The first human teacher of the tradition was said to be Garab Dorje (b. 55 c.e.), who had visions of Vajrasattva. Padmasambhava is the most famous and revered figure of the early human teachers and there are many legends about him, making it difficult to separate history from myth. Other early teachers include Vimalamitra, Jambel Shé Nyen, Sri Simha, and Jñanasutra. Most of these figures are associated with the Indian region of Oddiyana.
