Chakrasamvara

The Cakrasaṃvara Tantra (Sanskrit: चक्रसंवर तन्त्र) or Khorlo Déchok (Tibetan: འཁོར་ལོ་བདེ་མཆོག, Wylie: 'khor lo bde mchog) is considered to be of the mother class of the Anuttarayoga Tantra in Vajrayana Buddhism. It is also called the Discourse of Sri Heruka (sriherukabhidhana) and the Samvara Light (Laghusamvara). David B. Gray dates this tantra to the late eight or early ninth century.

The Cakrasamvara Tantra is mostly dedicated to describing rituals and meditations which produce either mundane siddhis (accomplishment) such as flight and the supramundane siddhi of awakening. These are achieved through deity yoga (visualizing oneself as the deity) and the use of mantras.

The central deity of the mandala, Saṃvara, is a form of Heruka, one of the principal yidam or meditational deities of the Sarma schools of Tibetan Buddhism.

Saṃvara is typically depicted with a blue-coloured body, four faces, and twelve arms, and embracing his consort, the wisdom dakini Vajravārāhī in Yab-Yum. Other forms of the deity are also known with varying numbers of limbs.

Saṃvara and Vajravārāhī are not to be thought of as two different entities, as an ordinary husband and wife are two different people; in reality, their divine embrace is a metaphor for the union of great bliss and emptiness, which are one and the same essence.
