Yuthok Yonten Gonpo the younger (1126-1202) was a Traditional Tibetan doctor credited with composing the Four Medical Tantras (rGyud-bZhi), a four book treatise on Traditional Tibetan medicine which forms the main course of study in the Tibetan Medical tradition. He is widely regarded as the main founder of Tibetan Medicine, mostly based on his composition of the Four Medical Tantras. His other important contribution to Tibetan culture was the Yuthok Nyingthik which is the main Tantric Buddhist practice cycle associated with Tibetan Medicine. It is traditionally considered to be an important spiritual component of healing in Tibetan medical culture, and moreover is regarded in all Tibetan Buddhist traditions as a very special method for attaining awakening and realization quickly.
