Ātman (/ˈɑːtmən/), attā or attan in Buddhism is the concept of self, and is found in Buddhist literature's discussion of the concept of non-self (Anatta).

Most Buddhist traditions and texts reject the premise of a permanent, unchanging atman (self, soul).  However, some Buddhist schools, sutras and tantras present the notion of an atman or permanent "Self", although mostly referring to an Absolute and not to a personal self.
