Tao te Ching: 68

A skillful leader of troops is not oppressive with his military strength.
A skillful fighter does not become angry.
A skillful conqueror does not compete with people.
One who is skillful in using men puts himself below them.
This is called the virtue of not-competing.
This is called the strength to use men.
This is called matching heaven, the highest principle of old.

I have yet to find a version of the text that includes the phrase "of old" that thinks the phrase has significance here. Perhaps it was spuriously added, as Chan thinks. Perhaps there is still something to be gleaned from translation.

Notice how Lao Tzu follows again with the hierarchy (admittedly partially out of order) of action, from the individual to the small leader to the big leader. Much like he discussed with virtue in Chapter 54, the skill of the fighter is the skill of the leader which is the skill of the conqueror. And the conquerer must act as the sage and practice hsüan-te and follow wu wei or the world and the men will compete with him and eventually, the conqueror will lose.
