This section is devoted to the third (and second-highest) of the four classes of tantra – Yoga Tantra (རྣལ་འབྱོར་རྒྱུད་, rnal ’byor rgyud, yogatantra) – and begins with the root tantra of this class, the Compendium of Reality of all Thus-Gone Ones (དེ་བཞིན་གཤེགས་པ་ཐམས་ཅད་ཀྱི་དེ་ཁོ་ན་ཉིད་བསྡུས་པ་, de bzhin gshegs pa thams cad kyi de kho na nyid bsdus pa, Sarva-tathāgata-tattva-saṃgraha) (D.481). Much like the preceding Highest Yoga Tantra section, Situ’s catalog divides the texts here between works that focus primarily on “methods” (ཐབས་, thabs, upāya) and those that focus primarily on “wisdom” or “insight” (ཤེས་རབ་, shes rab, prajñā).
In terms of the historical development of Buddhist tantra in India, Yoga Tantra represents the first true cycle of tantras, with texts related in varying degrees, often through the central deity of Vairocana (རྣམ་པར་སྣང་མཛད་, rnam par snang mdzad). Butön Rinchendrup (བུ་སྟོན་རིན་ཆེན་གྲུབ་, bu ston rin chen grub, 1290-1364), arguably the foremost Tibetan scholar of Yoga Tantra, describes the structure of this cycle of texts as consisting of the following three types:
Situ’s catalog uses these categories in the “methods” section.
