The sphere is a circle any way you look at it. It is the Universal circle, if you will: the True Divine Spirit. It symbolises nothing more and nothing less than complete emancipation from the material/physical world and material/physical law. It is to be so far beyond the four-fold world as to be inconcievable by us now, locked as we are in the physical. It is to be so divorced from the material as to not know anything of such existence.

Is it the Greater Oneness; Divinity; the Horizon of Eternity. It is God.
