A very important Geluk incarnation line with its primary seat at Labrang monastery in Amdo, one of the six great monasteries of Tibet, founded by the First Jamyang Zhepa, Jamyang Zhepai Dorje with the patronage of a Quoshot Mongolian ruler. Within the Geluk hierarchy, the incarnations of Jamyang Zhepa are superseded only by the Dalai Lama and the Panchen Lamas. The Jamyang Zepas maintained religious and secular authority over Labrang and all of its territories. The line dates from the mid-17th century.
