In Korean shamanism, the Chogong bon-puri (Korean: 초공본풀이) is a shamanic narrative whose recitation forms the tenth ritual of the Great Gut, the most sacred sequence of rituals in Jeju shamanism.[1] 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.[2] It also explains the origin of the mengdu, the sacred metal objects that are the source of a Jeju shaman's authority.[1] As with most works of oral literature, multiple versions of the narrative exist.[3] The summary given below is based on the version recited by the high-ranking shaman An Sa-in (1912–1990).[4]
