Samding Dorje Phagmo Anuyoga (Devanagari: अनुयोग 'further yoga') is the designation of the second of the three Inner Tantras according to the ninefold division of practice used by the Nyingma school of Tibetan Buddhism.
[1] Ray (2002: p. 124-125) mentions visualization, subtle body, chakra, prana, nadis, bindu and pure land: Anuyoga-yana is associated with the feminine principle and is for those whose principal obstacle is passion.
[3] Dudjom (1904–1987), et al. (1991: p. 460 History) relate an important source that impacts on the story of King Ja (particularly the narrative of the Buddhadharma relics falling from the sky upon the royal palace) a happenstance which is implied to be concurrent with the emergence of the texts of Anuyoga in Sri Lanka with the provision of a quote of what Dudjom et al. identify as a "prediction" found in the fifth chapter of the 'Tantra which Comprises the Supreme Path of the Means which Clearly Reveal All-Positive Pristine Cognition' (Wylie: kun bzang ye shes gsal bar ston pa'i thabs kyi lam mchog 'dus pa'i rgyud, Nyingma Gyubum Vol.3) which Dudjom, et al., render in English thus: The Mahayoga tantras will fall onto the palace of King Ja.
In doing so, they made the Compendium Sūtra a major part of their system, placing it alongside the Guhyagarbha Tantra and the kun byed rgyal po to make their famous “sūtra-tantra-mind triad” (mdo rgyud sems gsum).
These three works became the chief canonical texts of the Zur’s transmitted precepts, corresponding to the respective doxographical classes of Anuyoga, Mahāyoga, and the mind series of Atiyoga (sems sde).
