The Lotus-Born Teacher from Uḍḍiyāna, often known as Guru Rinpoche. During the reign of King Trisong Detsen in the eighth century, this great master subjugated the evil forces hostile to the propagation of Buddhism in Tibet, spread the Buddhist teaching of the Diamond Vehicle in that country, and hid innumerable spiritual treasures for the benefit of future generations. He is venerated as the Second Buddha, whose coming was predicted by the first one, Buddha Shākyamuni, to give the special teachings of the Diamond Vehicle. [NS]
