This volume contains teachings from gurus of Tibet and India that were unkown to the Western world until its first publication in 1954. The book interprets the quintessence of the Supreme Path, the Mahayana, and reveals the yogic method of attaining Enlightenment. The original text of this yoga belongs to the Bardo Thodol series of treatises concerning various methods of attaining transcendence. The whole series is part of the Tantric school of Mahayana, and this particular work is attributed to the legendary Padmasambhava. An account of the great guru's life and doctrines precedes the text itself. Carl Jung's psychological commentary discusses the differences in Eastern and Western modes of thought. For the new reissue, Donald S. Lopez Jr writes a critical foreword to update and contextualize Evans-Wentz's work as an historical artefact contributing to the introduction of Tibetan Buddhism in the West.
