That is when I understood the magical meaning of the circle. If you go away from a row, you can still come back into it. A row is an open formation. But a circle closes up, and if you go away from it, there is no way back. It is not by chance that the planets move in circles and that a rock coming loose from one of them goes inexorably away, carried off by centrifugal force. Like a meteorite broken off from a planet, I left the circle and have not yet stopped falling. Some people are granted their death as they are whirling around, and others are smashed at the end of their fall. And these others (I am one of them) always retain a kind of faint yearning for that lost ring dance, because we are all inhabitant of a universe where everything turns in circles.
