The Tao is great. The universe is great. Earth is great. Man is great. These are the four great powers. Man follows the earth. Earth follows the universe. The universe follows the Tao. The Tao follows only itself.
But the whole vital process of the earth takes place so gradually and in periods of time which are so immense compared with the length of our life, that these changes are not observed, and before their course can be recorded from beginning to end whole nations perish and are destroyed.
