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.
Arms are instruments of ill omen.... When one is compelled to use them, it is best to do so without relish. There is no glory in victory, and to glorify it despite this is to exult in the killing of men.... When great numbers of people are killed, one should weep over them with sorrow. When victorious in war, one should observe mourning rites.
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.
When the people of the world all know beauty as beauty, There arises the recognition of ugliness. When they all know the good as good, There arises the recognition of evil.
