Dulduityn Danzanravjaa was a prominent Mongolian writer, composer, painter, Buddhist scholar, physician and the fifth Noyon Khutagt, the Lama of the Gobi. His name is a Mongolian adaptation of the last part of the Tibetan name Lobsang Tenzin Rabgye given to Danzanravjaa by the fourth Bogd Gegeen on his visit to the Mongolian capital, Urga, in 1812 – where Danzanravjaa was also recognized as an Incarnate Lama. There are several versions concerning the origins and use of "Dulduityn". He was the fifth incarnation of the Gobi Noyon Khutagt, which is the title of a prominent line of tulkus of the Nyingmapa lineage of Tibetan Buddhism in Mongolia and was found by the personal attendant of the fourth Noyon Khutagt in 1809. It was not possible to enthrone Danzanravjaa as the fifth Noyon Hutagt because of the ban from the ruling Manchu (Qing) dynasty on recognition of this line of incarnations. Mongolia at the time was under Manchurian Qing control. He was enthroned as the Avshaa Gegeen in Ongiin Gol Monastery by Ishdonilhudev Rinpoche. He is primarily famous for his poetry, but is also known for his prophecies, and treatises on medicine, philosophy, and astrology.
