Zangchen
Zangchen, also known as Nyel Zangpoche, is a monastery in the mountain country of southern Tibet. Sonam Jungne founded it as a Nyingma house around the twelfth century, and it later became a Kadam institution. The monastery was an active centre for the study of monastic discipline. Among those who began their education there was Tsonawa Sherab Zangpo, a thirteenth-century master of the Vinaya and a holder of the Lamrim teaching lineage.
