The secretive Mysteries conducted at Eleusis in Greece for nearly two millennia have long puzzled scholars with strange accounts of initiates experiencing otherworldly journeys. In this groundbreaking work, three experts - a mycologist, a chemist, and a historian - argue persuasively that the sacred potion given to participants in the course of the ritual contained a psychoactive entheogen. The authors then expand the discussion to show that natural psychedelic agents have been used in spiritual rituals across history and cultures.

Exploring the latest developments in the flourishing field of modern psychedelic psychotherapy, this book shares practical experiences and insights from both elders and newer research voices in the psychedelic research and clinical communities.

A groundbreaking dive into the role psychedelics have played in the origins of Western civilization, and the real-life quest for the Holy Grail that could shake the Church to its foundations.

We are in the midst of a powerful psychedelic renaissance. After four decades of hibernation, the promise of the psychoactive 60s - that deeper self-awareness, achieved through reality-bending substances and practices, will lead to greater external harmony - is again gaining a major following. The signs are everywhere, from the influence of today's preeminent psychedelic thinker Daniel Pinchbeck, to the renewed interest in the legacy of Terence McKenna, and to the upsurge of collective cultural phenomena like the spectacle of Burning Man.

Journey alongside professor Bache as he touches the living intelligence of our universe - an intelligence that both embraced and crushed him - and demonstrates how direct experience of the divine can change your perspective on core issues in philosophy and religion. Chronicling his 73 sessions, the author reveals the spiral of death and rebirth that took him through the collective unconscious into the creative intelligence of the universe.

From 1990 to 1995 Dr. Rick Strassman conducted U.S. Government-approved and funded clinical research at the University of New Mexico in which he injected 60 volunteers with DMT, one of the most powerful psychedelics known. His detailed account of those sessions is an extraordinarily riveting inquiry into the nature of the human mind and the therapeutic potential of psychedelics. DMT, a plant-derived chemical found in the psychedelic Amazon brew, ayahuasca, is also manufactured by the human brain. In Strassman's volunteers, it consistently produced near-death and mystical experiences.

This mesmerizing, surreal account of the bizarre adventures of Terence McKenna, his brother Dennis, and a small band of their friends, is a wild ride of exotic experience and scientific inquiry. Exploring the Amazon Basin in search of mythical shamanic hallucinogens, they encounter a host of unusual characters - including a mushroom, a flying saucer, pirate Mantids from outer space, an appearance by James and Nora Joyce in the guise of poultry, and translinguistic matter - and discover the missing link in the development of human consciousness and language.

Less than fifty thousand years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers.

Western medicine has not been particularly successful at getting people relief from conditions like depression, chronic pain, migraine headaches, addiction, and PTSD. Dr. Tafur helps us to understand why. Too often, the Western medical approach fails to address the emotional dimension of illness. This is where traditional plant medicines, with their ability to alter consciousness and open channels of communication to our emotions, offer so much promise.

Called “America’s wisest and most respected authority on psychedelics and their use,” James Fadiman has been involved with psychedelic research since the 1960s. In this guide to the immediate and long-term effects of psychedelic use for spiritual (high dose), therapeutic (moderate dose), and problem-solving (low dose and microdose) purposes, Fadiman outlines best practices for safe, sacred entheogenic voyages learned through his more than 40 years of experience.
