This book uniquely provides first-hand insights into the spirit-mediums of Upper Tibet, the men and women who channel the gods. John Victor Bellezza here for the first time presents the conclusions of his extensive research in the region itself, shedding light on the historical context, the tradition, characteristics, ceremonies, and paraphernalia of the phenomenon. With extensive interviews with spirit-mediums, including interpretive material drawn from Tibetan texts; annotated translations of rituals devoted to the major deities of the spirit-mediums; and annotated translation of Bon literature relevant to the origins of spirit-mediums, and concluding with a chapter on Bon literary references to the ritual implements and practices. A major source-book.
