"Dzogchen or the Great Perfection is the apex of Tibetan Buddhism, and Longchen Rabjam is recognized as the pre-eminent master of Dzogchen and one of Tibet's greatest writers and sages. His Treasury of Reality encompasses and optimizes the radical precepts of Dzogchen and is a shining example of why people continue to turn to the traditions of Tibet for spiritual and personal transformation. Transcending the Tibetan context, Longchen Rabjam's book is a manual of practical wisdom for all people of all times, cultures, and traditions. Dzogchen teaches the natural perfection of all experience, phenomena, and life, just as it is, with no need to alter or fabricate complex ideas or philosophical views. This discipline of spiritual transcendence provides the key not only to our inner enlightenment but to the health and survival of our planet"--Publisher's description.
