Tibetan: སློབ་དཔོན་པདྨ་འབྱུང་གནས
Wylie: slob dpon padma ‘byung gnas
Name variants: Guru Rinpoche (lit. “Precious Guru”).
Stories about Padmasambhava's life and accomplishments are full of legends, and he is widely venerated as a 'second Buddha' across Tibet, Nepal, Bhutan and the Himalayan states of India. However most scholars agree that he was a real historical figure and did visit Tibet in 8th century at the behest of Trisong Detsen [1]. Padmasambhava established Vajrayana Buddhism and the highest forms of Dzogchen in Tibet.
The trail left by Padmasambhava in Tibetan Medicine Sowa Rigpa is less known.
Among many spiritual treasures or terma left by him for people of future times, there were also some medical termas. Most of them are related to diagnostics, treatment and protection against serious infectious Nyen diseases (gnyan). The most famous treatise is “Vase With Healing Nectar” (Wyl. gso ba bdud rtsi bum pa; name variant: «Vase With Nectar Of Immortality» Wyl. ‘chi med bdud rtsi bum pa).
Moreover, it was Padmasambhava’s advice to hide Gyu Shi, the main treatise on Tibetan Medicine, in a pillar of Samye monastery for 150 years.
