This translation of a fundamental Tantric text reveals the richness and profundity of the intellectual and contemplative traditions of Tibetan Buddhism. The text describes the Four Foundation Practices that all practitioners of Vajrayana Buddhism must complete. The nature of impermanence, the effects of karma, the development of an enlightened attitude, and devotion to the guru are among the subjects treated in this book. Three eminent contemporary Tibetan Buddhist masters-Kalu Rinpoche, Deshung Rinpoche, and Chogyam Trungpa Rinpoche-explain the significance of The Torch of Certainty for modern-day students and practitioners of Tibetan Buddhism.
