In Egyptian mythology, Ammit (also spelt Ammut, Ammet, Amam, Amemet an Ahemait) was the personification of divine retribution for all the wrongs one had committed in life and she dwelt in the Hall of Ma'at. Ammit was said to live near the scales of justice, in the underworld, Duat, where the hearts of the dead were weighed by Anubis against the feather in Ma'at's headdress. Ma'at was regarded as the personification of the principles of truth and justice. The hearts of those who failed the test were given to Ammit for her to devour, and their souls were not permitted to enter Aaru, having to be restless forever—dying a second time.
