Vedānta and Buddhism — The Great Debate on the Self

The shared diagnosis

Both Vedānta and Buddhism agree on the problem with extraordinary precision: ordinary human consciousness is characterised by a deep, pre-reflective misidentification that generates suffering. In Vedānta this is avidyā (ignorance of the true nature of the self); in Buddhism it is avijjā (ignorance of the impermanent, conditioned, non-self nature of all phenomena). Both hold that this ignorance is not merely an intellectual error but a pervasive orientation of the entire psycho-physical system, and that its correction requires sustained practice, not just correct information.

Both agree that liberation is not achieved by acquiring something new but by the removal of what obscures what is already the case. And both teach that meditative investigation — turning awareness toward its own nature — is a central element of that removal.

The foundational disagreement: ātman or anātman?

For Advaita Vedānta, the deepest nature of the experiencer is ātman — pure, unchanging, self-luminous awareness, identical with Brahman, the ground of all being. The Upaniṣadic declaration aham brahmāsmi (I am Brahman) is the recognition of this identity. Liberation is the full, stable recognition that this has always been the case.

For Buddhism, the investigation of experience reveals the opposite: there is no fixed, permanent, self-sufficient self to be found anywhere in experience. What presents itself as a unified self is a flowing stream of interdependent processes. The Buddha deliberately declined to answer whether a self exists or not after death ("Is the self the same after death or different?" — avyākata, undeclared) — not because the question is unimportant but because it is malformed: it presupposes a fixed entity where there is none.

Śaṅkara's charge: Buddhism without the self is the same as Advaita

Śaṅkara made a famous and pointed charge in his Brahma Sūtra Bhāṣya: the Vijñānavāda (consciousness-only) school of Mahāyāna Buddhism (Yogācāra) is "crypto-Vedānta" (pracchanna-bauddha) in disguise — it posits a universal consciousness (ālaya-vijñāna) that plays the same structural role as Brahman. The Buddhist response, particularly from the Madhyamaka school, is that śūnyatā (emptiness) applies equally to any putative universal consciousness — including the Vedāntic Brahman. Neither school is simply right about the other's position, but the exchange pushed both to greater precision.

The convergence that neither school entirely denies

Contemporary study finds striking structural parallels between Advaita and Madhyamaka despite their doctrinal incompatibility. Both hold that the ordinary sense of a fixed, independently existing self is the root delusion. Both warn that conceptual understanding of their own doctrines, however sophisticated, is not liberation. Both use negation (neti neti in Advaita; the tetralemma in Nāgārjuna) to guard against reifying their own teachings. Both locate liberation in a recognition that is immediate and non-conceptual. The question of whether the awareness that remains after the self's deconstruction is "pure consciousness" (Advaita) or "empty of inherent existence" (Madhyamaka) may be, as some contemporary philosophers suggest, a difference of emphasis rather than a difference in what is actually pointed at.
