Paldmashambhava so known as Guru Rinpoche was an 8th-century Buddhist master from the Indian subcontinent. Although there was a historical Padmasambhava, little is known of him apart from helping the construction of the first Buddhist monastery in Tibet at Samye, at the behest of Trisong Detsen,and shortly thereafter leaving Tibet due to court intrigues. A number of legends have grown around Padmasambhava's life and deeds, and he is widely venerated as a second Buddha by adherents of Tibetan Buddhism in Tibet, Nepal, Bhutan, the Himalayan states of India, and elsewhere.In Tibetan Buddhism, he is a character of a genre of literature called terma, an emanation of Amitabha that is said to appear to tertatilde in visionary encounters and a focus of guru yoga practice, particularly in the Rim&Atilde schools. The Nyingma school considers Padmasambhava to be a founder of their tradition.
