About Cakrasaṃvara Tantra

The Cakrasaṃvara Tantra or Khorlo Déchok 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.
