The ultimate skill is to take up a position where you are formless. If you are formless, the most penetrating spies will not be able to discern you, nor the wisest counsels be able to do calculations against you. Therefore, your strategy for victories in battle is not repititious, and your formations in response to the enemy are endless. Those who are able to adapt and change in accord with the enemy and achieve victory are called divine.

-Sun Tzu
