Monks traditionally studied thirteen major sutra and tantra texts of the Nyingma, and learned the practices stemming from various terma, especially from the lineage of Terdak Lingpa.

In 1965, Khochhen Rinpoche and small group of monks began the process of re-establishing Mindrolling monastery located near Clement Town, in Dehradun, Uttarakhand state, India.

He was considered at an early age to be the reincarnation of Namdrol Sangpo Rinpoche of Khochhen Monastery by the 8th Mindrolling Khenchen.

Rinpoche established the Ngagyur Nyingma College or Institute of Advanced Buddhist Studies in 1991, which teaches a nine-year course including Sutra and Tantra to approximately one hundred monks.

Near Mindrolling Monastery, Rinpoche erected a 190 feet high Stupa of the Buddha’s Descent from the God Realms, inaugurated in 2002, and dedicated to world peace.

In East India in Kalimpong, Darjeeling, state of West Bengal Rinpoche constructed a new monastery in the Mindrolling lineage, inaugurated on 1 March 2007, as well as a school for the village children and a must needed clinic.

In Taiwan Rinpoche founded several Mindrolling Dharma centres in Taipei, Changhua, Taichung City and Kaohsiung.
