Vimalamitra
Vimalamitra [Skt.] (Tib. drimé shenyen; Wyl. dri med bshes gnyen), one of the most learned Indian Buddhist masters. He went to Tibet in the ninth century, where he taught extensively, and composed and translated numerous Sanskrit texts. The quintessence of his teaching is known as the Vima Nyingtik, one of the Heart-essence teachings of the Great Perfection.
Vimalamitra spent thirteen years in Tibet, and then, promising to return to Tibet every hundred years as an emanation to further the Clear Light teaching of Dzogpachenpo, he left for the Wutaishan mountain in China. There he remains, in the rainbow body, the ‘Body of Great Transference’, and there he will remain until all of the 1002 buddhas of this Fortunate Kalpa have appeared. When they have all done so, he will once again go to Vajrasana in India, where he will manifest the state of complete and perfect enlightenment.
