Coming Full Circle in Blue Highways

On his travel diary "Blue Highway", William Least Heat Moon travels to various worthy destinations. His American expedition is characterized by a pattern of travel along the circle. Least Heat Moon's circulation trip is both text and spirit. He traveled throughout the country and gathered history and personality from all over the United States. However, more importantly, Least Heat Moon searched for and discovered itself. "Even if you trace a circle it does not become a goal, but neither line," he briefly explained the cyclical nature of his journey.

This life is not like a line but a circle. We will not go up to the sky, we can not find more love, touch, trust, intimacy. We rotate around this circle, thinking that we are rising, we will complete the circle once more and understand the other direction. So why do you think people are rising too far or too high? Humility, humus, earth. I only do small things with dust. Do not make me think, I have to do anything

Let's put this argument into the yen (laugh). Each raindrop shines like a circle. And in the right environment, the rainbow appears to go around. However, although these are two very different circles, they all contain an angle of 41 degrees. For each raindrop that forms a 41 degree angle between you and the sun, you can see only one color and you only see the smallest strip of complete circle of color emanating from the drop can do. The arc of the rainbow you actually see is due to the convergence of the light above your eyes, a small sample of colored light emerging from countless droplets. In contrast, rainbow-colored light from each waterdrop diverges in multiple directions. No one can see this direction. Literally, the rainbow is far beyond my eyes.
