The best soldiers are not warlike; the best fighters do not lose their temper. The greatest conquerors are those who overcome their enemies without strife. The greatest directors of men are those who yield place to others. This is called the Virtue of not striving, the capacity for directing mankind; this is being the compeer of Heaven. It was the highest goal of the ancients.

The Tao gives birth to One. One gives birth to Two. Two gives birth to Three. Three gives birth to all things. All things have their backs to the female and stand facing the male. When male and female combine, all things achieve harmony. Ordinary men hate solitude. But the Master makes use of it, embracing his aloneness, realizing he is one with the whole universe.
Because one believes in oneself, one doesn't try to convince. Because one is content with oneself, one doesn't need others' approval. Because one accepts oneself, the whole world accepts him or her.
