This work offers a new translation of the ancient Buddhist text originally composed by Padmasambhava, an Indian spiritual master of the eighth century. Hidden in the mountains of Tibet, the text remained concealed until the 14th century when it was discovered and revealed by Karma Lingpa. A manual of instructions designed to facilitate the inner liberation of the dead or dying person at the moment of death, this new translation of one of the world's greatest spiritual classics includes a detailed introduction by Dzogchen Buddhist master Chogyal Namkhai Norbu.
