Mahasiddha Yoga
A Tantra and yoga school in Chiang Mai, and the ashram it built to teach in. Founded by Uriel Yariv and Blandine Wegener, who are both psychologists as well as teachers, and who wrote the four courses the school is known for: the Tantra Immersion, the Emotional Healing Course, the Path to Purpose programme and the Lucid Dreaming Course. The Tantra Immersion runs in four levels and people come back for the next one, which is the most useful thing you can know about a school. Residential work happens at Amrita Integral Yoga Centre, twenty five minutes east of the old city in San Kamphaeng, purpose-built on sacred architecture principles with a wooden practice hall, a garden, a pool, and rooms for about forty. They also run silent meditation retreats over New Year, women's circles, and a full online catalogue. The teaching is esoteric Tantra in the classical sense rather than the workshop sense: chakra by chakra, with lectures, and with the couples and continence material taught openly as part of the tradition.
