vitarka-vicara ("discursive thought") continues;
  • Second dhyana: there is pīti ("rapture") and non-sensual sukha ("pleasure") as the result of concentration (samadhi-ji, "born of samadhi"); ekaggata (unification of awareness) free from vitarka-vicara ("discursive thought"); sampasadana ("inner tranquility");
  • Third dhyana: upekkhā (equanimous; "affective detachment"), mindful, and alert, and senses pleasure with the body;
  • Fourth dhyana: upekkhāsatipārisuddhi (purity of equanimity and mindfulness); neither-pleasure-nor-pain. Traditionally, the fourth jhāna is seen as the beginning of attaining psychic powers (abhijñā).

Interpretation of the four dhyanas

While the jhana's are often understood as deepening states of concentration, due to its description as such in the Abhidhamma, and the Visuddhimagga, since the 1980s scholars and modern Theravadins have started to question this understanding.

Roderick S. Bucknell notes that vitarka and vicara may refer to "probably nothing other than the normal process of discursive thought, the familiar but usually unnoticed stream of mental imagery and verbalization." Bucknell further nothes that "[t]hese conclusions conflict with the widespread conception of the first jhana as a state of deep concentration."

According to Stuart-Fox, the Abhidhamma separated vitarka from vicara, and ekagatta (onepointednes) was added to the description first dhyana to give an equal number of five hindrances and five anti-dotes. The commentarial tradition regards the qulities of the first dhyana to be antidotes to the five hindrances, and ekagatta may have been added to the first dhyana to give exactly five anti-dotes for the five hindrances. Stuart-Fox further notes that vitarka, being discursive thought, will do very little as an anti-dote for sloth and torpor, reflecting the inconsistencies which were introduced by the scholastics.

Vetter, Gombrich and Wynne note that the first and second jhana represent the onset of dhyana due to withdrawal and right effort c.q. the four right efforts, followed by concentration, whereas the third and fourth jhana combine concentration with mindfulness. Polak, elaborating on Vetter, notes that the onset of the first dhyana is described as a quite natural process, due to the preceding efforts to restrain the senses and the nurturing of wholesome states. Regarding samadhi as the eight step of the Noble Eightfold Path, Vetter notes that samadhi consists of the four stages of dhyana meditation, but
...to put it more accurately, the first dhyana seems to provide, after some time, a state of strong concentration, from which the other stages come forth; the second stage is called samadhija" [...] "born from samadhi."
According to Richard Gombrich, the sequence of the four rupa-jhanas describes two different cognitive states: "I know this is controversial, but it seems to me that the third and fourth jhanas are thus quite unlike the second." Gombrich and Wynne note that, while the second jhana denotes a state of absorption, in the third and fourth jhana one comes out of this absorption, being mindfully awareness of objects while being indifferent to it. According to Gombrich, "the later tradition has falsified the jhana by classifying them as the quintessence of the concentrated, calming kind of meditation, ignoring the other – and indeed higher – element.

Gethin, followed by Polak and Arbel, further notes that there is a "definite affinity" between the four jhanas and the bojjhaṅgā, the seven factors of awakening. According to Gethin, the early Buddhist texts have "a broadly consistent vision" regarding meditation practice. Various practices lead to the development of the factors of awakening, which are not only the means to, but also the constituents of awakening. According to Gethin, satipatthana and anapanasati are related to a formula that summarizes the Buddhist path to awakening as "abandoning the hindrances, establishing [...] mindfulness, and developing the seven factors of awakening." "This results in a "heightened awareness," "overcoming distracting and disturbing emotions," which are not particular elements of the path to awakening, but rather common disturbing and distracting emotions. Gethin further states that "the exegetical literature is essentially true to the vision of meditation presented in the Nikayas," applying the "perfect mindfulness, stillness and lucidity" of the jhanas to the contemplation of "reality," of the way things really are, as temporary and ever-changing. It is in this sense that "the jhana state has the transcendent, transforming quality of awakening."

