Highest Yoga Tantra

Anuttarayoga Tantra (Sanskrit, Tibetan: bla na med pa'i rgyud), often translated as Unexcelled Yoga Tantra or Highest Yoga Tantra, is a term used in Tibetan Buddhism in the categorization of esoteric tantric Indian Buddhist texts that constitute part of the Kangyur, or the 'translated words of the Buddha' in the Tibetan Buddhist canon.

In the New Schools of Tibetan Buddhism, Anuttarayoga Tantra is the highest of four classes and is associated with the Mahamudra route to enlightenment. According to the Gelugpa tradition, in Highest Yoga Tantra, the Buddha taught the most profound instructions for transforming sensual pleasure into the quick path to enlightenment, which in turn depends upon the ability to gather and dissolve the inner winds (Sanskrit: prana) into the central channel through the power of meditation.

In the classification of the Dzogchen system, used by the Nyingma, it is considered equivalent to the Mahayoga tantras. The Dalai Lama XIV states: "old translation Dzogchen and new translation anuttarayoga tantra offer equivalent paths that can bring the practitioner to the same resultant state of Buddhahood".

The practice of Anuttarayoga Tantra in the Vajrayana tradition of Buddhism is characterized by the requirement of empowerment from a qualified guru, usually a lama, use of ritual techniques, and the practice of various meditative and subtle body yogas, to effect personal transformation and to attain enlightenment through the realization of the mindstream as a Meditational Deity, or a Yidam. According to Miranda Shaw, Anuttarayoga Tantra texts "have remained at the forefront of contemplation, ritual, and interpretation throughout the Himalayan Buddhist sphere".
