It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.

A leader leads by example not by force.

Secret operations are essential in war; upon them the army relies to make its every move.

The supreme art of war is to subdue the enemy without fighting.

And therefore those skilled in war bring the enemy to the field of battle and are not brought there by him.

The expert in battle seeks his victory from strategic advantage and does not demand it from his men.

In executing an Artful Strategy: When ten times greater, surround them; When five times greater, attack them; When two times greater, scatter them. If the opponent is ready to challenge: When fewer in number, be ready to evade them; When unequal to the match, be ready to avoid them. Even when the smaller opponents have a strong position, the larger opponent will capture them.
