Bai-Ülgen lives on the sixteenth floor of the sky above the stars, sun and moon in a golden house. Mere humans may never reach him, excepting shamans or kams, who possess astral powers. Animals are used for sacrifice in worship of him, especially horses. Once in every third, sixth, ninth, or twelfth year, a shaman may sacrifice a white horse as the first step of reaching Ülgen. Then he must ride its soul, penetrate through all the layers of heaven until he reaches Ülgen. Firstly, the kam (shaman) meets Yayık who is the servant of Ülgen. This entity informs the kam whether or not the offering has been accepted. If the sacrificial rite has been successful, the shaman is able to learn from the omniscient Ülgen of impending dangers, such as bad harvests.
