In the seventeenth century Desi Sangye Gyatso wrote the Blue Beryl, commissioned the seventy-nine medical paintings and founded the college at Chakpori. In 1916 the Men-Tsee-Khang was founded in Lhasa, and in 1961 refounded in Dharamsala. Sowa Rigpa is practised across the Himalaya and Mongolia, and was recognised as a system of medicine by India in 2010.
