This book is a commentary on an ancient, well-known Tibetan Buddhist prayer of aspiration that expounds on the Dzogchen path to enlightenment. Addressing such fundamentals as the guru-student relationship, the role of faith in Vajrayana Buddhism, recognizing basic awareness, and the notion of reality that is beyond mental concepts, it is a clear and accessible explication of a complex system of philosophy and meditation techniques that are central to Tibetan Buddhism.