Upekkhā, equanimity, which is perfected in the fourth dhyana, is one of the four Brahma-vihara. While the commentarial tradition downplayed the importance of the Brahma-vihara, Gombrich notes that the Buddhist usage of the brahma-vihāra originally referred to an awakened state of mind, and a concrete attitude toward other beings which was equal to "living with Brahman" here and now. The later tradition took those descriptions too literally, linking them to cosmology and understanding them as "living with Brahman" by rebirth in the Brahma-world. According to Gombrich, "the Buddha taught that kindness - what Christians tend to call love - was a way to salvation.

Alexander Wynne states that the dhyana-scheme is poorly understood. According to Wynne, words expressing the inculcation of awareness, such as sati, sampajāno, and upekkhā, are mistranslated or understood as particular factors of meditative states, whereas they refer to a particular way of perceiving the sense objects:
Thus the expression sato sampajāno in the third jhāna must denote a state of awareness different from the meditative absorption of the second jhāna (cetaso ekodibhāva). It suggests that the subject is doing something different from remaining in a meditative state, i.e. that he has come out of his absorption and is now once again aware of objects. The same is true of the word upek(k)hā: it does not denote an abstract 'equanimity', [but] it means to be aware of something and indifferent to it [...] The third and fourth jhāna-s, as it seems to me, describe the process of directing states of meditative absorption towards the mindful awareness of objects.
Thanissaro Bhikkhu, a western teacher in the Thai Forest Tradition, argues that the Visuddhimagga deviates from the Pali Canon in its description of the jhanas, and warns against the development of strong states of concentration. Arbel describes the fourth jhana as "non-reactive and lucid awareness," not as astate of deep concentration.

The arupas

Grouped into the jhana-scheme are four meditative states, referred to in the early texts as aruppas. These are also referred to in commentarial literature as immaterial/formless jhānas (arūpajhānas), also translated as The Formless Dimensions, in distinction from the first four jhānas (rūpa jhānas). In the Buddhist canonical texts, the word "jhāna" is never explicitly used to denote them, they are instead referred to as āyatana. However, they are sometimes mentioned in sequence after the first four jhānas (other texts. e.g. MN 121 treat them as a distinct set of attainments) and thus came to be treated by later exegetes as jhānas. The immaterial are related to, or derived from, yogic meditation, while the jhanas proper are related to the cultivation of the mind. The state of complete dwelling in emptiness is reached when the eighth jhāna is transcended.

The four arupas are:
  • fifth jhāna: infinite space (Pali ākāsānañcāyatana, Skt. ākāśānantyāyatana),
  • sixth jhāna: infinite consciousness (Pali viññāṇañcāyatana, Skt. vijñānānantyāyatana),
  • seventh jhāna: infinite nothingness (Pali ākiñcaññāyatana, Skt. ākiṃcanyāyatana),
  • eighth jhāna: neither perception nor non-perception (Pali nevasaññānāsaññāyatana, Skt. naivasaṃjñānāsaṃjñāyatana).
Although the "Dimension of Nothingness" and the "Dimension of Neither Perception nor Non-Perception" are included in the list of nine Jhanas taught by the Buddha, they are not included in the Noble Eightfold Path. Noble Path number eight is "Samma Samadhi" (Right Concentration), and only the first four Jhanas are considered "Right Concentration". If he takes a disciple through all the Jhanas, the emphasis is on the "Cessation of Feelings and Perceptions" rather than stopping short at the "Dimension of Neither Perception nor Non-Perception".

Nirodha-Samapatti

Beyond the dimension of neither perception nor non-perception lies a state called Nirodha Samapatti, the "cessation of perception, feelings and consciousness". Only in commentarial and scholarly literature this sometimes is called the "ninth jhāna".

Origins

The time of the Buddha saw the rise of the śramaṇa movement, ascetic practitioners with a body of shared teachings and practices. The strict delineation of this movement into Jainism, Buddhism and brahmanical/Upanishadic traditions is a later development.

