The Psychedelic Experience is an instruction manual intended for use during sessions involving psychedelic drugs. Started as early as 1962 in Zihuatanejo, the book was finally published in August 1964. The Psychedelic Experience was authored by Timothy Leary, Ralph Metzner and Richard Alpert, all of whom took part in experiments investigating the therapeutic and spiritual possibilities of drugs such as mescaline, psilocybin and LSD.
The book is dedicated to Aldous Huxley and includes a short introductory citation from Huxley’s book The Doors of Perception. Part of this text was used by The Beatles in their song Tomorrow Never Knows.
The audiobook is extremely interesting and scientifically-approved listening nonetheless.
