All warfare is based on deception. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

Do not swallow bait offered by the enemy. Do not interfere with an army that is returning home.

Every battle is won before it is fought.

Subtle and insubstantial, the expert leaves no trace; divinely mysterious, he is inaudible. Thus he is master of his enemy's fate.

What is of the greatest importance in war is extraordinary speed: One cannot afford to neglect opportunity.

When the enemy is relaxed, make them toil. When full, starve them. When settled, make them move.

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