Invention or incorporation

According to Bronkhorst, the practice of the four dhyanas may have been an original contribution by Gautama Buddha to the religious practices of ancient India in response to the ascetic practices of the Jains. Kalupahana argues that the Buddha "reverted to the meditational practices" he had learned from Ārāḍa Kālāma and Uddaka Rāmaputta. Wynne argues that Ārāḍa Kālāma and Uddaka Rāmaputta were Brahmanical teachers, and that the attainment of the formless meditative absorption was incorporated from Brahmanical practices. These practices were paired to mindfulness and insight, and given a new interpretation. The stratification of particular samādhi experiences into the four jhānas seems to be a Buddhist innovation. It was then borrowed and presented in an incomplete form in the Mokṣadharma, a part of the Mahābhārata.

Thomas William Rhys Davids and Maurice Walshe agreed that the term samadhi is not found in any pre-Buddhist text but is first mentioned in the Tipiṭaka. It was later incorporated into later texts such as the Maitrayaniya Upanishad. But according to Matsumoto, "the terms dhyana and samahita (entering samadhi) appear already in Upanishadic texts that predate the origins of Buddhism".

Buddhist origins

The Mahasaccaka Sutta, Majjhima Nikaya 36, narrates the story of the Buddha's awakening. According to this story, he learned two kinds of meditation, which did not lead to enlightenment. He then underwent harsh ascetic practices with which he eventually also became disillusioned. The Buddha then recalled a meditative state he entered by chance as a child:
I thought: 'I recall once, when my father the Sakyan was working, and I was sitting in the cool shade of a rose-apple tree, then — quite secluded from sensuality, secluded from unskillful mental qualities — I entered & remained in the first jhana: rapture & pleasure born from seclusion, accompanied by directed thought & evaluation. Could that be the path to Awakening?' Then following on that memory came the realization: 'That is the path to Awakening.'
Originally the practice of dhyana itself may have constituted the core liberating practice of early Buddhism, since in this state all "pleasure and pain" had waned. According to Vetter,
[P]robably the word "immortality" (a-mata) was used by the Buddha for the first interpretation of this experience and not the term cessation of suffering that belongs to the four noble truths [...] the Buddha did not achieve the experience of salvation by discerning the four noble truths and/or other data. But his experience must have been of such a nature that it could bear the interpretation "achieving immortality".

Brahmanical influences

Alexander Wynne attempted to find parallels in Brahmanical texts to the meditative goals the two teachers claimed to have taught, drawing especially on some of the Upanishads and the Mokshadharma chapter of the Mahabharata.

Uddaka Ramaputta and Alara Kalama

The suttas describe how the Buddha learned meditative practices from two teachers, Uddaka Ramaputta and Alara Kalama. Alex Wynne argues that Uddaka Ramaputta belonged to the pre-Buddhist tradition portrayed by the Buddhist and Brahmanic sources, in which the philosophical formulations of the early Upanishads were accepted, and the meditative state of "neither perception nor non-perception" was equated with the self. Wynne further argues that the goal of Alara Kalama was a Brahminical concept. Evidence in the Chandogya Upanishad and the Taittiriya Upanishad suggests that a different early Brahminic philosophical tradition held the view that the unmanifest state of Brahman was a form of non-existence. According to Wynne it thus seems likely that both element and formless meditation was learned by the Buddha from his two teachers, and adapted by him to his own system.

Brahmanical practices

Formless spheres
It appears that in early Brahminic yoga, the formless spheres were attained following element meditation. This is also taught as an option in the early Buddhist texts. The primary method taught to achieve the formless attainment in early Buddhist scriptures, on the other hand, is to proceed to the sphere of infinite space following the fourth jhāna.
Reversal of the creation of the world
Wynne claimed that Brahminic passages on meditation suggest that the most basic presupposition of early Brahmanical yoga is that the creation of the world must be reversed, through a series of meditative states, by the yogin who seeks the realization of the self. These states were given doctrinal background in early Brahminic cosmologies, which classified the world into successively coarser strata. One such stratification is found at TU II.1 and Mbh XII.195, and proceeds as follows: self, space, wind, fire, water, earth. Mbh XII.224 gives alternatively: Brahman, mind, space, wind, fire, water, earth.

