In this book, two great Tibetan Buddhist masters of the nineteenth and twentieth centuries challenge us to critically examine our materialistic preoccupations and think carefully about how we want to spend the rest of our lives. At the same time, they provide practical guidance in following the Buddhist path, starting from the most basic motivation and culminating in the direct experience of reality beyond the reach of conceptual mind. The root text is a teaching in verse written in the nineteenth century by Patrul Rinpoche, one of the outstanding teachers of his day. In the accompanying commentary, Dilgo Khyentse Rinpoche (1910-1991)--lineage holder of the Nyingma school and one of the great expounders of the Dharma in Europe and North America--expands upon the text with his characteristic compassion and uncompromising thoroughness. Patrul Rinpoche's fresh and piercing verses combined with Khyentse Rinpoche's down-to-earth comments offer a concise yet complete examination of the Buddhist path.
