The Ancient Egyptians believed in many gods, and that every aspect of life in this world and the next was controlled by supernatural beings. The gods had to be appeased at all costs. The Deities represented the personification of order whilst the Demons were the forces of chaos. Temples were designed as power stations to maintain the fragile harmony of life. Only the Pharaoh or his representative, the high priest, could enter the most sacred areas for fear of upsetting the perfect balance of the universe. The living could appease both Deities and the Demons will spells and offerings and with the help of priests they could send and receive messages from the Netherworld.
