This image of Padme Sambhava, a.k.a. Guru Rinpoche and Urgen Guru, is in Tupu, the cave at the forest edge above Melemchi where he lived in the 8th century. The cave is opened once a year for the festival Tupu Sechu which marks the end of his meditation there. It has been a place for medititative retreat and is usually not possible to enter.
