Psychedelic drugs, personal freedom and countercultural psychology dominate Timothy Leary’s published work. The Psychedelic Experience, written with Ralph Metzner and Richard Alpert, adapts the Tibetan Book of the Dead into a guide for LSD experiences, while High Priest and Flashbacks recount his role in the American psychedelic movement and the controversies surrounding it.
