The Ni To Ichi Way of strategy is recorded in this the Book of the Void. - Miyamoto Musashi

Knowing the Way of the long sword means we can wield with two fingers the sword that we usually carry. If we know the path of the sword well, we can wield it easily. If you try to wield the long sword quickly you will mistake the Way. To wield the long sword well you must wield it calmly. If you try to wield it quickly, like a folding fan or a short sword, you will err by using "short sword chopping". You cannot cut a man with a long sword using this method.

If you do not look at things on a large scale it will be difficult for you to master strategy. If you learn and attain this strategy you will never lose even to twenty or thirty enemies. More than anything to start with you must set your heart on strategy and earnestly stick to the Way. You will come to be able to actually beat men in fights, and to be able to win with your eye. Also by training you will be able to freely control your own body, conquer men with your body, and with sufficient training you will be able to beat ten men with your spirit.

When your opponent is hurrying recklessly, you must act contrarily and keep calm. You must not be influenced by the opponent. Train diligently to attain this spirit.
