WHAT IS "KA"?

The god Knemu who was said to create each man out of clay on his potter's wheel also molded the Ka at the same time. His name comes from the root force of the term "Khnem" meaning "To Built."
Knemu was the building powerful force, which built the first symbolic egg from which the sun sprang.
The same force also made possible the existence of other forces that the Egyptians deified them as gods,  and sculpted the first man on a potter's wheel and he continue to build up their bodies and maintain their life. He built up (architect) the material universe with Ptah, thinking (mind) and saying (words) their names with the tongue, under the guidance and direction of Thoth (Wisdom). They were unique because their methods were intellectual rather than physical. According to the priests of Memphis, where Ptah was their god, they said that everything was the work of Ptah's heart and tongue: gods were born, town were founded, and order was maintained. Ptah was the patron of skilled craftsmen and architects, while Thoth was the patron of philosophy and wisdom.
Knemu, as the architec, had 7 forms: -The creator (Knemu-Nehep). -The governor of 2 lands (Knemu-Kenti-Taui). -The weaver of his light (Knemu-Sekhet-Ashsep-f). -The governor of the house of life (Knemu-Kenti-Per-Ankh). Lord of the land of life (Knemu-Neb-Ta-Ankhtet). The governor of the house of sweet life (Knemu-Kenti-Netchemtchem-Ankhet. -Lord (Knemu-Neb).
Knemu was one of the oldest gods of Egypt, and the views of him changed somewhat through its history. He was worshiped from Thebes to Philae, but the principal sanctuaries were at the First Cataract (Elephantine and Philae).
Knemu was originally a water-god, and as such he is shown with water flowing over his outstretched hands and wearing a jug on his head above his horns. His symbol was the flat-horned Ram and was depicted as a Ram-headed man who wears the White Crown on his head.
He always was an important force and it remained as that even in some semi-Christian groups 2 to 3 centuries after the birth of Christ Jesus!
Ka in appearance was portrayed by the Egyptians in several ways: -A person identical to the person whom it was associated with. -As a shadowy figure. -As a person with two upraised arms on his head.
Ka in meaning had a very complex symbolism and represent: -the reception of the life power received from supernatural beings. -The representation itself of the life power. The spiritual double that resides with every human being.
The Egyptian hieroglyphic representation for "Ka" was the shoulders and arms with the arms bent upwards at the elbow.
Ka as a spiritual double was born with every human being and lived on as long as it had a place to live, regardless the life of the corporeal vessel. While the individual was alive Ka lived within the body as an acting life force in the physical body. Then after the person died, Ka still needed to be connected to the corporeal vessel in order to complete its journey in the afterlife and enter into the eternal existence as long as it passed the judgment of Maat. New bodies were assigned and new levels of existence were achieved. This is why the Egyptians mummified their dead. If the body decomposed before achieving the final destination, then the spiritual double would die and the deceased would lose their chance for eternal life, being trapped in a cavern in the Underworld waiting for a chance to come back and be assigned to a new vessel, without the knowledge of its previous life.
An Egyptian euphemism for death was "going to one's Ka." After death Ka became supreme. Kings thus claimed to have multiple "Kas". Rameses II announced that he had over 20.
When Ka acted according to the universal law and order, all was well, both spiritually and materially. Sin was called "an abomination of the Ka." The Ka was seen as the natural instinct or conscience of each individual, urging kindness, quietude, honor and compassion. In images and statues of the Ka, these qualities are depicted as their owner in an idealized and desirable state of youth, strength, and beauty, seeing Ka as the origin and giver of life to all.
Ka resided in the gods as well. Egyptians often placated the "Kas" of the deities in order to receive favors. The divine "Kas" also served as guardians. Osiris was often called the Ka of the Pyramids.
