Jsft is the concept of disorder and chaos in Ancient Egypt. It is contrasted with the concept Ma'at, truth, righteousness, and justice. The untraditional reign of Akhenaten was compared to Jsft, being replaced with tradition, Ma'at, by the Pharaoh Tutankhamen. The Ancient Egyptians viewed Jsft as a negative force in the world seeking to replace it with Ma'at.
