"Writing clearly, in the fashion of an investigative reporter, Mike Crowley unlocks the mystery of amrita, and answers, with previously unseen certainty, the question of whether or not psychedelics were part of historical Buddhist practice."
-- Allan Badiner, co-editor of Zig Zag Zen

"Mike Crowley has manifested a delightful book on a topic rarely spoken of, and certainly never explored with such depth. With a combination of personal anecdotes, detailed historical research, and a large collection of traditional art, this book will encourage modern-day Buddhist yogis and mind-explorers to see their practice and its roots in a new way."
-- Rev. Kokyo Henkel, Head Teacher, Santa Cruz Zen Center

"Psychedelic drugs in ancient Buddhism? Believe it. Don't believe it? Read this book."
-- Clark Heinrich, author of Magic Mushrooms in Relgion and Alchemy
