Around 1951 Tsondu reached the Garuda Valley near the western part of Mt. Kailash. At the Gurgyam Dongak Dak Gyay Ling monastery, he met Chungtul Jigme Namkhai Dorje Rinpoche. Chungtul Rinpoche had come from eastern Tibet and had settled in what had once been a strong Bon environment. The Garuda Valley by this time, however, had become a strong Nyingma establishment. Chungtul Rinpoche skillfully combined elements of both Bon and Nyingma teachings in order to attend to the needs of the local population; and, in this way, was able to propagate the Bon doctrine in the Garuda Valley again.
When Tsondu arrived at the Gurgyam monastery, it was not his intention to remain long. He explained to Chungtul Rinpoche that he wanted to continue his pilgrimage and return to Tangra. Chungtul Rinpoche, with another idea in mind, told Tsondu that he had reestablished Bon in the Garuda Valley; and that as he was getting older, he needed someone to remain and train his yogis and monks. He requested Tsondu to renounce his return to Tangra as the Bon religion was well established there; and instead, create a three-year retreat center at Gurgyam monastery. Tsondu, recognizing that this would be more useful than continuing his pilgrimage, acceded to Chungtul Rinpoche=s request and became the teacher of the retreat center.
