Yuthok Yonten Gonpo - The Younger - lived in the 12th Century, and is known as the Father of Tibetan Medicine. It is said that Yuthok The Younger left a legacy of ‘two jewels’, namely the Four Tantras (the Classic text on Tibetan Medicine) and Yuthok Nyingthig (a very important - and the most compact - spiritual practice for practitioners of Tibetan Medicine).
Yuthok The Younger predicted that ‘in the future, doctors would be so busy that they would have no time for spiritual practice’. So saying, he composed a very concise practice - the practice known as Yuthok Nyingthig, taught it to his one best student, and also passed onto him the transmission. This practice has subsequently been passed down from one generation of Tibetan doctors to the next, in an unbroken lineage.
