In Buddhism, the term anattā ( Pali) or anātman ( Sanskrit) refers to the doctrine of "non-self", that there is no unchanging, permanent soul in living beings. It is one of the seven beneficial perceptions in Buddhism, and along with Dukkha (suffering) and Anicca (impermanence), it is one of three Right Understandings about the three marks of existence.

The concept of Anatta or Anatman in Buddhism, is a major difference from the Hindu concept of Atman (self, soul).
