Dr. Nida Chenagtsang

Dr. Nida Chenagtsang trained extensively in Sowa Rigpa, traditional Tibetan medicine, and now leads Sorig Khang International, a global network teaching medical theory and practice, kunyé massage and external therapies, Tibetan astrology, and the Yuthok Nyingthig — a Nyingma system of tantric practice that includes dream yoga, Lüjong (a subtle-body movement practice), and Karmamudra, a tantric consort practice from the Yuthok Nyingthig cycle. He is explicit in his own writing that sexual misconduct by teachers is a real problem within the wider Tibetan Buddhist world, and has written to clarify common misconceptions about these tantric practices.

He teaches internationally across some 40 countries through public talks, workshops and structured tenure courses, mostly conducted in English. No web search turned up any allegation naming him personally; the point above about misconduct in the field is his own commentary on the broader landscape, not a claim against him.
