His rare combination of qualities gives multiple dimensions to the story he tells--spiritual, anthropological, and political. Impossible to put down once you pick it up." --Wendy Doniger, DPhil, PhD, University of Chicago Divinity School, author of Dreams, Illusion, and Other Realities
"A rare mixture of exhaustive scholarship and gripping first person account... Find room in your backpack. You'll want to return to this one again and again as your journey unfolds." --Richard Doyle, PhD, Penn State University, author of The Ecodelic Hypothesis: Plants, Rhetoric and the Evolution of the Noösphere
"Encyclopedic in scope, theoretically nuanced, eminently readable, and thoroughly spellbinding. A tour de force... the definitive work on this topic." --Bonnie Glass-Coffin, PhD, Utah State University, author of The Gift of Life: Female Spirituality and Healing in Northern Peru
"This is a classic volume that provides an unsurpassed understanding of the healing power of shamanism, its use of spiritual rituals and visionary plants, its light and dark sides, its sophistication and humor." --Stanley Krippner, PhD, Saybrook Graduate School and Research Center, co-author of Spiritual Dimensions of Healing
"The real deal--scholarly and quite compellingly written... Treated as an apprentice, the author was able to gain insights into the rituals, beliefs, and practices that form the social context and the inner world of shamanism." --David Lukoff, PhD, Institute of Transpersonal Psychology, author of "Visionary Spiritual Experiences and Mental Disorders"
"Elegantly written... incorporating thoughtful analyses of psychological, cultural, and spiritual perspectives. A very valuable contribution to the literature." --Ralph Metzner, PhD, Green Earth Foundation, author/editor of Sacred Vine of Spirits and Sacred Mushroom of Visions
