Treasury of Tibetan Medical History is a facsimile of Dr. Pasang Yonten Arya’s award-winning chronological account of the ancient origins, early development, flourishing, and spread of Sowa Rigpa from prehistoric times up until the twentieth century. Calligraphed in block-style script and first printed in 1989, this unprecedented textual research provides a comprehensive overview of the major time periods, events, and characters that have shaped the dynamic history of Tibetan medicine. Besides highlighting the underestimated contributions of the Bön and revealed treasure traditions and tracing the lineages of all influential medical schools, this monograph is also enriched with numerous biographical sketches of renowned scholars and physicians. Containing a unique chronicle of Sowa Rigpa’s survival in Indian exile, as well as the transition to modern Tibetan medical education, it is both a landmark reference and a primary historical source.