In Brahmanical thought, the meditative states of consciousness were thought to be identical to the subtle strata of the cosmos. There is no similar theoretical background to element meditation in the early Buddhist texts, where the elements appear simply as suitable objects of meditation. It is likely that the Brahmanic practices of element-meditation were borrowed and adapted by early Buddhists, with the original Brahmanic ideology of the practices being discarded in the process.
Investigation of self
On this point, it is thought that the uses of the elements in early Buddhist literature have in general very little connection to Brahmanical thought; in most places they occur in teachings where they form the objects of a detailed contemplation of the human being. The aim of these contemplations seems to have been to bring about the correct understanding that the various perceived aspects of a human being, when taken together, nevertheless do not comprise a 'self'. Moreover, the self is conceptualized in terms similar to both "nothingness" and "neither perception nor non-perception" at different places in early Upanishadic literature.

The latter corresponds to Yajnavalkya’s definition of the self in his famous dialogue with Maitreyi in the Brihadaranyaka Upanishad and the definition given in the post-Buddhist Mandukya Upanishad. This is mentioned as a claim of non-Buddhist ascetics and Brahmins in the Pañcattaya Sutta (Majjhima Nikaya 102.2). In the same dialogue in the Brihadaranyaka Upanishad, Yajnavalkya draws the conclusions that the self that is neither perceptive nor non-perceptive is a state of consciousness without object. The early Buddhist evidence suggests much the same thing for the state of "neither perception nor non-perception". It is a state without an object of awareness, that is not devoid of awareness. The state following it in the Buddhist scheme, the "cessation of perception and sensation", is devoid not only of objectivity, but of subjectivity as well.

Criticism of Wynne

The Brahmanical texts cited by Wynne assumed their final form long after the Buddha's lifetime. The Mokshadharma postdates him.

Early Buddhism

The Buddhist tradition has incorporated two traditions regarding the use of jhana. There is a tradition that stresses attaining insight (bodhi, prajna, kensho) as the means to awakening and liberation. But the Buddhist tradition has also incorporated the yogic tradition, as reflected in the use of jhana, which is rejected in other sutras as not resulting in the final result of liberation. One solution to this contradiction is the conjunctive use of vipassana and samatha.

Five possibilities regarding jhana and liberation

Schmithausen notes that the mention of the four noble truths as constituting "liberating insight", which is attained after mastering the Rupa Jhanas, is a later addition to texts such as Majjhima Nikaya 36. Schmithausen discerns three possible roads to liberation as described in the suttas, to which Vetter adds a fourth possibility, while the attainment of Nirodha-Samapatti may constitute a fifth possibility:
  • Mastering the four jhanas, where-after "liberating insight" is attained;
  • Mastering the four jhanas and the four arupas, where-after "liberating insight" is attained;
  • Liberating insight itself suffices;
  • The four jhanas themselves constituted the core liberating practice of early Buddhism, c.q. the Buddha;
  • Liberation is attained in Nirodha-Samapatti.

Rupa jhana followed by liberating insight

According to the Theravada-tradition, the meditator uses the jhāna state to bring the mind to rest, and to strengthen and sharpen the mind, in order to investigate the true nature of phenomena (dhamma) and to gain insight into impermanence, suffering and not-self. According to the Theravada-tradition, the arahant is aware that the jhanas are ultimately unsatisfactory, realizing that the meditative attainments are also anicca, impermanent.

In the Mahasaccaka Sutta (Majjhima Nikaya 36), which narrates the story of the Buddha's awakening, dhyana is followed by insight into the four noble truths. The mention of the four noble truths as constituting "liberating insight" is probably a later addition. Vetter notes that such insight is not possible in a state of dhyana, when interpreted as concentration, since discursive thinking is eliminated in such a state. He also notes that the emphasis on "liberating insight" developed only after the four noble truths were introduced as an expression of what this "liberating insight" constituted. In time, other expressions took over this function, such as pratītyasamutpāda and the emptiness of the self.

Rupa jhana and the arupas, followed by liberating insight

This scheme is rejected by scholars as a later development, since the arupas are akin to non-Buddhist practices, and rejected alsewhere in the canon.

Insight alone suffices

The emphasis on "liberating insight" alone seems to be a later development, in response to developments in Indian religious thought, which saw "liberating insight" as essential to liberation. This may also have been due to an over-literal interpretation by later scholastics of the terminology used by the Buddha, and to the problems involved with the practice of dhyana, and the need to develop an easier method.

