At Nitartha Institute, Western faculty, translators, and students from around the world closely study core texts and commentaries with Tibetan masters. Joining the wisdom and scholarship of the East with Western scholarship and ways of inquiry, the quality of awakening intelligence is advanced.

Dzogchen Ponlop Rinpoche founded Nitartha Institute under the guidance of Khenchen Thrangu Rinpoche and Khenpo Tsultrim Gyamtso Rinpoche, two of the leading contemporary teachers of the Karma Kagyü and Nyingma traditions of Tibetan Buddhism. Dzogchen Ponlop Rinpoche and Acharya Lama Tenpa Gyaltsen share the primary leadership and teaching responsibilities at Nitartha by designing the curriculum and by teaching the principal courses at the Summer Institute. Rinpoche and Acharya graduated with high honors from the nine-year training program at Karma Shri Nalanda Institute at Rumtek, Sikkim, India (an affiliate of the Sanskrit University of Varanassi).

Visiting Acharyas, also graduates of Karma Shri Nalanda Institute, often teach in the foundation, intermediate, and advanced programs at the Summer Institute. Visiting Acharayas have included Acharya Kelsang Wangdi, Acharya Sherab Gyaltsen Negi, and Acharya Tashi Wangchuk. The principal faculty are assisted by Western faculty, senior students, and translators. The faculty vary at any particular session of Nitartha Institute (summer or regional).

Excellent instruction by enthusiastic, kind, patient and knowledgeable instructors. I liked the availability of all the teachers.”
