Tashi Tobgyel (May. 15)
Jangdak Tashi Tobgyel was the founder of Sangngak Tekchok Choling Monastery. He was the reincarnation of Ngari Panchen Pema Wangyel and the father of Rigdzin Ngakgi Wangpo, the founder of Dorje Drak Monastery.
Ngakgi Wangpo was the main lineage holder of the Jangter, or Northern Treasures tradition. He was the founder of Dorje Drak Monastery and served as its first throne holder. For this he earned the title of Dorje Drak Rigdzin, which was posthumously assigned to his previous incarnations; at least in some sources; Ngakgi Wangpo is occasionally known as the First Dorje Drak Rigdzin.
Lekden Dorje was recognized as the rebirth of Rigdzin Godemchen and posthumously given the title of Second Dorje Drak Rigdzin. He was the younger brother of Ngari Panchen Pema Wanggyel, with whom he established the community that later grew into Dorje Drak Monastery, one of the main Nyingma monasteries in Tibet.
