Zasep Tulku Rinpoche, in his first incarnation, was the renowned Kargyupa teacher Lama Chabdak, whose name means "The Precious Owner of the Cosmos."
Lama Chabdak was born in the 14th century in the beautiful Kham province of east Tibet, during the great flourishing of Lord Buddha's teachings in the Land of Snows. He was a contemporary of the teacher of Tzong Khapa, His Holiness Rolpai Dorje, the famous fourth Karmapa who gave the eight Upasaka Precepts to Je Rinpoche.
Having studied Sutra and Tantra under many great meditators, Lama Chabduk
founded Zuru Gompa, a monastery at Lharog Gedun Dorje Jungpug in Kham province,
and gave many teachings there. His reincarnations had a strong connection
with the incarnations of Gyalwa Karmapa.
