Yutog Yontan Gonpo (12th century): the Physician King of Tibet. There are allegedly two Yutog Yontan Gonpos - referred to as the Elder and Younger. The existence of the Elder Yutog (8th century) has been questioned by many scholars over the centuries. The younger Yutog is the originator of the Yutog Nyingtig cycle of 'Revealed Treasure' teachings. It is most likely the case that all painted depictions, and sculpture, of Yutog Yontan Gonpo are depictions of the younger 12th century Yutog.
