Jangsem Dawa Gyeltsen was an important figure in the transmission lineages of the deities Hayagrīva and Avalokiteśvara, and in the dissemination of the Avalokiteśvara fasting ritual or nyung-ne. A great visionary who apparently became quite wealthy later in life, Dawa Gyeltsen is known principally as a meditator, healer, miracle worker, and teacher of bodhicitta.
