吾士无余财，非恶货也。无余命，非恶寿也。(If our soldiers are not overburdened with money, it is not because they have a distaste for riches; if their lives are not unduly long, it is not because they are disinclined to longevity.)
故善战者，求之于势，不责于人。(The expert in battle seeks his victory from strategic advantage and does not demand it from his men.)
Be extremely subtle even to the point of formlessness. Be extremely mysterious even to the point of soundlessness. Thereby you can be the director of the opponent s fate.
Knowing the enemy enables you to take the offensive, knowing yourself enables you to stand on the defensive.
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.
When one treats people with benevolence, justice, and righteousness, and reposes confidence in them, the army will be united in mind and all will be happy to serve their leaders.
