“This is a powerful comparative project that brings together the phenomenology of Hebrew prophetic literature and modern psychedelic experiences in order to develop a new theoneurology, that is, a new model of how the brain and the microchemistry of DMT may well mediate, shape, and filter both consciousness itself and humanity’s millennia-old encounter with “God.”

Jeffrey J. Kripal, Ph.D., Chairman of Department of Religious
Studies, Rice University, author of Authors of the Impossible


“Not since Huxley’s landmark The Doors of Perception has such a profound treatise emerged exploring the nexus of consciousness, the brain, and mind-altering substances.  Strassman, accomplishes this tour de force by wisely inverting the vector of the field of neurotheology to that of theoneurology. This book exemplifies rigorous science and keen historical analysis, and is a significant contribution to human welfare. A delight to read, a sparkling exercise in clarity.”

Larry Dossey, M.D., author of One Mind


“This book is a revelation. Strassman has written a daring and remarkable book that connects contemporary psychedelic explorers with the roots of the Jewish Prophetic Tradition. Here is a book that shows us how this ancient model of prophecy might provide an elegant and powerful language for the ennobling of our yearning for and journey towards expanded consciousness.”

Rabbi Shefa Gold, author of The Magic of Hebrew Chant


“A very surprising and refreshing book. Strassman is unique, and opens up completely new perspectives. I have learned a lot from this well-written book, and I am sure that others readers will do so too. Strassman took me far beyond familiar ways of thinking about brain, minds, and interactions with non-human intelligences.”

Rupert Sheldrake, Ph.D., author of Science Set Free


“As Rick Strassman’s extraordinary new book explains, the Hebrew prophetic tradition provides an unexpectedly powerful lens for wrestling with the meaning of our psychedelic experiences. Strassman’s model of theoneurology provides the proper context for viewing the religious importance of our mystic visions.”

Alex Grey, artist, author, co-founder of CoSM, Chapel of Sacred Mirrors


“The book will be of interest to those with primary interest in religious experience as well as those with primary interest in psychedelic experience and altered states of consciousness.”

Roland R. Griffiths, Ph.D., Departments of Psychiatry and Neuroscience, Johns Hopkins University School of Medicine


“People interested in DMT, hallucinogens, spirituality, monotheistic religion, Buddhism, consciousness studies and philosophy will find this book stimulating. I commend Strassman for his bold attempt to bridge science and religion, thereby risking attack from both sides. This is the kind of book that will advance knowledge… A deep and intense study outside the usual boundaries of education.”

Jeremy Narby, Ph.D., anthropologist and author of The Cosmic Serpent


“By utilizing the world view of the Medieval Jewish philosophers Strassman has presented this often emotionally laden and controversial subject in such a rational and scientific manner that even the skeptic and agnostic among us will be pleasantly surprised at how intriguing the confluence of God, the Hebrew Bible and psychedelic endogenous DMT can be.”

Rabbi Joel David Bakst, author of The Jerusalem Stone of Consciousness – DMT, Kabbalah   & the Pineal Gland


“This is a brilliant, perceptive and illuminating book. Strassman states that the best way to understand the DMT experience is to see how closely it follows the experience of Old Testament prophets and vice versa. I was surprised to find out he was right.”

James Fadiman, Ph.D., author of The Psychedelic Explorer’s Guide


“Dr. Strassman’s theoneurology theory is a coherent and successful undertaking, by a uniquely qualified and situated medical researcher of altered states of consciousness.”

Alex S. Kohav, Ph.D., author of The Sôd Hypothesis


“A stimulating work which while controversial will be of interest to students of the bible and human thought.”

Rabbi Norman (Chaim) Strickman, Ph.D., Department of Judaic Studies, Tuoro College, author of Without Red Strings or Holy Water: Maimonides’ Mishneh Torah.


“This book provides enough heresy to provide a stimulating read for both atheists and believers!”

Rabbi Michael Ziegler, cofounder of The Chaplaincy Institute, Berkeley, CA.


“A detailed and ground breaking study. The book is a tour de force and a strong counterpoint to prevailing bottom-up explanations involved in neurotheology, asserting the primacy of the spiritual rather than the material.”

David Lorimer, program director, The Scientific and Medical Network


“A fascinating and provocative examination of altered states of consciousness caused by psychedelics, and in particular the powerful, prototypic hallucinogen, DMT.”

Charles S. Grob, M.D., Departments of Psychiatry and Pediatrics, UCLA School of Medicine


“Rick Strassman, M.D., always provokes and delights.  His latest work explores the fractal edges of religion and mind, covering such seemingly far-flung topics as the Hebrew Bible, prophetic visions, DMT, the mysteries of consciousness, and more. Buy this book and feed your brain!”

Clifford A. Pickover, Ph.D., author of Sex, Drugs, Einstein, and Elves


“In science, religion, politics, – everywhere in the academic and public domain – the dominance of spoken and written language is overwhelming. Rick Strassman’s new book helps to tilt the balance to the right direction describing elaborately the fundamental role of visions in our Judeo-Christian tradition.”
