Tenzin Norbu who was the 4th descendant of Drubthog Chekarwa bore two children, son Pow Dorji and daughter Dechhogma in Tibet. Pow Dorji became a learned saint, who was educated by Lhatshun Chhoki Jamtsho. On the other hand, the daughter Dechhogma gave birth to two sons, namely Chhogyel Norbu and Tenpa who grew up to be popular saints, under Lam Ngawang Chhogyel. The two sons were destined to be in the Lho (southern) part of Tibet or the Moen Yuel. Therefore, in the 16th century Chhogyel Norbu and Tenpa built Zarchen Samten Chholling and Kila Dechen Yangtse in Moen Yuel. On completion of these constructions they invited their uncle Pow Dorji from Tibet who resided in Kila Goenpa, initially known as Kila Dechen Yangtse. The cave in which he meditated is seen even today.
