We measure the time by ourselves. Because we are limited within a hundred years, we count a hundred years, and a thousand years, and we cannot easily count much more. We cannot count the great cycles. When we are sad or sorry, the time goes so slowly. One moment seems an hour, and an hour seems a whole year. And when we are happy or joyful, the days pass so quickly, that ten years are gone, and we do not know where they are. This shows us that there is no time. The journey may take very, very many years, and yet it has not been a long time, because it was not felt to be long.
