The full name of this foundational text of Tibetan medicine is ''Amṛita's Heart: The Tantras of the Secret Esoteric Instructions on the Eight Branches'' (''bDud rtsi snying po yan lag brgyad pa gsang ba man ngag gi rgyud''). The four tantras, or sections, are the Root Tantra, Explanatory Tantra, Instructional Tantra, and Final Tantra. There is debate about the origins and authorship of this text. Some regard it to be of Indian origin, translated into Tibetan by Vairochana; others say that it is an indigenous Tibetan work. For more on the history of this text, see Garrett 2008, 46–47; and Kilty 2010, 5–9. For a translation of the Root Tantra and Explanatory Tantra sections, see Clark 1995. +
