Ma'at - Egyptian Mythology

Ma'at was the Egyptian goddess for truth and divine order. She was said to have come into existence the moment Ra, the creator god emerged from the lotus. One of the more abstract Egyptian gods, she was also one of the most integral to their religion and society. When someone died, their heart was weighed by Anubis against the feather of Ma'at, to determine if they had lived a good life. If the heart was as light as the feather, they could move on to the afterlife and become one of the blessed living. If not, their heart would be fed to Ammut and they would be truly dead.
