The Supreme Identity: An Essay on Oriental Metaphysic and the Christian Religion

By Alan Watts

Watts sets Vedanta's insight that the deepest self and ultimate reality are one alongside Christian doctrine, asking whether the two can genuinely be reconciled. He treats "the supreme identity" not as a pious metaphor but as a metaphysical claim with real consequences for how we understand God, evil and the self. Denser and more rigorous than his later popular works, and it rewards patient reading.
