Guru Rinpoche day:

Guru Rinpoche or Padmasambhava is the Buddha who established Tantric Buddhism in Tibet. At the esoteric level, he is the essence of all buddhas and masters. He is the Buddha of our troubled age, dispelling all negativities, and as such he occupies an important place in the hearts and in the practice of the Tibetans,

Padmasambhava ("Born from a Lotus"),also known as Guru Rinpoche (Precious Guru) and the Lotus from Oḍḍiyāna, was an tantric Buddhist Vajra master from India who may have taught Vajrayana in Tibet (circa 8th - 9th centuries).According to some early Tibetan sources like the Testament of Ba, he came to Tibet in the 8th century and helped construct Samye Monastery, the first Buddhist monastery in Tibet. However, little is known about the actual historical figure other than his ties to Vajrayana.
