Cheonji-wang, the King of Heaven and Earth, opens the Cheonji-wang bon-puri, the origin chant sung at the outset of the great Jeju kut to establish the order of the cosmos. In the beginning sky and earth were fused; when they parted, two suns and two moons scorched and froze the world by turns. Cheonji-wang descends to the human realm, where he punishes the arrogant tyrant Sumyeong-jangja with fire and lightning, and lies one night with the earthly woman Chongmyeong-buin. Departing, he gives her gourd seeds and foretells the birth of twin sons. Those sons, Daebyeol-wang and Sobyeol-wang, later climb the gourd vines to his heavenly court, where he sets them the contests that divide the worlds of the living and the dead.
