“The art of war teaches us to rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him.”

If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him.

Know thy self, know thy enemy. A thousand battles, a thousand victories.

He who is prudent and lies in wait for an enemy who is not, will be victorious.

Appear weak when you are strong, and strong when you are weak.

All warfare is based on deception.

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

To know your enemy, you must become your enemy.
