The ''Compendium of Principles'' marks the emergence of mature Indian Buddhist tantra at the end of the seventh century, and it immediately spawned a body of literary progeny that has played a central and enduring role in the development of tantric Buddhism in India, Tibet, China, and Japan. Consolidated over time into traditions known in some Indian circles as Yoga Tantra, they spread as widely as Śrı Lanka, Southeast Asia, Khotan, Mongolia, and Sumatra.〔Weinberger, Steven Neal (2003).
