In Egyptian mythology, the concept of maat represents truth, balance, and cosmic order. It is a fundamental principle guiding the universe, ensuring that everything maintains its rightful place. Maat is personified as a goddess who plays a crucial role in the afterlife, where the deceased's heart is weighed against her feather of truth in the Weighing of the Heart ceremony. Living in accordance with maat is essential for maintaining harmony in both personal and societal aspects, reflecting ethical living and justice. It is a central tenet in ancient Egyptian spirituality.
