Every man on the Day of Judgment will take on a “characteristic form”, a particular form with specific characteristics, which will be proportional to “the qualities of evil or virtue”, will be proportional to the ethos, actions, and dispositions of each man. This is also the case in this life, since every man, depending on his actions, forms in his soul a particular character, which is usually expressed in the manifestations of his face; thus, we can easily distinguish the angry, the melancholic, the meek, or the cheerful man. Just as now man takes a form which is the fruit of the inner disposition of his soul, so in the same way on the day of judgment every man will assume a particular form, which will reveal the abundance and the magnitude of his virtues or vices, the quality of his actions and the moods of his soul. So, what he exactly is, can be seen.
