Padmasambhava
Padmasambhava ('Born from a Lotus'), also known as Guru Rinpoche ('Precious Guru'), was a semi-legendary tantric Buddhist Vajra master from medieval India, who according to hagiographical sources fully revealed the Vajrayana in Tibet, circa 8th – 9th centuries. He is considered an emanation or Nirmāṇakāya of Shakyamuni Buddha as foretold by the Buddha himself.
