Gampopa was the main disciple of Milarepa and one of the founders of the Kagyu lineage of Tibetan Buddhism. Besides writing the Jewel Ornament of Liberation, Gampopa distilled the Buddhist path into four short lines or truths, called dharmas. These lines became known as the Four Dharmas of Gampopa. This book gives these four lines along with a detailed commentary on each by Thrangu Rinpoche.
