Mongolian historians divide the spread out Buddhism in Mongolia three periods: The first period of Hun empire, the second period of the Mongol empire and third period from XVI century onwards. From the XVI century Mongols translated the numerous Buddhist moral doctrines: “Subashid”, “Eulogies of Paramita”, “The Stages of the path to enlightenment”, “Shastra of wood”, “Sahstra of water”, “Songs of the world of vessel and contents”, “Lamp for the path to enlightenment”, “A drop of Nourishment for People” of Nagarjuna, (...) etc. Therefore, ethical doctrine occupies an important place in Mongolian Buddhism. Mongol scholars made their own commentaries and took as an example the works of Indian and Tibetan great scholars who created their own ethical doctrines. An influence on Buddhist rituals and theology via Buddhist ethical doctrines was spread among the nobles and the ordinary people. The late Academician Ch. Jugder saw the period from the 16th to 18th centuries as important period for Buddhism in Mongolia. It permeated in nomadic way of life and national customs. Especially, Madhyamaka prasangika philosophy was developed, while Mongolian Buddhist philosophical works started from the first Mongolian Bogdo Lama Undur Gegeen Zanabazar’s works. Mongol thinkers contributed greatly in the development of Buddhist ethics. (shrink)
