Genghis Khan (also known as Chinggis Khan) lost his battle against the Merkit (one of the major tribal confederations (khanlig) of the Mongols) and escaped death by seeking protection in the sacred precincts of the Burkhan Khaldun mountains. An old woman saved him and a few others. As mark of great reverence to the mountain, which in Mongolia is considered a highly sacred mountain of spiritual significance, and to the sun above, he offered his respects to the spirits of the mountain around him, sprayed milk into the air and sprinkled it on the earth. He removed his girdle strap, unwinding it from his outfit, and then put it around his neck.
