Providing a rare glimpse of feminine Buddhist history, Niguma, Lady of Illusion brings to the forefront the life and teachings of a mysterious eleventh-century Kashmiri woman who became the source of a major Tibetan Buddhist practice lineage. The circumstances of her life and the extraordinary qualities ascribed to her are analyzed in the greater context of spiritual biography and Buddhist doctrine. More than a historical presentation, Niguma's story raises the question of women as real spiritual leaders versus male images of "feminine principle" and other related contemporary issues.<BR><BR>This volume includes the thirteen works that have been attributed to Niguma in the Tibetan Buddhist canon. These collected works form the basis of an ancient lineage, Shangpa, which continues to be actively studied and practiced today. These works include the source verses for such esoteric practices as the Six Yogas, the Great Seal, and the Chakrasamvara and Hevajra tantric practices that are widespread in Tibetan traditions. Also included is the only extant biography, which is enhanced by the few other sources of information on her life and work.
