Two chairs
Buddhism teaches there's no fixed self to find, only a stream of shifting parts. Advaita Vedanta says something is still there, watching. Both traditions call seeing it liberation.
The Buddhist teaching of anatta holds that no fixed, unchanging self exists — only five ever-changing aggregates, arising and passing. Advaita Vedanta holds instead that a silent witness, the Atman, is always present beneath every changing state. Both call seeing this clearly the way out of suffering. Which is actually there?
What's checkable: the anatta teaching, Hume's bundle, Advaita's Atman, and the sutta where the Buddha stays silent when asked about a self (SN 44.10), later telling Ananda either answer would mislead. What isn't: which chair is right.
