The pioneering author of The Way of the Shaman continues his exploration of universal shamanism in this “wonderful, fascinating” guide (Carlos Castaneda)   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.
