“[A] brilliant disquisition on . . . mostly unpublished texts for three allied systems of tantric thought and praxis (sexual, alchemical, and hatha yogic).” —The Journal of Asian Studies The Alchemical Body excavates and centers within its Indian context the lost tradition of the medieval Siddhas. Working from previously unexplored alchemical sources, David Gordon White demonstrates for the first time that the medieval disciplines of Hindu alchemy and hatha yoga were practiced by one and the same people, and that they can be understood only when viewed together. White opens the way to a new and more comprehensive understanding of medieval Indian mysticism, within the broader context of south Asian Hinduism, Buddhism, Jainism, and Islam. “White proves a skillful guide in disentangling historical and theoretical complexities that have thus far bedeviled the study of these influential aspects of medieval Indian culture.” —Yoga World “Anyone seriously interested in finding out more about authentic tantra, original hatha yoga, embodied liberation . . . sacred sexuality, paranormal abilities, healing, and of course alchemy will find White’s extraordinary book as fascinating as any Tom Clancy thriller.” —Georg Feuerstein, Yoga Journal “Remarkable . . . a study of the language of mystic experience and expression—the multitudinous symbols, rituals, and doctrines of the medieval siddhis, yogis, and alchemists.” —Skeptic Meditations
