Modern organized religion is based predominantly on secondary religious experience--we read about others' extraordinary spiritual encounters with God but have no direct experience ourselves. Yet there exist powerful sacraments to help us directly experience the sacred, to help us seek out the meaning of being human and our place in the universe, and to help us see the sacred in the world that surrounds us.

In this book, more than 25 spiritual leaders, scientists, and psychedelic visionaries examine how we can return to the primary spiritual encounters at the basis of all religions through the guided use of psychedelics. With contributions by Albert Hofmann, Huston Smith, Stanislav Grof, Charles Tart, Alexander "Sasha" Shulgin, Brother David Steindl-Rast, Myron Stolaroff, and many others, this book explores protocols for ceremonial and spiritual use of psychedelics, including LSD, psilocybin, ayahuasca, and MDMA, and the challenges of transforming entheogenic insights into enduring change. It examines psychoactive sacraments in the Bible, myths surrounding the use of LSD, and the transformative ayahuasca rituals of Santo Daime. The book also includes personal accounts of Walter Pahnke's Good Friday Experiment as well as a 25-year follow-up with its participants.

Dispelling fears of inauthentic spirituality, addiction, and ill-prepared encounters with the holy, this book reveals the potential of psychedelics as catalysts for spiritual development, a path through which faith can directly encounter God's power, and the beginning of a new religious era based on personal spiritual experience.
