Anubis, the god of the dead, assisted the deceased at the judgement where the latter's heart was weighed against a feather.  After the deceased has passed the test he was considered "justified" and "transfigured" which gave him access to the fields od Aaru. The alternative was to be devoured by Ammit "devoured of the dead", a monster part crocodile, part big cat and part hippopotamus.
