What is "eopsin"

Eopsin is the goddess of the storage and wealth in Korean mythology and shamanism. She is one of the Gasin, or deities that protect the house. However, unlike other Gasin, who were believed to embody pots, paper, and other inanimate objects, Eopsin is special in that she appears in an animal form. This is because Koreans considered snakes and weasels, who ate mice and rats, holy.
