Early Buddhism and Advaita Vedānta — Anātman and Ātman: The Central Debate of Indian Philosophy

Both traditions accept karma, saṃsāra, and liberation as the framework of philosophical inquiry. Both accept that ordinary human life is characterised by suffering and confusion, and that a path exists beyond it. Both see the root of bondage in a form of ignorance about reality.

Both traditions produce strikingly similar descriptions of the liberated state: a falling-away of the sense of being a separate ego-self; an expansion of awareness; a quality of peace that defies ordinary description. Both warn that this cannot be fully conveyed in language.

Early Buddhism: there is no permanent self (anātman). What we call 'I' is a conventional designation for the five aggregates (pañca-skandha) — form, feeling, perception, mental formations, consciousness. Each aggregate is impermanent. None is the self. Their combination is not the self either. Liberating insight is the direct recognition of no-self.

Advaita Vedānta: there is a permanent self (ātman), and it is identical with Brahman — the universal, infinite, self-luminous consciousness. What we call 'I' in ordinary experience is a mixture of true selfhood (ātman) and apparent individuality (ahaṃkāra). Liberating insight is the recognition of ātman as Brahman, not the recognition of no-self.

The sharpest question: is the liberating recognition 'there is no self' or 'I am the universal self'? The experiential descriptions are similar — both involve the collapse of the ordinary ego-sense. But the metaphysical interpretations are opposite.

Śaṅkara's response to Buddhism: if there is no self, who is it that recognises no-self? The recognition itself implies a recogniser. The act of knowing cannot be reduced to the five aggregates — knowing is the witness of the aggregates, not one of them. This witness-consciousness is the ātman.

Buddhism's response: the witness-consciousness Śaṅkara posits would itself be an object of awareness — not the pure subject he claims. Anything that can be introspected is not the ultimate knower. There is only the stream of knowing-events, not a fixed knower behind them.

Early Buddhism: the apparent individual is a conventional designation — no real individual, no real self. The mind-stream continues after death in dependence on karma until liberation (nirvāṇa).

Advaita: the apparent individual is Brahman appearing as a limited consciousness. At liberation, the illusory limitation is removed — not the individual (which was always Brahman) but the superimposition of individuality.

Early Buddhism: nirvāṇa — the extinguishing of the conditions that sustain suffering. Often described as 'the cessation of becoming' — neither existence nor non-existence in ordinary senses.

Advaita: mokṣa — the recognition that individual consciousness was always identical with Brahman. Nothing new is achieved; a false superimposition is removed. Jīvanmukti — liberated while living.

The most honest answer: the debate has not been resolved and cannot be — it depends on the interpretation of experience that neither side can demonstrate to the other's satisfaction. Both traditions produce practitioners who describe liberation similarly. The metaphysical frameworks that account for this liberation are genuinely incompatible. Murti's thesis (that both point at the same inexpressible ultimate) remains a productive hypothesis, not a settled conclusion.
