Rigdzin Tsewang Norbu

Katok Rigdzin Tsewang Norbu (, 1698–1755) was a teacher of the Nyingma school of Tibetan Buddhism who notably championed the shentong or "empty of other" view first popularised by the Jonang school. He also examined the Chan Buddhist teachings of Hashang Mahayana, known as Moheyan. Despite the shentong view being banned as heretical, he successfully taught and cultivated its teachings as a legitimate view of the Nyingma school.

Sonam Deutsen offered to enthrone Rigdzin Tsewang Norbu, when he was 24 years of age, as the Rinpoche of Katok Monastery, but he declined and said he preferred his life as a "vagabond". His seat remained at the Katok Monastery of Tibet.

Scholarly impact Katok Tsewang Norbu's interests spanned many of the important Nyingma and Kagyu teachings of Tibetan Buddhism, and Bon, including several not associated with the Nyingma schools: Katog Tsewang Norbu (1698-1755) was the head of Katog monastery, and ranks as one of the most impressive scholars of eighteenth-century Tibet. His studies took in both the texts of the Nyingma and those of the new schools; he exchanged Nyingma for Kagyü teachings with the Twelfth Karmapa, Jangchub Dorjé (1703-1732), and wrote a history of the transmission of Mahāmudrā. Tsewang Norbu studied and championed the forbidden Jonang doctrines, writing several works on the "empty of other" (gzhan stong) theory and on the Kālacakra tantra, the source of "empty of other" in the tantric corpus. He also wrote some non-religious works on history and geography and travelled widely, making several journeys to Nepal. This revival was continued by Jamgon Kongtrul, a 19th-century Rimé movement scholar and a teacher of shentong. More recently, the Kagyu Rinpoches Kalu Rinpoche and Khenpo Tsultrim Gyamtso Rinpoche also taught the shentong view.
