The Drub-dra schools he has established in the West are a continuation of the model of the Drub-dra school founded by Zhu Nam-gyal Drak-pa in the early 20th Century at the waist of Mount Mo-meinin Dromo (upper Chumbi Valley), southern part of Tibet. This first Drub-dra was located at Dho-kyim (a rustic type of retreat house) which takes 3 hours on foot from His monastery Pungmo Gon. The present Drub-dra of the Zhu lineage is called Khyimsar Drub-dra.

Khemar Rinpoche and his elder brother Lama Sonam G. Khemsar are both regarded by their predecessors and their parents as Yang-sid-Trul-kus of Tshampa Yungdrung Wangyal the then 14th seat holder of Pungmo Gon. There is the notion in Yungdrung Bön and Buddhism that a Lama could reincarnate in to three trul-kus, each of them representing a different aspects (body, speech and mind).
