"The nature of god is a circle which the center is everywhere and the circumference is nowhere."
(Empedocles ancient Greek philosopher)
The circle was used as an ancient symbol to help explain the nature of god and the cosmos. Its configuration so impressed Michelangelo that he said, 'that an artist can claim perfection if he/she could draw, by free hand, a perfect circle.'
A diagram of a circle, in our case, symbolizes the boundless All; it also represents space. Within this boundless All resides all things that are and could be manifested. The sages. in an attempt to clarify the meaning of the boundless All, talked about it in terms of, "fullness." The possible permutations of manifestation are relatively infinite. To illustrate, lets take the case of our physical body, Scientists tells us that the bacteria alone number in the trillions, to say nothing of its cells, atoms, molecules, and sundry other manifested parts of our body. Now , what if we added all manifestations in our solar system and in our entire Universe, we have relatively infinite manifestation-fullness.
When Empedocles says that the center is everywhere, his meaning is that, even though the symbolic circle is marked, there is no real containment because the possible permutations of manifestation are relatively infinite. Thus the circumference is nowhere.
Now when Empedocles says that the center is everywhere, his meaning is that each unite of manifestation represents a point, a center, and since all possible permutations of manifestation are relatively infinite, all points/centers are everywhere.
