Benefit
A memoir presenting the story of how Brian lost his marbles.
A notable psychiatrist is convinced that his patient has access to past lives via hypnosis. Bonus material: the patient gains access in a between lives state to Masters that communicate wisdom to the good doctor. This is easily one of the most bizarre books that I've read. Published in 1988, I haven't yet looked around to see if it has been exposed as a hoax.
