To Become the Enemy
"To become the enemy" means to think yourself in the enemy's position. In the world people tend to think of a robber trabbed in a house as a fortified enemy. However, if we think of "becoming the enemy", we feel that the whole world is against us and that there is no escape. He who is shut inside is a pheasant. He who enters to arrest is a hawk. You must appreciate this.
In large-scale strategy, people are always under the impression that the enemy is strong, and so tend to become cautious. But if you have good soldiers, and if you understand the principles of strategy, and if you know how to beat the enemy, there is nothing to worry about.
In single combat also you must put yourself in the enemy's position. If you think, "Here is a a master of the Way, who knows the principles of strategy", then you will surely lose. You must consider this deeply.
To Release Four Hands
"To release four hands" is used when you and the enemy are contending with the same spirit, and the issue cannot be decided. Abandon this spirit and win through an alternative resource.
In large-scale strategy, when there is a "four hands" spirit, do not give up — it is man's existence. Immediately throw away this spirit and win with a technique the enemy does not expect.
In single combat also, when we think we have fallen into the "four hands" situation, we must defeat the enemy by changin our mind and applying a suitable technique according to his condition. You must be able to judge this.
To Move the Shade
"To move the shade" is used when you cannot see the enemy's spirit.
In large-scale strategy, when you cannot see the enemy's position, indicate that you are about to attack strongly, to discover his resources. It is easy then to defeat him with a different method once you see his resources.
In single combat, if the enemy takes up a rear or side attitude of the long sword so that you cannot see his intention, make a feint attack, and the enemy will show his long sword, thinking he sees your spirit. Benefiting from what you are shown, you can win with certainty. If you are negligen you will miss the timing. Research this well.
To Hold Down a Shadow
"Holding down a shadow" is use when you can see the enemy's attacking spirit.
In large-scale strategy, when the enemy embarks on an attack, if you make a show of strongly suppressing his technique, he will change his mind. Then, altering your spirit, defeat him by forestalling him with a Void spirit.
Or, in single combat, hold down the enemy's strong intention with a suitable timing, and defeat him by forestalling him with this timing. You must study this well.
To Pass On
Many things are said to be passed on. Sleepiness can be passed on, and yawning can be passed on. Time can be passed on also.
In large-scale strategy, when the enemy is agitated and shows an inclination to rush, do not mind in the least. Make a show of complete calmness, and the enemy will be taken by this and will become relaxed. When you see that this spirit has been passed on, you can bring about the enemy's defeat by attacking strongly with a Void spirit.
In single combat, you can win by relaxing your body and spirit and then, catching on to the moment the enemy relaxes, attack strongly and quickly, forestalling him.
What is know as "getting someone drunk" is similar to this. You can also infect the enemy with a bored, careless, or weak spirit. You must study this well.
To Cause Loss of Balance
Many things can cause a loss of balance. One cause is danger, another is hardship, and another is surprise. You must research this.
In large-scale strategy it is important to cause loss of balance. Attack without warning where the enemy is not expecting it, and while his spirit is undecided follow up your advantage and, having the lead, defeat him.
Or, in single combat, start by making a show of being slow, then suddenly attack strongly. Without allowing him space for breath to recover form the fluctuation of spirit, you must grasp the opportunity to win. Get the feel of this.
To Frighten
Fright often occurs, caused by the unexpected.
In large-scale strategy you can frighten the enemy not just by what you present to their eyes, but by shouting, making a small force seem large, or by threatening them from the flank without warning. These things all frighten. You can win by making best use of the enemy's frightened rhythm.
In single combat, also, you must use the advantage of taking the enemy unawares by frightening him with your body, long sword, or voice, to defeat him. You should research this well.
To Soak In
When you have come to grips and are striving together with the enemy, and you realise that you cannot advance, you "soak in" and become one with the enemy. You can win by applying a suitable technique while you are mutually entangled.
In battles involving large numbers as well as in fights with small numbers, you can often win decisively with the advantage of knowing how to "soak" into the enemy, whereas, were you to draw apart, you would lose the chance to win. Research this well.
To Injure the Corners
It is difficult to move strong things by pushing directly, so you should "injure the corners".
In large-scale strategy, it is beneficial to strike at the corners of the enemy's force. If the corners are overthrown, the spirit of the whole body will be overthrown. To defeat the enemy you must follow up the attack when the corners have fallen.
In single combat, it is easy to win once the enemy collapses. This happens when you injure the "corners" of his body, and thus weaken him. It is important to know how to do this, so you must research deeply.
To Throw into Confusion
This means making the enemy lose resolve.
In large-scale strategy we can use our troops to confuse the enemy on the field. Observing the enemy's spirit, we can make him think, "Here? There? Like that? Like this? Slow? Fast?". Victory is certain when the enemy is caught up in a rhythm which confuses his spirit.
