Guru Pema Evam Chokgar was a tantric community north of the Brahmaputra river established by Tashi Tobgyel in the late 16th century. The community maintained the Jangter (Northern Treasures) tradition. Later the location was developed and expanded by his Tashi Tobgyel's son the Third Dorje Drak Rigdzin, Ngakgi Wangpo into Dorje Drak monastery, which became the main center for the Jangter tradition and at one point had over fifty branch monasteries.
