Padmasambhava is the Lotus Born Tantric Buddha who established Vajrayana Buddhism in Tibet in the 9th century upon the invitation of Chögyal Trisong Détsen.
Ngak’chang Rinpoche comments:
stands out in the history of the world’s traditions of Buddhism as being a major
figure for the dissemination of the widest and most thoroughly encompassing
vision of Dharma. He is utterly unprecedented in every sense in terms of
compassion, wisdom, and power.
