The Ruby Rosary is Thinley Norbu's commentary on a short prayer written by his father, His Holiness Dudjom Rinpoche, who was a revered leader of the Nyingma lineage of Tibetan Buddhism as well as a revealer of treasures in the Tibetan tradition. The root text, entitled The Pearl Necklace, is a prayer of devotion to the eighteen primary masters of the Dudjom incarnation lineage, strung together into a necklace of liberated lifetimes. With lively storytelling, Thinley Norbu illuminates the life of each of these great yogis, scholars, and masters of the Buddha's teachings, from N den Dorje Chang, Shariputra, and Saraha to Dudjom Lingpa. It concludes with an account of the enlightened activities of Dudjom Rinpoche himself, a towering figure, thus completing this awe-inspiring portrait of a modern master.
