"죽은 자의 세계" (The World of the Dead) refers to the concept of an afterlife or realm where souls go after death in various cultures. This idea often includes beliefs about judgment, reincarnation, or eternal rest, depending on the specific traditions and religions involved. In Korean culture, the concept is influenced by Buddhism and Shamanism, which emphasize the importance of honoring ancestors and the spiritual journey of the deceased. Rituals and ceremonies, such as Chuseok and Jesa, are performed to pay respect and ensure the well-being of those who have passed away.
