"삼신" refers to the three deities in Korean mythology known as the "Three Gods" or "Three Spirits." These deities are often associated with fertility, childbirth, and the protection of families. In traditional Korean culture, they are revered during pregnancy and childbirth, with rituals performed to seek their blessings for a safe delivery and healthy offspring. The three deities are typically identified as 삼신할머니 (Grandmother Samshin), 삼신할아버지 (Grandfather Samshin), and 삼신 (the third spirit). 삼신할머니 is the most well-known and is often depicted as a nurturing figure. Families may create altars or perform ceremonies to honor these deities, reflecting the importance of fertility and family in Korean society.
