In this twelfth volume of The Treasury of Precious Instructions, Jamg n Kongtrul Lodr Taye presents a second collection of compiled teachings and practices of the Shangpa Kagyu tradition of Tibetan Buddhism, focusing on the teachings of the lineages of two Indian female celestial beings, Niguma and Sukkhasiddhi. The Treasury of Precious Instructions by Jamg n Kongtrul Lodr Taye, one of Tibet's greatest Buddhist masters, presents essential teachings from a broad spectrum of practice lineages that existed in Tibet. Volumes in this series may be engaged as practice manuals while also preserving ancient teachings significant to the literature and history of world religions. Volume 12 of the series is the second of two volumes that present teachings and practices from the Shangpa Kagyu practice lineage of Tibetan Buddhism. This tradition derives from the female celestial beings, or ḍakinīs, Niguma and Sukhasiddhi and their disciple, the eleventh-century Tibetan yogi Khyungpo Naljor Tsultrim G npo of the Shang region of Tibet. There are forty texts in this volume, beginning with Jonang Taranatha's classic commentary and its supplement expounding the Six Dharmas of Niguma. It includes the definitive collection of the tantric basis of the Shangpa Kagyu-the five principal deities of the new translation (sarma) traditions and the Five-Deity Cakrasamvara practice. The source scriptures, liturgies, supplications, empowerment texts, instructions, and practice manuals were composed by Tangtong Gyalpo, Taranatha, Jamg n Kongtrul, and others.
