Press the one question on both: the ego falls away; what remains?

Vedānta answers: a Self remains. Strip off the ahaṃkāra and the changing inner instruments and you do not arrive at nothing. You arrive at the witness, sākṣin, pure awareness, which is ātman, which is Brahman, infinite and unchanging, your real identity. The self-project ends in a deeper, truer Self.

Buddhism answers: no self remains to be found. Strip off the aggregates and you find only more aggregates, and then their ceasing. There is no witness-Self hiding behind consciousness, because consciousness too is on the list of what is not-self. The self-project ends not in a truer Self but in the release of the search for one, and that release is liberation.

This is not a subtle difference of emphasis. It is the exact point at which one tradition's deepest claim is the other's named error. The Vedāntic sākṣin, unchanging self-luminous awareness held to be one's true identity, is precisely what the Anattalakkhaṇa Sutta appears built to deny when it places viññāṇa among the not-self. So the gentle, near-universal-sounding teaching, "you are the awareness behind your thoughts, rest as that," is not a neutral meeting-ground of all traditions. It is a Vedāntic answer. Buddhism heard that answer, understood it, and declined it. To present "you are the witness" as the shared destination of East and West, as so much popular spirituality does, is to quietly hand the victory to one side while claiming to honor both. The honest thing is to say plainly: here the maps point in different directions.

And the traditions knew it, and argued it for more than a thousand years, each diagnosing the other's characteristic error:

From the Buddhist side, the ātman-as-witness looks like the conceit "I am" reasserting itself at the highest possible altitude. Having rightly let go of the body, the emotions, and the ego, the Vedāntin, in the Buddhist reading, lost nerve at the last step and clutched awareness itself as a permanent self, an eternalist refuge, the very kind of grasping the path is meant to dissolve.

From the Vedānta side, anattā taken strictly looks as if it cannot account for what no one can doubt: the bare awareness presupposed by the very meditation that observes the aggregates arising and passing. Who, Śaṅkara presses, is aware of the flux? To deny the self, he argues, you must presuppose a self doing the denying; the self is self-evident, the one thing that cannot be coherently rejected, and a teaching of pure no-self drifts toward the annihilationism the Buddha himself refused.

Each, in other words, accuses the other of stopping in the wrong place: the Buddhist thinks the Vedāntin halted one step too soon and enshrined awareness as a self; the Vedāntin thinks the Buddhist, having rightly emptied everything else, denied the undeniable light by which the emptying is even seen.
