Before an account of the process of mummification is given, it will be well to note briefly the views which the Egyptians held as to the relationship of the component parts of the material and spiritual man. Most peoples have divided man into three parts, =body=, =soul=, and =spirit=; but the Egyptian system of the human economy was more complex. The material part of a man was the =khat= 𓷓𓐳𓏏𓐎, or =body=. Through mummification, and the prayers which were recited over it after that process, the body obtained a degree of knowledge, and power, and glory, whereby it became henceforth lasting and incorruptible. This =glorified body= was called a =Sāḥu= 𓊃𓐰𓂝𓎛𓅱𓋩. When a man was born into the world there was also born with him an abstract individuality, or personality, which remained with him all the days of his life, and could only be separated permanently from him by death. To this personality is given the name =Ka= 𓂓𓐰𓏤, a word which has been translated by “double, genius, image, character, person, self,” etc. When the Ka left the body at death it was necessary for the living to find a habitation, and to provide meat, and drink, and shelter for it. Otherwise it would be obliged to wander about in search of food, and if it failed to find it, would return and wreak vengeance on the living. Provision was therefore made for the Ka in the tomb of the dead person of whom it had once formed a part. First a statue was made in stone, or wood, and fashioned to represent the deceased. Over this a long series of ceremonies was performed, and at the end of them the deceased was declared to have obtained the powers of talking, thinking, walking, etc., and the statue was supposed to be in a fit state to receive the Ka should it be pleased to enter into it and dwell there. A special chamber was set apart in the tomb for the statue, and through an opening in one of the walls which communicated with the hall of the tomb wherein the offerings were made, the Ka inhabiting this statue was able to enjoy the smell of the incense, meat, wine, and other offerings. It had power to leave the statue and to wander about at will on earth and in the Other World; and there are suggestions in the texts that it might take up its abode in the body of a living man from which his Ka had temporarily gone forth for some purpose of its own.
