He saw the moon low in the sky now. The moon there, and the light of the moon caused by what? By the sun, of course. And what lights the sun? Its own fire. And the sun goes on, day after day, burning and burning. The sun and time. The sun and time burning. Burning. The river bobbled him along gently. Burning. The sun and every clock on the earth. It all came together and became a single thing in his mind. After a long time of floating on tea land and a short time of floating in the river he knew why he must never burn again in his life.
