The Psychedelic Experience: A Manual Based on the Tibetan Book of the Dead Spiral-Bound | June 27, 2017

Timothy Leary was one of the most famous countercultural icons of the 1960s. In 1957, the Harvard psychologist experienced a “profound transcendent experience” while taking hallucinogens in Mexico. No longer content with his work in personality assessment, Leary began advocating the psychotherapeutic and spiritual benefits of LSD. His “experiments” with LSD often involved students and wild “tripping” parties, which eventually led to his dismissal from Harvard. With patronage from heirs of the Mellon fortune, Leary continued his experiments and prolific writing career at an estate in upstate New York known as Millbrook. In 1967, Leary spoke at a San Francisco “Be‑In,” where he coined the phrase “Turn on, tune in, drop out.” Labeled as the “Most Dangerous Man in America,” Leary had many run‑ins with the law and served several prison sentences. He died of prostate cancer in 1996; the following year seven grams of his ashes were launched into space aboard a Pegasus rocket.
         
Ralph Metzner is a professor emeritus of psychology at the California Institute for Integral Studies and president of the Green Earth Foundation, a nonprofit organization dedicated to reconnecting humans and the environment. He is also well known for his decades of research and writing on the subjects of consciousness, psychedelics, the practice of yoga, meditation and shamanism.
 
Richard Alpert, also known as Ram Dass, is a former professor who conducted controversial LSD experiments with Timothy Leary at Harvard and Millbrook. He eventually made a philosophical split from Leary and traveled to India to study Hinduism and yoga. This transformational experience led him to write the classic spiritual text Be Here Now. Having founded a number of spiritual organizations that promote personal growth, the importance of serving others, and unity among different religious traditions, Ram Dass is considered one of the most important spiritual teachers of the 20th century.
