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".
Anuttarayoga Tantra literally means 'Unexcelled Union Continuity'. While the term is frequently translated as 'Highest Yoga Tantra' in English writings, this is not quite accurate. The Tibetan term bla med (back translated to Sanskrit as anuttara) is a negation of a comparative—not or none (med/an-) higher (bla /uttara)—rather than a superlative. Had the authors of this term intended to indicate directly "highest," superlatives were readily available: e.g. mchog ("supreme" or Sanskrit uttama, "highest"). Rather, they chose consistently to use a comparative rather than a superlative. Similarly, the terms used in Sanskrit also uniformly utilize comparatives: yogottara ("higher than yoga") and niruttara (also a negation of the comparative). English usage, and European usage in general, has largely overlooked this nuance. The literal translation of the Sanskrit term "Anuttarayoga" would be "Unsurpassable Union" in English.
As scholar Isabelle Onians explains: "Yoginitantras are in the secondary literature often called Anuttarayoga. But this is based on a mistaken back translation of the Tibetan translation (rnal byor bla med kyi rgyud) of what appears in Sanskrit texts only as Yogānuttara or Yoganiruttara (cf. SANDERSON 1994: 97-98, fn.1)."
In the New Schools of Tibetan Buddhism, the four categories of tantras are Kriyā tantra, Caryā tantra, Yoga tantra and Anuttarayoga tantra. A further sub-classification is sometimes made among Anuttarayoga tantras into 'Father', 'Mother', and 'Non-dual' tantras, although this latter category is the subject of some controversy.
In the Nyingma school of Tibetan Buddhism, Anuttarayoga tantra is sometimes used as a synonym for the Mahāyoga tantra of their nine-yāna formulation, wherein six levels are articulated in two triads, the 'Outer' and 'Inner' tantras. The Outer Tantras are Kriyā, Caryā, and Yoga tantra. The Inner Tantras are Mahāyoga, Anuyoga, and Atiyoga.
Five collections of Anuttarayoga tantras became prominent in Tibet initially:
To date, the term 'Anuttarayoga Tantra' has not been discovered in Indian sources, wherein the categories used are Mahāyoga, and Yogottara, Yoganiruttara, or Yoginī-tantras for what the Tibetans consider "Father" (pha rgyud) and "Mother" Tantras (ma rgyud).
The mahāyoga-tantras of Pala Empire India became known in Tibet as 'Father Tantras' (pha rgyud). According to the Gelug view, following Tsongkhapa's reasoning, Father Tantras emphasize the creation of a Buddha form through the cultivation of an illusory body, on the basis of practices with the energy system of the subtle body. Earlier Sakya masters and Kagyu scholars had viewed Father Tantras as emphasising the practice of blissful awareness. Father Tantras have also been seen as emphasizing the use of anger (pratigha) as the path of practice, focusing on the emptiness aspect of Buddha nature. The post-Tsongkhapa Sakya scholar Tagtsang Lotsawa identified Father Tantras as those that emphasise the secret, or hidden, empowerment of the four empowerments of Anuttarayoga Tantra. The secret empowerment plants seeds for achieving an illusory body. Among the Father Tantras are Guhyasamāja and Yamāntaka.
The yoginī-tantras which became known in Tibet as 'Mother Tantras' (ma rgyud) emphasize the development of enlightened awareness (the "mind" of the illusory body) through the cultivation of the fundamental pure mind of all beings, known as 'brilliance' (prabhāsvara) (frequently translated, following the Tibetan, as 'clear light'). They focus on devotion as the foundation of tantric practice.[failed verification] They are also considered to emphasize the utilization of desire (tṛṣṇā) as the path of practice, focusing on the brilliant (prabhāsvara) aspect of Buddha nature. Among the Mother Tantras, the most prominent is the Cakrasaṃvara. The practice of Vajrayogini evolved out of the Cakrasaṃvara and is now a de facto practice in its own right. Other Mother Tantras are Hevajra Tantra and Caṇḍamahāroṣaṇa.
Non-dual tantras utilize both anger and desire as an antidote to delusion (avidyā), focusing on both the physical and mental, void and brilliant, aspects of enlightened mind. The example typically advanced for this category is the Kālacakra Tantra. The Sakya tradition also considers Hevajra to be a non-dual tantra but other traditions classify it as a yoginī-tantra.
In the Deity Yoga practices of Anuttarayoga Tantra, two stages are practiced: the Generation Stage and the Completion Stage. In some tantras both stages can be practiced concurrently, in others 'Generation Stage' must be perfected before starting to practice 'Completion Stage'.
Schaeffer holds that the Profound Inner Meaning (Tibetan: ཟབ་མོ་ནང་དོན, Wylie: zab mo nang don) Zabmo Nangdon is a major work of 'Rangjung Dorje' (Tibetan: རང་འབྱུང་རྡོ་རྗེ, Wylie: rang 'byung rdo rje) (1284–1339), the third Karmapa, born to a Nyingma family he received the full transmission of the Nyingma tradition, in addition to the Karma Kagyu. This text forms a textbook and ready reference to accompany the sadhana of those initiated into the Anuttarayogatantras.
