Spiritual Bearing in Strategy

In strategy your spiritual bearing must not be any different from normal. In normal times, and in times of combat, try to be no different: Keep your mind broad and straight; do not stretch it taut; do not allow it to grow in the least lax; do not make it lean to one side but hold it at the center; keep it quietly fluid, doing your best to maintain it in a fluid state even while it is fluid.

When you are quiet, your mind shouldn't be quiet; when you are moving fast, your mind shouldn't at all be moving fast. Even when your mind is calm do not let your body relax, and when your body is relaxed do not let your mind slacken. Do not let your spirit be influenced by your body, nor your body be influenced by your spirit. Your mind should lack nothing while having no excess. An elevated spirit is weak and a low spirit is weak. Superficially you may have your mind appear weak, but you must keep it strong inwardly, lest people can tell what you really are. Do not let the enemy see your spirit.

If you have a small body, you must know whatever there is to know about having a large body; if you have a large body, you must know all about having a small body. Whatever your size, you must keep your mind straight and not be misled by knowing only your own body. With your spirit open and un-constricted, look at things from a high point of view. You must cultivate your wisdom and spirit. Polish your wisdom: learn public justice, learn to distinguish between right and wrong, study the Ways of different arts one by one to experience what is sought in each. When you cannot be deceived by anyone you will have acquired judgment in strategy.

The wisdom of strategy is different from other things. On the battlefield, even when you are hard-pressed, you should ceaselessly research the principles of strategy so that you can develop a steady spirit.
