Shamanic lore
Gongsu (The Spirit's Words)
Words believed to be delivered by a spirit through a shaman's mouth during a gut or reading. Its mark is a plain, casual tone conveying an oracle or the words of the dead.
Sinnaerim (Spirit Descent)
The shamanic idea that a spirit settles into a chosen person, opening the path to becoming a shaman. It is told alongside mubyeong, an unexplained affliction, and the naerim-gut that resolves it.
