The Way of the Shaman, by Michael Harner.
An intimate and practical guide to the art of shamanic healing and the technology of the sacred. Harner has impeccable credentials, both as an academic and as a practicing shaman. Without doubt (since the recent death of Mircea Eliade) the world’s leading authority on shamanism. Mr. Harner has taken a misunderstood and often misinterpreted subject and has written a very good book for those who have little to no experience with cultural shamanism. He has extensive experience with native shamen and tells of his adventures in a way that allows the reader to grasp the ecstatic methods of these priests.