In single combat, we can confuse the enemy by attacking with varied techniques when the chance arises. Feint a thrust or cut, or make the enemy think ou are going to close with him, and when he is confused you can easily win.
This is the essence of fighting, and you must research it deeply.
The Three Shouts
THe three shouts are divided thus: before, during and after. Shout according to the situation. The voice is a thing of life. We shout against fires and so on, against the wind and the waves. The voice shows energy.
In large-scale strategy, at the start of battle we shout as loudly as possible. During the fight, the voice is low-pitched, shouting out as we attack. After the contest, we shout in the wake of our victory. These are the three shouts.
In single combat, we make as if to cut and shout "Ei!" at the same time to disturb the enemy, then in the wake of our shout we cut with the long sword. We shout after we have cut down the enemy — this is to announce victory. This is called "sen go no koe" (before and after voice). We do not shout simultaneously with flourishing the long sword. We shout during the fight to get into rhythm. Research this deeply.
To Mingle
In battles, when the armies are in confrontation, attack the enemy's strong points and, when you see that they are beaten back, quickly separate and attack yet another strong point on the periphery of his force. The spirit of this is like a winding mountain path.
This is an important fighting method for one man against many. Strike down the enemies in one quarter, or drive them back, then grasp the timing and attack further strong points to right and left, as if on a winding mountain path, weighing up the enemies' disposition. When you know the enemies' level attack strongly with no trace of retreating spirit.
What is meant by "mingling" is the spirit of advancing and becoming engaged with the enemy, and not withdrawing even one step. You must understand this.
To Crush
This means to crush the enemy regarding him as being weak.
 
; In large-scale strategy, when we see that the enemy has few men, or if he has many men but his spirit is weak and disordered, we knock the hat over his eyes, crushing him utterly. If we crush lightly, he may recover. You must learn the spirit of crushing as if with a hand-grip.
In single combat, if the enemy is less skilful than ourself, if his rhythm is disorganised, or if he has fallen into evasive or retreating attitudes, we must crush him straightaway, with no concern for his presence and without allowing him space for breath. It is essential to crush him all at once. The primary thing is not to let him recover his position even a little. You must research this deeply.
The Mountain-Sea Change
The "mountain-sea" spirit means that it is bad to repeat the same thing several times when fighting the enemy. There may be no help but to do something twice, but do not try it a third time. If you once make an attack and fail, ther is little chance of success if you use the same approach again. If you attempt a technique which you have previously tried unsuccessfully and fail yet again, then you must change your attacking method.
If the enemy thinks of the mountains, attack like the sea; and if he thinks of the sea, attack like the mountains. You must research this deeply.
To Penetrate the Depths
When we are fighting with the enemy, even when it can be seen that we can win on the surface with the benefit of the Way, if his spirit is not extinguished, he may be beaten superficially yet undefeated in spirit deep inside. With this principle of "penetrating the depths" we can destroy the enemy's spirit in its depths, demoralising him by quickly changing our spirit. This often occurs.
Penetrating the depths means penetrating with the long sword, penetrating with the body, and penetrating with the spirit. This cannot be understood in a generalisation.
Once we have crushed the enemy in the depths, there is no need to remain spirited. But otherwise we must remai spirited. If the enemy remains spirited it is difficult to crush him. You must train in penetrating the depths for large-scale strategy and also single combat.
To Renew
"To renew" applies when we are fighting with the enemy, and an entangled spirit arises where there is no possible resolution. We must abandon our efforts, think of the situation in a fresh spirit then win in the new rhythm. To renew, when we are deadlocked with the enemy, means that without changing our circumstance we change our spirit and win through a different technique.
It is necessary to consider how "to renew" also applies in large-scale strategy. Research this diligently.
Rat's Head, Ox's Neck
"Rat's head and ox's neck" means that, when we are fighting with the enemy and both he and we have become occupied with small points in an entangled spirit, we must always think of the Way of strategy as being both a rat's head and an ox's neck. Whenever we have become preoccupied with small detail, we must suddenly change into a large spirit, interchanging large with small.
This is one of the essences of strategy. It is necessary that the warrior think in this spirit in everyday life. You must not depart from this spirit in large-scale strategy nor in single combat.
The Commander Knows the Troops
"The commander knows the troops" applies everywhere in fights in my Way of strategy.
Using the wisdom of strategy, think of the enemy as your own troops. When you think in this way you can move him at will and be able to chase him around. You become the general and the enemy becomes your troops. You must master this.
To Let Go the Hilt
There are various kinds of spirit involved in letting go the hilt.
There is the spirit of winning without a sword. There is also the spirit of holding the long sword but not winning. The various methods cannot be expressed in writing. You must train well.
