'The Tibetan Book of the Great Liberation,' which was unknown to the Western world until its first publication in 1954, speaks to the quintessence of the Supreme Path, or Mahayana, and fully reveals the yogic method of attaining Enlightenment. Such attainment can happen, as shown here, by means of knowing the One Mind, the cosmic All-Consciousness, without recourse to the postures, breathings, and other techniques associated with the lower yogas. The original text for this volume belongs to the Bardo Thodol series of treatises concerning various ways of achieving transcendence, a series that figures into the Tantric school of the Mahayana. Authorship of this particular volume is attributed to the legendary Padma-Sambhava, who journeyed from India to Tibet in the 8th century, as the story goes, at the invitation of a Tibetan king. Padma-Sambhava's text per se is preceded by an account of the great guru's own life and secret doctrines. It is followed by the testamentary teachings of the Guru Phadampa Sangay, which are meant to augment the thought of the other gurus discussed herein.
