The only book in English on a popular Tibetan Buddhist lineage prayer that explains how it can be used as a guide to practice. One of the most beloved and oft-recited prayers in the Kagyu tradition of Tibetan Buddhism, The Mahamudra Lineage Prayer combines a supplication to the Mahamudra lineage with a concise guide to Mahamudra practice and the stages of the path to enlightenment. In this commentary on the prayer, Thrangu Rinpoche teaches in his down-to earth yet direct manner the importance of the Mahamudra lineage, how to develop renunciation and devotion through the common and uncommon preliminary practices, and how to practice calm abiding (Shamatha) and insight (Vipashyana) meditation in the Mahamudra tradition. He explains that Mahamudra teachings are easy to practice yet are very powerful, and are especially appropriate for serious Western Dharma students.