Contemporary scholars have discerned a broader application of jhana in historical Buddhist practice. According to Alexander Wynne, the ultimate aim of dhyana was the attainment of insight, and the application of the meditative state to the practice of mindfulness. According to Frauwallner, mindfulness was a means to prevent the arising of craving, which resulted simply from contact between the senses and their objects. According to Frauwallner, this may have been the Buddha's original idea. According to Wynne, this stress on mindfulness may have led to the intellectualism which favoured insight over the practice of dhyana.

Jhana itself is liberating

Both Schmithausen and Bronkhorst note that the attainment of insight, which is a cognitive activity, can't be possible in a state wherein all cognitive acitivy has ceased. According to Vetter, the practice of Rupa Jhana itself may have constituted the core practice of early Buddhism, with practices such as sila and mindfulness aiding to its development. It is the "middle way" between self-mortification, ascribed by Bronkhorst to Jainism, and indulgence in sensual pleasure. Vetter emphasizes that dhyana is a form of non-sensual happiness. The eightfold path can be seen as a path of preparation which leads to the practice of samadhi.

Liberation in Nirodha-Samapatti

According to some texts, after progressing through the eight jhanas and the stage of Nirodha-Samapatti, a person is liberated. According to some traditions someone attaining the state of Nirodha-Samapatti is an anagami or an arahant. In the Anupadda sutra, the Buddha narrates that Sariputta became an arahant upon reaching it.

Theravada

Dhyana as concentration

Buddhagosa's Visuddhimagga considers jhana to be an exercise in concentration-meditation. His views, together with the Satipatthana Sutta, inspired the development, in the 19th and 20th century, of new meditation techniques which gained a great popularity among lay audiences in the second half of the 20th century.

Samadhi

According to Henepola Gunaratana, the term "jhana" is closely connected with "samadhi", which is generally rendered as "concentration". The word "samadhi" is almost interchangeable with the word "samatha", serenity. According to Gunaratana, in the widest sense the word samadhi is being used for the practices which lead to the development of serenity. In this sense, samadhi and jhana are close in meaning. Nevertheless, they are not exactly identical, since "certain differences in their suggested and contextual meanings prevent unqualified identification of the two terms." Samadhi signifies only one mental factor, namely one-pointedness, while the word "jhana" encompasses the whole state of consciousness, "or at least the whole group of mental factors individuating that meditative state as a jhana." Furthermore, according to Gunaratana, samadhi involves "a wider range of reference than jhana," noting that "the Pali exegetical tradition recognizes three levels of samadhi: preliminary concentration (parikammasamadhi) [...] access concentration (upacarasamadhi) [...] and absorption concentration (appanasamadhi)."

Development and application of concentration

According to the Pāli canon commentary, access/neighbourhood concentration (upacāra-samādhi) is a stage of meditation that the meditator reaches before entering into jhāna. The overcoming of the five hindrances mark the entry into access concentration. Access concentration is not mentioned in the discourses of the Buddha, but there are several suttas where a person gains insight into the Dhamma on hearing a teaching from the Buddha.

According to Tse-fu Kuan, at the state of access concentration, some meditators may experience vivid mental imagery, which is similar to a vivid dream. They are as vivid as if seen by the eye, but in this case the meditator is fully aware and conscious that they are seeing mental images. According to Tse-fu Kuan, this is discussed in the early texts, and expanded upon in Theravāda commentaries.

According to Venerable Sujivo, as the concentration becomes stronger, the feelings of breathing and of having a physical body will completely disappear, leaving only pure awareness. At this stage inexperienced meditators may become afraid, thinking that they are going to die if they continue the concentration, because the feeling of breathing and the feeling of having a physical body has completely disappeared. They should not be so afraid and should continue their concentration in order to reach "full concentration" (jhāna).

A meditator should first master the lower jhānas, before they can go into the higher jhānas. According to Nathan Katz, the early suttas state that "the most exquisite of recluses" is able to attain any of the jhānas and abide in them without difficulty.

