Yeshe Ö (Lha bla ma ye shes ʼod) was born into one of the ruling families of western Tibet in the tenth century. He succeeded in uniting a large area before taking monastic vows in 989. A surviving ordinance forbids certain tantric practices, which is consistent with what is described in his biography as his attempts to suppress Bon and certain tantric practices.
The biography was written by Drakpa Gyaltsen, commonly known as Guge Panchen, the great pandita of Guge, in around 1480, probably using sources from Tholing, in western Tibet.
