If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected .”

“If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.”

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

“All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear 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.”

“Deep knowledge is to be aware of disturbance before disturbance, to be aware of danger before danger, to be aware of destruction before destruction, to be aware of calamity before calamity. Strong action is training the body without being burdened by the body, exercising the mind without being used by the mind, working in the world without being affected by the world, carrying out tasks without being obstructed by tasks.”
