Hevajra Tantra

Hevajra (Tibetan: ཀྱེའི་རྡོ་རྗེ་ kye'i rdo rje / kye rdo rje; Chinese: 喜金刚 Xǐ jīngāng;) is one of the main yidams (enlightened beings) in Tantric, or Vajrayana Buddhism. Hevajra's consort is Nairātmyā (Tibetan: bdag med ma).

The Hevajra Tantra, a yoginītantra of the anuttarayogatantra class, is believed to have originated between the late 8th (Snellgrove), and the late 9th or early 10th centuries (Davidson), in Eastern India, possibly Kamarupa. Tāranātha lists Saroruha and Kampala (also known as "Lva-va-pā, "Kambhalī", and "Śrī-prabhada") as its "bringers":

.. the foremost yogi Virūpā meditated on the path of Yamāri and attained siddhi under the blessings of Vajravārāhi,...His disciple Dombi Heruka..understood the essence of the Hevajra Tantra, and composed many śāstras like the Nairātmā-devi-sādhana and the Sahaja-siddhi. He also conferred abhiṣeka on his own disciples. After this, two ācāryas Lva-va-pā and Saroruha brought the Hevajra Tantra. ... Siddha Sarouha was the first to bring the Hevajra-pitṛ-sādhana

Another lineage, mentioned by Kongtrul, goes from Vilāśyavajra to Anangavajra to Saroruha and thence to Indrabhuti.

Jamgon Amyeshab, the 28th throne holder of Sakya, considers the Hevajra Tantra to have been revealed to Virupa by the Nirmanakaya Vajranairatma. This tantra is also considered by him to have been revealed to Dombhi Heruka, Virupa's senior disciple, by Nirmanakaya Vajranairatma, from whom the main Sakya exegetical lineage of the Hevajra tantra descends.

The Yogaratnamālā, arguably the most important of the commentaries on the Hevajratantra, was written by one Kṛṣṇa or Kāṇha, who taught Bhadrapada, another commentator, who in turn taught Tilopa, the teacher of Nāropa, who himself wrote a commentary. He, in turn, passed on his knowledge of this tantra to Marpa (1012-1097 AD), who also taught in Tibet. Marpa also received instruction in the Hevajratantra from Maitrīpa, alias Advayavajra, who was banished from Vikramashila for practicing with a yoginī during the time of Atīśa's abbothood.
