Newar Buddhism is the form of Vajrayana Buddhism practiced by the Newar people of the Kathmandu Valley, Nepal. It has developed unique socio-religious elements, which include a non-monastic Buddhist society based on the Newar caste system and patrilineality. The ritual priests (guruju), vajracharya (who perform rituals for others) and shakya (who perform rituals mostly for their own families) form the non-celibate religious sangha while other Buddhist Newar castes like the Urāy act as patrons. Uray also patronise Tibetan Vajrayanin, Theravadin, and even Japanese clerics.
