Buddhism and Shamanism (or more specifically, Tengerism) have had a very uneasy relationship in Mongolia. Tibetan Buddhism was brought to Mongolia by a crafty ruler or “khan,” who couldn't unite the Mongolian tribes under his banner because he was not a bloodline descendant of the mighty Genghis. He made a deal with a Tibetan lama to declare him a reincarnation of Genghis's grandson Kublai, thus allowing him to seize power. In return, he recognized the lama as the “ocean teacher,” a phrase indicating supreme authority. That phrase, in Mongolian, is “Dalai Lama,” so the institution of Dalai Lama was directly connected with Mongolian power politics.
