anātman; nairātmya; no ego, no soul (of an independent and self-contained character), impersonal, no individual independent existence (of conscious or unconscious beings, anātmaka). The empirical ego is merely an aggregation of various elements, and with their disintegration it ceases to exist; therefore it has nm ultimate reality of its own, but the Nirvāṇa Sūtra asserts the reality of the ego in the transcendental realm. The non-Buddhist definition of ego is that it has permanent individuality 常一之體 and is independent or sovereign 有主宰之用. When applied to men it is 人我, when to things it is 法我. Cf. 常 11.

１．無有實我。２．忘卻自己。

陳義孝編, 竺摩法師鑑定, 《佛學常見辭彙》

The lack of existence of an inherent self, soul, or ego, usually translated into English as "no-self" (Skt. anātman, Pali anattā, Tib. bdag me byuṅ). This is one of the most important philosophical concepts in all of Buddhism, and is recorded as having been one of the primary realizations attained by Śākyamuni in his enlightenment experience.
