The Kei are primarily ethnic religionists, practicing their ancient traditions and religions. An important element in their religion is the belief in spirits of the dead. The spirits of those who died a violent death or of women who died in childbirth are especially feared. Mythology also speaks of Duan Lerwuan, the god of the sun, and of Duan Luteh, the god of the moon. Other Kei deities include Hejan Suwat, the god of the sea, and Lir Majoran, the god of agriculture.
