Gandhola Monastery Gandolā, also called Gondla, Kundlah, or Guru Ghantal Gompa is about 18 km before Keylong in Lahaul, Himachel Pradesh, India on the road from Manali. It is located on a hill above the Tupchiling village at the sacred junction of the Chandra and Bhaga rivers, which together form the Chandrabhaga or Chenab Rive.
The monastery is said to have been founded by Guru Rinpoche or Padmasambhava in the 8th century CE. It is now connected with the Drukpa Kargyu sect of Tibetan Buddhism, but its history long precedes the formation of that sect. According to local tradition and also the Tibetan terma text, the Padma bKai Thang, discovered in 1326 CE, at Yarlung by Urgyan Lingpa, the site was associated with Padmasambhava. But the site was a Buddhist establishment even earlier than that:
A chased copper goblet dated to the 1st to 2nd century CE was found here in 1857 by a Major Hay and is considered to be evidence of Buddhist monks' cells being located in a cave monastery at that early time. A damaged marble head of Avalokitesvara also found here, is kept in the Guru Ghantal Monastery itself, and is claimed to date back to the time of Nagarjuna in the 2nd century CE. This seems to be the only monastery in the region other than Sani Monastery in Zanskar which has a history which is claimed to go back to Kushan times.
