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.

It is better to do one's own duty, however defective it may be, than to follow the duty of another, however well one may perform it. He who does his duty as his own nature reveals it, never sins.

Returning to the source is stillness, which is the way of nature. The way of nature is unchanging. Knowing constancy is insight.

The wise man knows he doesn't know.

A good manager is best when people barely know that he exists. Not so good when people obey and acclaim him. Worse when they despise him.

Returning to the source is serenity.
