Ab, or heart, is the physical reed organ called hat as a material corporate entity and ab as a spiritual body. The heart was taken the seat of reason, faith, and effect by the Egyptians and was commonly left in the body during mummification. A heart scarab was involved in the wrappings because the heart showed at the judgment halls of osiris. The heart was weighed there against a feather of the goddess Maat to ensure the worthiness of the deceased. Heart Amulets were contemporary in the New Kingdom (1550-1070 B.C.E.) and were designed out of carnelian or glass.
