"Whatever I fight weakens me. What I cooperate with strengthens me."
A good soldier is not violent. A good fighter is not angry. Good winners do not contend. Good employers serve their workers. The best leader follows the will of the people.
All of them embody the virtue of non-competition. This is called the virtue of noncontending. This is called employing the powers of others.
This since ancient times has been known as the ultimate unity with heaven.
