He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
LaoziTo be brave without compassion, generous without moderation, and rule without refraining from being first in the world, are certain deaths.
LaoziArms 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.
Laozi