According to the contemporary Vipassana-movement, the jhāna state cannot by itself lead to enlightenment as it only suppresses the defilements. Meditators must use the jhāna state as an instrument for developing wisdom by cultivating insight, and use it to penetrate the true nature of phenomena through direct cognition, which will lead to cutting off the defilements and nibbana.

According to the later Theravāda commentorial tradition as outlined by Buddhagoṣa in his Visuddhimagga, after coming out of the state of jhāna the meditator will be in the state of post-jhāna access concentration. In this state the investigation and analysis of the true nature of phenomena begins, which leads to insight into the characteristics of impermanence, suffering and not-self arises.

Contemporary reassessment - the "Jhana wars"

While Theravada-meditation was introduced to the west as vipassana-meditation, which rejected the usefulness of jhana, there is a growing interest among western vipassana-practitioners in jhana. The nature and practice of jhana is a topic of debate and contentment among western convert Theravadins, to the extent that the disputes have even been called "the Jhana wars." Both academic scholars and contemporary practitioners have raised questions about the interpretation of the jhanas as being states of absorption which are not necessary for the attainment of liberation. While groundbreaking research on this topic has been done by Bareau, Schmithausen, Stuart-Fox, Bucknell, Vetter, Bronkhorst, and Wynne, Theravada practitioners have also scrutinized and criticised the samatha-vipassana distinction. Reassessments of the description of jhana in the suttas consider jhana and vipassana to be an integrated practice, leading to a "tranquil and eqaunimous awareness of whatever arises in the field of experience."

Criticism of Visudhimagga

The Visuddhimagga, and the "pioneering popularizing work of Daniel Goleman," has been influential in the (mis)understanding of dhyana being a form of concentration-meditation. The Visuddhimagga is centered around kasina-meditation, a form of concentration-meditation in which the mind is focused on a (mental) object. According to Thanissaro Bhikkhu, "[t]he text then tries to fit all other meditation methods into the mold of kasina practice, so that they too give rise to countersigns, but even by its own admission, breath meditation does not fit well into the mold." According to Thanissaro Bhikkhu, "the Visuddhimagga uses a very different paradigm for concentration from what you find in the Canon." In its emphasis on kasina-meditation, the Visuddhimagga departs from the Pali Canon, in which dhyana is the central meditative practice, indicating that what "jhana means in the commentaries is something quite different from what it means in the Canon."

Bhante Henepola Gunaratana also notes that what "the suttas say is not the same as what the Visuddhimagga says [...] they are actually different," leading to a divergence between a [traditional] scholarly understanding and a practical understanding based on meditative experience. Gunaratana further notes that Buddhaghosa invented several key meditation terms which are not to be found in the suttas, such as "parikamma samadhi (preparatory concentration), upacara samadhi (access concentration), appanasamadhi (absorption concentration)." Gunaratana also notes that the Buddhaghosa's emphasis on kasina-meditation is not to be found in the suttas, where dhyana is always combined with mindfulness.

According to Vetter, dhyana as a preparation of discriminating insight must have been different from the dhyana-practice introduced by the Buddha, using kasina-exercises to produce a "more artificially produced dhyana", resulting in the cessation of apperceptions and feelings. Kasina-exercises are propagated in Buddhaghosas Visuddhimagga, which is considered the authoritative commentary on meditation practice in the Theravada tradition, but differs from the Pali canon in its description of jhana. While the suttas connect samadhi to mindfulness and awareness of the body, for Buddhaghosa jhana is a purely mental exercise, in which one-pointed concentration leads to a narrowing of attention.

Jhana as integrated practice

Several western teachers (Thanissaro Bhikkhu, Leigh Brazington, Richard Shankman) make a distinction between 'sutta-oriented' jhana' and 'Visuddhimagga-oriented' jhana, dubbed "minimalists" and "maimalists" by Kenneth Rose.

Thanissaro Bhikkhu has repeatedly argued that the Pali Canon and the Visuddhimagga give different descriptions of the jhanas, regarding the Visuddhimagga-descriotion to be incorrect.

According to Richard Shankman, the sutta descriptions of jhāna practice explain that the meditator does not emerge from jhāna to practice vipassana but rather the work of insight is done whilst in jhāna itself. In particular the meditator is instructed to "enter and remain in the fourth jhāna" before commencing the work of insight in order to uproot the mental defilements.

