The circular nature of our existence. Sometimes life feels like a line. One long road. But I think it's true that it's really a circle, or an endless series of circles, strung out one after another. We are in a cycle. A cycle of cycles. We are carried along. There is a propulsive, forward movement, but the spinning, the endless spinning is at the heart of everything. I think it's good sometimes to take your hands off the wheel, and to watch it roll. It rolls with us and without us.
