Searching for the Philosophers’ Stone: Encounters with Mystics, Scientists, and Healers

A deeply personal account of the scientific, shamanic, and metaphysical encounters that led to the development of Metzner’s psychological methods • Recounts the author’s meetings and friendships with Albert Hofmann, Alexander Shulgin, the McKenna brothers, Wilson Van Dusen, Myron Stolaroff, and Leo Zeff • Details his lucid dream encounters with G. I. Gurdjieff, profoundly healing sessions with Hawaiian healer Morrnah Simeona, experiences with plant teachers iboga and ayahuasca, and ecological and mystical lessons learned from animal teachers • Shares his involvement in the beginnings of the therapeutic use of MDMA and how it safely and effectively supports the healing of trauma, PTSD, and interpersonal relationships Just as the search for the philosopher’s stone is the core symbol of the alchemical tradition, Ralph Metzner, Ph.D., psychotherapist and one of the respected elders of the psychedelic research community, sees it as the central metaphor of his life-long quest to find methods of healing and insight through heightened states of consciousness.
