Psyche Unbound: Essays in Honor of Stanislav Grof is an extraordinary compilation of 22 essays that honor the path-breaking lifework of Stanislav Grof, M.D., Ph.D., the world’s leading researcher in psychedelic-assisted therapy, breathwork, and the exploration of non-ordinary states of consciousness. Psyche Unbound features contributions from thought leaders of the last five decades, including a piece from Joseph Campbell’s 1971 lecture in the Great Hall at Cooper Union and Huston Smith’s 1976 summary of Grof’s work as it relates to the study of religion and mysticism. More recent writing includes reflections by renowned psychiatrists and researchers that discuss the importance of Grof’s contributions on the current wave of interest and research into psychedelic-assisted therapies and alternative states of consciousness. Psyche Unbound, considered a festschrift for Stanislav Grof, includes essays that explore Grof’s work on numerous fronts including transpersonal sexual experiences, implications for social and cultural change, comparative studies with Asianreligious systems, the perinatal dimensions of Jean-Paul Sartre’s transformational 1935 mescaline experience, and parallel findings from quantum and relativistic physics. Edited by Richard Tarnas, Ph.D., and Sean Kelly, Ph.D., Psyche Unbound also features contributions from renowned academics, scientists and researchers including Charles Grob, Michael Mithoefer, Jenny Wade, William Keepin, Thomas Purton, Thomas Riedlinger, Fritjof Capra and more.