Keren Arbel has conducted extensive research on the jhanas and the contemporary criticisms of the commentarial interpretation. Based on this research, and her own experience as a senior meditation-teacher, she gives a reconstructed account of the original meaning of the dhyanas. She argues that jhana is an integrated practice, describing the fourth jhana as "non-reactive and lucid awareness," not as a state of deep concentration. According to Arbel, it develops "a mind which is not conditioned by habitual reaction-patterns of likes and dislikes [...] a profoundly wise relation to experience, not tainted by any kind of wrong perception and mental reactivity rooted in craving (tanha).

According to Kenneth Rose, the Visuddhimagga-oriented "maximalist" approach is a return to ancient Indian "mainstream practices," in which physical and mental immobiluty was thought to lead to liberation from samsara and rebirth. This approach was rejected by the Buddha, turning to a gentler approach which results in upekkha and sati, equanimous awareness of experience.

In Mahāyāna traditions

Mahāyāna Buddhism includes numerous schools of practice. Each draw upon various Buddhist sūtras, philosophical treatises, and commentaries, and each has its own emphasis, mode of expression, and philosophical outlook. Accordingly, each school has its own meditation methods for the purpose of developing samādhi and prajñā, with the goal of ultimately attaining enlightenment.

Chan Buddhism

Dhyāna is a central aspect of Buddhist practice in Chan, necessary for progress on the path and "true entry into the Dharma."

Origins

In China, the word dhyāna was originally transliterated with Chinese: 禪那; pinyin: chánnà and shortened to just pinyin: chán in common usage. The word and the practice of meditation entered into Chinese through the translations of An Shigao (fl. c. 148–180 CE), and Kumārajīva (334–413 CE), who translated Dhyāna sutras, which were influential early meditation texts mostly based on the Yogacara meditation teachings of the Sarvāstivāda school of Kashmir circa 1st-4th centuries CE. The word chán became the designation for Chan Buddhism (Korean Seon, Zen).

While dhyana in a strict sense refers to the four dhyanas, in Chinese Buddhism dhyāna may refer to various kinds of meditation techniques and their preparatory practices, which are necessary to practice dhyana. The five main types of meditation in the Dyana sutras are anapanasati (mindfulness of breathing); paṭikūlamanasikāra meditation, mindfulness of the impurities of the body; loving-kindness maitrī meditation; the contemplation on the twelve links of pratītyasamutpāda; and the contemplation on the Buddha’s thirty-two Characteristics.

Mindfulness

Observing the breath
Venerable Hsuan Hua meditating in the Lotus Position. Hong Kong, 1953

During sitting meditation, practitioners usually assume a position such as the lotus position, half-lotus, Burmese, or yoga postures, using the dhyāna mudrā. To regulate the mind, awareness is directed towards counting or watching the breath or by bringing that awareness to the energy center below the navel (see also ānāpānasati). Often, a square or round cushion placed on a padded mat is used to sit on; in some other cases, a chair may be used. This practice may simply be called sitting dhyāna, which is zuòchán (坐禅) in Chinese, and zazen (坐禅) in Japanese, jwaseon (坐禅) in Korean.
Observing the mind
In the Sōtō school of Zen, meditation with no objects, anchors, or content, is the primary form of practice. The meditator strives to be aware of the stream of thoughts, allowing them to arise and pass away without interference. Considerable textual, philosophical, and phenomenological justification of this practice can be found throughout Dōgen's Shōbōgenzō, as for example in the "Principles of Zazen" and the "Universally Recommended Instructions for Zazen". In the Japanese language, this practice is called Shikantaza.

Insight

Pointing to the nature of the mind
According to Charles Luk, in the earliest traditions of Chán, there was no fixed method or formula for teaching meditation, and all instructions were simply heuristic methods, to point to the true nature of the mind, also known as Buddha-nature. According to Luk, this method is referred to as the "Mind Dharma", and exemplified in the story of Śākyamuni Buddha holding up a flower silently, and Mahākāśyapa smiling as he understood. A traditional formula of this is, "Chán points directly to the human mind, to enable people to see their true nature and become buddhas."
Kōan practice
Chinese character for "nothing" (Hanyu Pinyin: ; Japanese pronunciation: mu; Korean pronunciation: mu). It figures in the famous Zhaozhou's dog kōan

At the beginning of the Sòng dynasty, practice with the kōan method became popular, whereas others practiced "silent illumination." This became the source of some differences in practice between the Línjì and Cáodòng schools.

