Inner Tantras

The Inner Tantras are the final three divisions in the ninefold division of practice according to the Nyingma school of Tibetan Buddhism. They comprise the Mahayoga, Anuyoga and Atiyoga. This system divides the whole of the Buddhist path into three divisions of three and is in contrast to the division of the Sarma, or New Translation schools which use a fourfold division. The three divisions of the Inner Tantra correspond roughly to the highest category of tantras of the New Translation schools, there known as Anuttarayoga Tantra.
