What did t mean if the heart was lighter than the feather?

In ancient Egyptian mythology, if a person's heart was lighter than a feather during the judgment of the dead, it signified that they had led a virtuous life and were deemed worthy of entering the afterlife. The feather represented Ma'at, the goddess of truth and justice. A heart heavier than the feather indicated a life filled with sins and wrongdoings, resulting in punishment or a negative fate in the afterlife. This judgment was a central aspect of the Egyptian belief system regarding morality and the afterlife.
