The Fool Who Thought He Was God by Genpo Roshi (PDF version)

A mysterious package discovered behind a wall in an abandoned building recounts the strange tale of twin brothers reunited after years apart.  A school teacher’s quiet life is suddenly upended when he discovers his brother Sebastian, who thinks he is God, has had himself committed to a mental institution in Bangor Maine, close to where he himself has been living for years.  He records his visits with his long lost twin and the conversations that leave him increasingly baffled, inspired, and finally uncertain about the thin line between sanity and madness.
