What enables the wise sovereign and the good general to strike and conquer, and achieve things beyond the reach of ordinary men, is foreknowledge.

What is of supreme importance in war is to attack the enemy's strategy.

He who knows things, and in fighting puts his knowledge into practice, will win his battles. He who knows them not, nor practices them, will surely be defeated.

War is a matter of vital importance to the state.

If you know both yourself and your enemy, you can win a hundred battles without a single loss.

It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.

Go into emptiness, strike voids, bypass what he defends hit him where he does not expect you.
