Focusing on the lives and works of three "holy madmen" from the fifteenth century - the Madman of Tsang (Tsangnyon Heruka, or Sangye Gyeltsen, 1452-1507, and author of The Life of Milarepa), the Madman of U (Unyon Kungpa Sangpo, 1458-1532), and the Madman of the Drukpa Kagyu (Drukpa Kunle, 1455-1529). DiValerio shows how literary representations of these madmen came to play a role in the formation of sectarian identities and the historical mythologies of various sects. DiValerio also conveys a well-rounded understanding of the human beings behind these colorful personas by looking at the trajectories of their lives, their religious practices and their literary works, all in their due historical context.
