A translation from a Tibetan manuscript first translated into Tibetan in the 8th Century by Vairochana Rakshita, a famous translator during the early period of Buddhism in Tibet. The text presents itself as an esoteric work of Buddhism, but contains ideas that are considered unorthodox by most Buddhist traditions. It is possible that Gnostic or Upanishadic thinking are elements. Scholars interested in the early period of Buddhism in Tibet and the history of Indian philosophy, those interested in possible connections between Buddhist and non-Buddhist tradition, and those who wish to read authentic source material on the Great Perfection will be most interested.
