Is conformity, the first semblance of order in the universe and in our lives. This represents harmony for us and with it our sense of Justice. Without Symmetry there can be no Justice. Nothing runs so deeply in us than a sense of injustice.
The first principal is reflection. Not necessarily stereometry, for there is depth and height as well as breadth.
When an insects body is divided into 3 parts, each fulfilling a unique function, this is then reflected in the limbs, and it is here we find stereometry.
With the human the principal reflected is another prime number. Here though it is not three but five.
5 fingers, 5 toes, 5 sensory organs, 5 control organs, 5 internal breaths and 5 external breaths.
Then comes the stereometry, 2 hands, 2 eyes, 2 nostrils, 2 ears, 2 feet, 2 arms, 2 legs.
