Anu Yoga (rjes su rnal 'byor).
As the second of the Three Inner Tantras, Anu Yoga emphasizes knowledge (prajna) rather than means (upaya) and the completion stage rather than the development stage. The view of Anu Yoga is that liberation is attained through growing accustomed to the insight into the nondual nature of space and wisdom. According to The Pool of White Lotus Flowers by Shechen Gyaltsab, the teachings of Anu Yoga appeared in this world when King Jah, a Dharma king also known as Lungten Dorje, Vajra Prophesy, received empowerment and instruction from the Lord of Secrets through which he gained full comprehension of the meaning. The scriptural lineage he received from the human vidyadhara Vimalakirti. The major texts of Anu Yoga are the Four Scriptures and the Summation. King Jah transmitted the Anu Yoga teachings to the master Uparaja, his own sons Shakputri, Nagaputri and Guhyaputri. Later lineage masters include Singhaputra, Kukuraja the Second, and Rolang Dewa (Garab Dorje).
All the masters up to this point attained enlightenment together with their retinue and departed from this world without leaving a body behind. The dissolution of the physical body can also be attained through accomplishment in the mundane practices of essence-extract, manipulation of and control over the vital essences (bindu) or through prana mastery, but the accomplishment attained through the practice of Anu Yoga is superior because of transmuting the physical body of karmic ripening into luminosity by means of the practice connected to the nonconceptual wakefulness of the path of seeing. Subsequent masters in the transmission of Anu Yoga include Vajrahasya, Prabhahasti, Shakya Little Light, Shakyamitra and Shakya Senge (Padmasambhava).
In India, Padmasambhava transmitted the teachings to Master Hungkara. From him the lineage continued to Dewa Seldzey, Dharmabodhi, Dharma Rajapala, Vasudhara of Nepal, Tsuklag Palgey, and finally Chetsen Kye from the country of Drusha who translated the Anu Yoga teachings into the Drusha language. This is the lineage that the translator Sangye Yeshe of Nub brought to Tibet. [RY]
