The "Chogong bon-puri" is a shamanic narrative whose recitation forms the tenth ritual of the Great "Gut", the most sacred sequence of rituals in Jeju shamanism. The "Chogong bon-puri" is the origin myth of Jeju shamanic religion as a whole, to the point that shamans honor the myth as the "root of the gods" and respond that "it was done that way in the "Chogong bon-puri"" when asked about the origin of a certain ritual. It also explains the origin of the "mengdu", the sacred metal objects that are the source of a Jeju shaman's authority. As with most works of oral literature, multiple versions of the narrative exist. The summary given below is based on the version recited by the high-ranking shaman An Sa-in (1912—1990).
