According to Osho, Martin Buber remains irreducibly dualistic: his I–Thou relation deepens intimacy but never dissolves the two. Therefore, within Buber’s theistic existentialism, Krishna cannot be accepted as a nondual avatar or the Self; at most, he becomes the supreme 'Thou'—the divine Other to whom the 'I' relates—because Buber’s Jewish roots resist any proclamation of oneness with God.
Buber would see Krishna only as a separate God you relate to, not as your own deepest Self.
