Query: Ruthless Compassion

Linrothe isolates the wrathful deities as an especially revealing ideological marker in the development of esoteric Buddhism. He identifies three distinct phases according to subsidiary, complementary, and central importance of wrathful deities in images made for and by practitioners. In a few cases South Asian images are cross-referenced with comparable examples from the western Himalaya, Tibet, and China, and Sanskrit and Tibetan texts are joined by select Chinese translations to stage a mutually informative dialogue between text and image.Ruthless Compassion offers a visual history of esoteric Buddhism centered on the changing representations of the wrathful deity. Its examination of a resource too long neglected by historians of religion and art alike makes Ruthless Compassion a uniquely valuable contribution to the field of Buddhist studies.
