Circle is life.
Expanding universe seen by our eyes, if only we had eyes big enough to see it. Dilatation of energy, creation coming towards us, or towards which we tend.
Passage, crossing, threshold, limit. The circle distinguishes what is from what is not, it is not yet or will not be: it cuts out or it welcomes inside, in perfect equidistance and harmony of form.
The dot in the middle of the circle is a circle.
