What is the scale that is used for weighing the heart through the afterlife?

In ancient Egyptian mythology, the scale used for weighing the heart in the afterlife is called the "Scales of Ma'at." During the judgment of the dead, the deceased's heart was placed on one side of the scale, while a feather representing truth and justice, associated with the goddess Ma'at, was placed on the other. If the heart was lighter than the feather, the individual was deemed worthy and allowed to enter the afterlife; if heavier, they faced dire consequences.
