Synopsis Dzogchen is the apotheosis of Tibetan Buddhism and Longchenpa is the pre-eminent master of Dzogchen, and one of Tibets's greatest mystical poets. His treasury of natural perfection encompasses and epitomizes the radical precepts of Dzogchen. Transcending the Tibetan context, Longchenpa delivers a manual of mystical wisdom for all people at all times, and shows why the western world has turned to Tibet for its mystical inspiration during the last half century. This transmission of timeless wisdom of the ancients of Tibet should take its place amongst the world's religious classics. Through the precept 'nonaction' - which is savoured like 'an old man basking in the sun' - Dzogchen teaches the natural perfection of all our experience, and all our lives, just as it is, without need of any alteration. This discipline provides the key not only to our inner enlightenment but to the health and survival of our planet.
