War is a matter of vital importance to the state.

Humble words and increased preparations are signs that the enemy is about to advance. Violent language and driving forward as if to the attack are signs that he will retreat.

If the mind is willing, the flesh could go on and on without many things.

In desperate position, you must fight.

In warfare, there are no constant conditions. He who can modify his tactics in relation to his opponent will succeed and win.

To capture the enemy's entire army is better than to destroy it; to take intact a regiment, a company, or a squad is better than to destroy them. For to win one hundred victories in one hundred battles is not the supreme of excellence. To subdue the enemy without fighting is the supreme excellence.

The best general is the one who never fights.
