“All warfare is based on deception.”

“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.”

“If you know the enemy and know yourself, you need not fear the result of a hundred battles.”

“To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy’s resistance without fighting.”
