Just as a horse must have endurance and no defects, so it is with weapons. Horses should walk strongly, and swords and companion swords should cut strongly. Spears and halberds must stand up to heavy use: bows and guns must be sturdy. Weapons should be hardy rather than decorative.
You should not have a favourite weapon. To become over-familiar with one weapon is as much a fault as not knowing it sufficiently well. You should not copy others, but use weapons which you can handle properly. It is bad for commanders and troopers to have likes and dislikes. These are things you must learn thoroughly.
Timing in strategy
There is timing in everything. Timing in strategy cannot be mastered without a great deal of practice.
Timing is important in dancing and pipe or string music, for they are in rhythm only if timing is good. Timing and rhythm are also involved in the military arts, shooting bows and guns, and riding horses. In all skills and abilities there is timing.
There is also timing in the Void.
There is timing in the whole life of the warrior, in his thriving and declining, in his harmony and discord. Similarly, there is timing in the Way of the merchant, in the rise and fall of capital. All things entail rising and falling timing. You must be able to discern this. In strategy there are various timing considerations. From the outset you must know the applicable timing and the inapplicable timing, and from among the large and small things and the fast and slow timings find the relevant timing, first seeing the distance timing and the background timing. This is the main thing in strategy. It is especially important to know the background timing, otherwise your strategy will become uncertain.
You win battles with the timing in the Void born of the timing of cunning by knowing the enemies' timing, and thus using a timing which the enemy does not expect.
All the five books are chiefly concerned with timing. You must train sufficiently to appreciate this.
If you practise day and night in the above Ichi school strategy, your spirit will naturally broaden. Thus is large scale strategy and the strategy of hand to hand combat propagated in the world. This is recorded for the first time in the five books of Ground, Water, Fire, Tradition (Wind), and Void. This is the way for men who want to learn my strategy:
Do not think dishonestly. The Way is in training. Become acquainted with every art. Know the Ways of all professions. Distinguish between gain and loss in worldly matters. Develop intuitive judgement and understanding for everything. Perceive those things which cannot be seen. Pay attention even to trifles. Do nothing which is of no use.
It is important to start by setting these broad principles in your heart, and train in the Way of strategy. 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 you have reached this point, will it not mean that you are invincible?
Moreover, in large scale strategy the superior man will manage many subordinates dextrously, bear himself correctly, govern the country and foster the people, thus preserving the ruler's discipline. If there is a Way involving the spirit of not being defeated, to help oneself and gain honour, it is the Way of strategy.
The spirit of the Ni Ten Ichi school of strategy is based on water, and this Water Book explains methods of victory as the long-sword form of the Ichi school. Language does not extend to explaining the Way in detail, but it can be grasped intuitively. Study this book; read a word then ponder on it. If you interpret the meaning loosely you will mistake the Way.
The principles of strategy are written down here in terms of single combat, but you must think broadly so that you attain an understanding for ten-thousand-a-side battles.
Strategy is different from other things in that if you mistake the Way even a little you will become bewildered and fall into bad ways.
If you merely read this book you will not reach the Way of strategy. Absorb the things written in this book. Do not just read, memorise or imitate, but so that you realise the principle from within your own heart study hard to absord these things into your body.
Spiritual Bearing in Strategy
In strategy your spiritual bearing must not be any different from normal. Both in fighting and in everyday life you should be determined though calm. Meet the situation without tenseness yet not recklessly, your spirit settled yet unbiased. Even when your spirit is calm do not let your body relax, and when your body is relaxed do not let your spirit slacken. Do not let your spirit be influenced by your body, or your body be influenced by your spirit. Be neither insufficiently spirited nor over spirited. An elevated spirit is weak and a low spirit is weak. Do not let the enemy see your spirit.
Small people must be completely familiar with the spirit of large people, and large people must be familiar with the spirit of small people. Whatever your size, do not be misled by the reactions of your own body. WIth your spirit open and unconstricted, look at things from a high point of view. You must cultivate your wisdom and spirit. Polish your wisdom: learn public justice, distinguish between good and evil, study the Ways of different arts one by one. When you cannot be deceived by men you will have realised the wisdom of 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.
Stance in Strategy
Adopt a stance with the head erect, neither hanging down, nor looking up, nor twisted. Your forehead and the space between your eyes should not be wrinkled. Do not roll your eyes nor allow them to blink, but slightly narrow them. With your features composed, keep the line of your nose straight with a feeling of slightly flaring your nostrils. Hold the line of the rear of the neck straight: instil vigour into your hairline, and in the same way from the shoulders down through your entire body. Lower both shoulders and, without the buttocks jutting out, put strength into your legs from the knees to the tips of your toes. Brace your abdomen so that you do not bend at the hips. Wedge your companion sword in your belt against your abdomen, so that your belt is not slack — this is called 'wedging in'.
In all forms of strategy, it is necessary to maintain the combat stance in everyday life and to make your everyday stance your combat stance. You must research this well.
The Gaze in Strategy
The gaze should be large and broad. This is the twofold gaze 'Perception and Sight'. Perception is strong and sight week.
In strategy it is important to see distant things as if they were close and to take a distanced view of close things. It is important in strategy to know the enemy's sword and not to be distracted by insignificant movements of his sword. You must study this. The gaze is the same for single combat and for large-scale strategy.
It is necessary in strategy to be able to look to both sides without moving the eyeballs. You cannot master this ability quickly. Learn what is written here; use this gaze in everyday life and do not vary it whatever happens.
Holding the Long Sword
Grip the long sword with a rather floating feeling in your thumb and forefinger, with the middle finger neither tight nor slack, and with the last two fingers tight. It is bad to have play in your hands.
When you take up a sword, you must feel intent on cutting the enemy. As you cut an enemy you must not change your grip, and your hands must not 'cower'. When you dash the enemy's sword aside, or ward it off, or force it down, you must slightly change the feeling in your thumb and forefinger. Above all, you must be intent on cutting the enemy in the way you grip the sword.
The grip for combat and for sword-testing is the same. There is no such thing as a 'man-cutting grip'.
Generally, I dislike fixedness in both long swords and hands. Fixedness means a dead hand. Pliability is a living hand. You must bear this in mind.
Footwork
With the tips of your toes somewhat floating, tread firmly with your heels. Whether you move fast or slow, with large or small steps, your feet must always move as in normal walking. I dislike the three walking methods
