It was the Ka, therefore, which in the early days of Egyptian religious thought was more especially associated with the divine nature of the king. The association of ideas was assisted by the fact that the gods, like men, had each his individual Ka. And in the older period of Egyptian history the Ka of the god and not the god himself was primarily the object of worship. The sacred name of Memphis was Ḥa-ka-Ptaḥ, “the temple of the Ka of Ptaḥ,” which appears as _Khikuptakh_ in the Tel el-Amarna letters, and from which the Greeks derived their _Aiguptos_, “Egypt.” Even in the last centuries of Egyptian independence the prayers addressed to the bull-god Apis are still made for the most part to his Ka. The Ka, in fact, was conceived of as the living principle which inspired both gods and men. Its separation from the body meant what we call death, and life could return only when the two were reunited. That reunion could take place only in the other world, after long years had passed and strange experiences had been undergone by the disembodied Ka. The 105th chapter of the Book of the Dead contains the words with which on the day of resurrection the Ka was to be greeted. “Hail,” says the dead man, “to thee who wast my Ka during life! Behold, I come unto thee, I arise resplendent, I labour, I am strong, I am hale, I bring grains of incense, I am purified thereby, and I thereby purify that which goeth forth from thee.” Then follow the magical words by which all evil was to be warded off: “I am that amulet of green felspar, the necklace of the god Ra, which is given unto them that are on the horizon. They flourish, I flourish, my Ka flourishes even as they, my duration of life flourishes even as they, my Ka has abundance of food even as they. The scale of the balance rises, Truth rises high unto the nose of the god Ra on the day on which my Ka is where I am (?). My head and my arm are restored to me where I am (?). I am he whose eye seeth, whose ears hear; I am not a beast of sacrifice. The sacrificial formulæ for the higher ones of heaven are recited where I am.” As might be expected, the Ka is often represented with the symbol of life in its hands. At the same time, it is important to remember that, though under one aspect the Ka was identical with the principle of life, in the mind of the Egyptian it was separate from the latter, just as it was separate from consciousness and from the divine essence. These were each of them independent entities which were possessed by the Ka just as they were possessed by its human counterpart. Life, consciousness, and relationship to the gods were all attributes of the Ka, but they were attributes, each of which had a concrete and independent existence of its own.
