In ancient Egypt, the eternal judge of souls is Osiris, who presides over the judgment of the deceased in the afterlife. Osiris evaluates the hearts of the dead against the feather of Maat, the goddess of truth and justice. This judgment determines whether a soul may enter the Field of Reeds or face eternal punishment. The significance of Osiris lies in his role as a protector of the dead and as a symbol of resurrection, embodying the Egyptian belief in rebirth and the cyclical nature of life and death.
