"Ka" in the ancient Kemetic, or Egyptian language has a double meaning dealing with the spiritual, and the physical. Ka in the Kemetic language means the "vital energy of the soul", or the "soul". The Ka is often described simply as a "body double" which does not convey it's understanding as soul, or subtle vital energy. The Egyptian idea of a vital energy, Ka, is very much like "li" in Japanese, and "chi" in Chinese. Another definition of Ka in the Kemetic language is "body", or more precisely, "the dead, or empty body", as in the mummy.
"Ra", or "res" in the Kemetic language means "to wake up", "to rise up", "to keep awake", or "to watch". Ra is also the name given to the Sun (as in the Egyptian Sun God Ra) which re-news itself by circling to re-appear. In fact, you can find the prefix "re" in many words in the English dictionary that points to their Kemetic origins. "Why would Egyptian words show up in the English language?", you may wonder. This is because the early settlers of a European land revered the African/Egyptian symbol of the cross known as the Ankh. They named their land "Ankhland", which over time became "England".
"Te" or "t" in the Kemetic language means hand. In the ancient Kemetic writing system the symbol for "Te" is which means "out of, to go out; to emit; to give; to set; to place". Do not overlook the fact that the medu-neter (otherwise known as heiroglyph, a Greek term meaning "writings of the Gods") for "te" is an illustration of a hand, and that in Japanese the word "te" is also their word for hand.
