Here comes the sun
The Egyptians referred to Ra as “the Word”:
I am the Eternal, I am Ra
I am that which created the Word
I am the Word.
This passage comes from the Book of the Dead which is the oldest text in the world. Thousands of years later, this verse would reappear in the King James Bible:
In the beginning was the Word,
and the Word was with God,
and the Word was God.
Ra represents the third chakra or a masculine chord that can be used in meditation. This yellow, tetrahedral energy from the solar plexus can purify us from within. When we do this, we can begin to manifest our dreams. As the divine masculine, Ra embodies a shape that is not a circle but still uses π. This is the Reuleaux triangle (at centre below):

Like a headband with three twists in it, this surface has only one side and one boundary. The white lens in the middle is known as the Reuleaux triangle where all points on a side are equidistant from the opposite vertex. It also has the property of being unorientable:

Above: the serpentine musical chord of Ra
As the son of Isis, Ra was the king of all the other deities. Ra was so powerful that some have argued that the entire Egyptian religion was some form of veiled monotheism. This seems to be an overstatement, but it underlines Ra’s primary position within the religious texts as a facsimile of Atum. Below there is a golden serpent emerging from the vernal sun, symbolising rebirth:

In the Book of the Dead, the sun god Atum (Ra) was said to have ascended from the primordial waters as a snake. Atum was a self-created deity, the first being to emerge from the total darkness and watery abyss that existed before creation. A product of the energy within this chaos, he created his children (the Grand Ennead) out of loneliness.

This implied that the solar cult of Atum was all about order. The rising and setting of the Sun was linked with stability because it happened every day and therefore represented Ma’at—the guiding principle of the universe. It was also a symbol of the pharaoh, who embodied the “divine king” every morning when he rose like a snake.
