Those who defeat others are strong, those who defeat themselves are mighty.
He who knows, knows not. He who knows not, knows.
If Heaven and Earth are unable to persist, how could man?
The unyielding army will not win.
Goodie-goodies are the thieves of virtue.
Gentleness brings victory to him who attacks, and safety to him who defends. Those whom Heaven would save, it fences round with gentleness.
