The oldest religious texts suggest that the Egyptians always associated the Last Judgment with the weighing of the heart in a pair of scales, and in the illustrated papyri of the Book of the Dead great prominence is always given to the vignettes in which this weighing is being carried out. The heart, ab, was taken as the symbol of all the emotions, desires, and passions, both good and evil, and out of it proceeded the issues of life. It was intimately connected with the ka, i.e., the double or personality of a man, and several short spells in the Book PER-T EM HRU were composed to ensure its preservation (Chapters XXVI-XXXB*). The great Chapter of the Judgment of Osiris, the CXXVth, is divided into three parts, which are sometimes (as in the Papyrus of Ani) prefaced by a Hymn to Osiris. The first part contains the following, which was said by the deceased when he entered the Hall of Maati, in which Osiris sat in judgment: "Homage to thee, O Great God, Lord of Maati, [6] I have come to thee, O my Lord, that I may behold thy beneficence. I know thee, and I know thy name, and the names of the Forty-Two who live with thee in the Hall of Maati, who keep ward over sinners, and feed upon their blood on the day of estimating characters before Un-Nefer [7] ... Behold, I have come to thee, and I have brought maat (i.e., truth, integrity) to thee. I have destroyed sin for thee. I have not sinned against men. I have not oppressed [my] kinsfolk. I have done no wrong in the place of truth. I have not known worthless folk. I have not wrought evil. I have not defrauded the oppressed one of his goods. I have not done the things that the gods abominate. I have not vilified a servant to his master. I have not caused pain. I have not let any man hunger. I have made no one to weep. I have not committed murder. I have not commanded any to commit murder for me. I have inflicted pain on no man. I have not defrauded the temples of their oblations. I have not purloined the cakes of the gods. I have not stolen the offerings to the spirits (i.e., the dead). I have not committed fornication. I have not polluted myself in the holy places of the god of my city. I have not diminished from the bushel. I did not take from or add to the acre-measure. I did not encroach on the fields [of others]. I have not added to the weights of the scales. I have not misread the pointer of the scales. I have not taken milk from the mouths of children. I have not driven cattle from their pastures. I have not snared the birds of the gods. I have not caught fish with fish of their kind. I have not stopped water [when it should flow]. I have not cut the dam of a canal. I have not extinguished a fire when it should burn. I have not altered the times of the chosen meat offerings. I have not turned away the cattle [intended for] offerings. I have not repulsed the god at his appearances. I am pure. I am pure. I am pure. I am pure...."
