In 1980, Michael Harner blazed the trail for the worldwide revival of shamanism with his seminal classic The Way of the Shaman. In this long-awaited sequel, he provides new evidence of the reality of heavens. Drawing from a lifetime of personal shamanic experiences and more than 2,500 reports of Westerners’ experiences during shamanic ascension, Harner highlights the striking similarities between their discoveries, indicating that the heavens and spirits they’ve encountered do indeed exist. He also provides instructions on his innovative core-shamanism techniques, so that readers too can ascend to heavenly realms, seek spirit teachers, and return later at will for additional healing and advice. Written by the leading authority on shamanism, Cave and Cosmos is a must-read not only for those interested in shamanism, but also for those interested in spirituality, comparative religion, near-death experiences, healing, consciousness, anthropology, and the nature of reality.Praise for Michael Harner and The Way of the Shaman   “What Yogananda did for Hinduism and D.

Grob   “Wonderful, fascinating.… Harner really knows what he’s talking about.” —Carlos Castaneda, best-selling author of The Teachings of Don Juan and The Active Side of Infinity   “An intimate and practical guide to the art of shamanic healing and the technology of the sacred. Michael Harner is not just an anthropologist who has studied shamanism; he is an authentic white shaman.” —Stanislav Grof, author of The Adventure of Self-Discovery   “Harner has impeccable credentials, both as an academic and as a practicing shaman.

He also proves that a person can be both a scientist and a shaman.” —Bo Bair Rinchinov, Siberian Buryat shaman
