Tibetan yoga is the hidden treasure at the heart of the Tibetan Tantric Buddhist tradition: a spiritual and physical practice in pursuit of an expanded experience of the human body and its energetic and cognitive potential. Ian A. Baker progressively introduces the core principles and practices of Tibetan yoga in this pioneering overview. In addition to meditations, visualizations and practices for the breath and body, these include elements rather less familiar to yoga initiates in the West, including sexual yoga; dream yoga or lucid dreaming; and yoga practices enhanced by psychoactive plant or mineral substances. Baker draws on contemporary scientific research and contemplative and humanitarian traditions to enable the reader to understand these practices. The book includes ethnographic photography and works of Himalayan art that have never been published before, as well as illustrations of yogic practice and theory from historical books of instruction.