A kōan, literally "public case", is a story or dialogue, describing an interaction between a Zen master and a student. These anecdotes give a demonstration of the master's insight. Koans emphasize the non-conceptional insight that the Buddhist teachings are pointing to. Koans can be used to provoke the "great doubt", and test a student's progress in Zen practice.

Kōan-inquiry may be practiced during zazen (sitting meditation), kinhin (walking meditation), and throughout all the activities of daily life. Kōan practice is particularly emphasized by the Japanese Rinzai school, but it also occurs in other schools or branches of Zen depending on the teaching line.

The Zen student's mastery of a given kōan is presented to the teacher in a private interview (referred to in Japanese as dokusan (独参), daisan (代参), or sanzen (参禅)). While there is no unique answer to a kōan, practitioners are expected to demonstrate their understanding of the kōan and of Zen through their responses. The teacher may approve or disapprove of the answer and guide the student in the right direction. The interaction with a Zen teacher is central in Zen, but makes Zen practice also vulnerable to misunderstanding and exploitation.

Vajrayāna

B. Alan Wallace holds that modern Tibetan Buddhism lacks emphasis on achieving levels of concentration higher than access concentration. According to Wallace, one possible explanation for this situation is that virtually all Tibetan Buddhist meditators seek to become enlightened through the use of tantric practices. These require the presence of sense desire and passion in one's consciousness, but jhāna effectively inhibits these phenomena.

While few Tibetan Buddhists, either inside or outside Tibet, devote themselves to the practice of concentration, Tibetan Buddhist literature does provide extensive instructions on it, and great Tibetan meditators of earlier times stressed its importance.

Related concepts in Indian religions

Dhyana is an important ancient practice mentioned in the Vedic and post-Vedic literature of Hinduism, as well as early texts of Jainism. Dhyana in Buddhism influenced these practices as well as was influenced by them, likely in its origins and its later development.

Parallels with Patanjali's Ashtanga Yoga

There are parallels with the fourth to eighth stages of Patanjali's Ashtanga Yoga, as mentioned in his classical work, Yoga Sutras of Patanjali, which were compiled around 400 CE by, taking materials about yoga from older traditions.

Patanjali discerns bahiranga (external) aspects of yoga namely, yama, niyama, asana, pranayama, and the antaranga (internal) yoga. Having actualized the pratyahara stage, a practitioner is able to effectively engage into the practice of Samyama. At the stage of pratyahara, the consciousness of the individual is internalized in order that the sensations from the senses of taste, touch, sight, hearing and smell don't reach their respective centers in the brain and takes the sadhaka (practitioner) to next stages of Yoga, namely Dharana (concentration), Dhyana (meditation), and Samadhi (mystical absorption), being the aim of all Yogic practices.

The Eight Limbs of the yoga sutras show Samadhi as one of its limbs. The Eight limbs of the Yoga Sutra was influenced by Buddhism. Vyasa's Yogabhashya, the commentary to the Yogasutras, and Vacaspati Misra's subcommentary state directly that the samadhi techniques are directly borrowed from the Buddhists' Jhana, with the addition of the mystical and divine interpretations of mental absorption. However, it is also to be noted that the Yoga Sutra, especially the fourth segment of Kaivalya Pada, contains several polemical verses critical of Buddhism, particularly the Vijñānavāda school of Vasubandhu.

The suttas show that during the time of the Buddha, Nigantha Nataputta, the Jain leader, did not even believe that it is possible to enter a state where the thoughts and examination stop.

Scientific studies

There has been little scientific study of these mental states. In 2008, an EEG study found "strong, significant, and consistent differences in specific brain regions when the meditator is in a jhana state compared to normal resting consciousness". Tentative hypotheses on the neurological correlates have been proposed, but lack supporting evidence.