The Body of a Rock
When you have mastered the Way of strategy you can suddenly make your body like a rock, and ten thousand things cannot touch you. This is the body of a rock.
You will not be moved. Oral tradition.
What is recorded above is what has been constantly on my mind about Ichi school sword fencing, written down as it came to me. This is the first time I have written about my technique, and the order of things is a bit confused. It is difficult to express it clearly.
This book is a spiritual guide for the man who wishes to learn the Way.
My heart has been inclined to the Way of strategy from my youth onwards. I have devoted myself to training my hand, tempering my body, and attaining the many spiritual attitudes of sword fencing. If we watch men of other schools discussing theory, and concentrating on techniques with the hands, even though they seem skilful to watch, they have not the slightest true spirit.
Of course, men who study in this way think they are training the body and spirit, but it is an obstacle to the true Way, and its bad influence remains for ever. Thus the true Way of strategy is becoming decadent and dying out.
The true Way of sword fencing is the craft of defeating the enemy in a fight, and nothing other than this. If you attain and adhere to the wisdom of my strategy, you need never doubt that you will win.
THE WIND BOOK
In strategy you must know the Ways of other schools, so I have written about various other traditions of strategys in this the Wind Book.
Without knowledge of the Ways of other schools, it is difficult to understand the essence of my Ichi school. Looking at other schools we find some that specialise in techniques of strength using extra-long swords. Some schools study the Way of the short sword, known as kodachi. Some schools teach dexterity in large numbers of sword techniques, teaching attitudes of the sword as the "surface" and the Way as the "interior".
That none of these are the true Way I show clearly in the interior of this book — all the vices and virtues and rights and wrongs. My Ichi school is different. Other schools make accomplishments their means of livelihood, growing flowers and decoratively colouring articles in order to sell them. This is definately not the Way of strategy.
Some of the world's strategists are concerned only with sword-fencing, and limit their training to flourishing the long sword and carriage of the body. But is dexterity alone sufficient to win? This is not the essence of the Way.
I have recorded the unsatisfactory point of other schools one by one in this book. You must study these matters deeply to appreciate the benefit of my Ni To Ichi school.
Other Schools Using Extra-Long Swords
Some other schools have a liking for extra-long swords. From the point of view of my strategy these must been seen as weak schools. This is because they do not appreciate the principle of cutting the enemy by any means. Their preference is for the extra-long sword and, relying on the virtue of its length, they think to defeat the enemy from a distance.
In this world it is said, "One inch gives the hand advantage", but these are the idle words of one who does not know strategy. It shows the inferior strategy of a weak spirit that men should be dependent on the length of their sword, fighting from a distance without the benefit of strategy.
I expect there is a case for the school in question liking extra-long swords as part of its doctrine, but if we compare this to real life it is unreasonable. Surely we need not necessarily be defeated if we are using a short sword, and have no long sword?
It is difficult for these people to cut the enemy when at close quarters because of the length of the long sword. The blade path is large so the long sword is an encumbrance, and they are at a disadvantage compared to theman armed with a short companion sword.
From olden times it has been said: "Great and small go together.". So do not unconditionally dislike extra-long swords. What I dislike is the inclination towards the long sword. If we consider large-scale strategy, we can think of large forces in terms of long swords, and small forces as short swords. Cannot few me give battle against many? There are many instances of few men overcoming many.
Your strategy is of no account if when called on to fight in a confined space your
heart is inclined to the long sword, or if you are in a house armed only with your companion sword. Besides, some men have not the strength of others.
In my doctrine, I dislike preconceived, narrow spirit. You must study this well.
The Strong Long Sword Spirit in Other Schools
You should not speak of strong and weak long swords. If you just wield the long sword in a strong spirit your cutting will be coarse, and if you use the sword coarsely you will have difficulty in winning.
If you are concerned with the strength of your sword, you will try to cut unreasonably strongly, and will not be able to cut at all. It is also bad to try to cut strongly when testing the sword. Whenever you cross swords with an enemy you must not think of cutting him either strongly or weakly; just think of cutting and killing him. Be intent solely upon killing the enemy. Do not try to cut strongly and, of course, do not think of cutting weakly. You should only be concerned with killing the enemy.
If you rely on strength, when you hit the enemy's sword you will inevitably hit too hard. If you do this, your own sword will be carried along as a result. Thus the saying, "The strongest hand wins", has no meaning.
In large-scale strategy, if you have a strong army and are relying on strength to win, but the enemy also has a strong army, the battle will be fierce. This is the same for both sides.
Without the correct principle the fight cannot be won.
The spirit of my school is to win through the wisdom of strategy, paying no attention to trifles. Study this well.
Use of the Shorter Long Sword in Other Schools
Using a shorter long sword is not the true Way to win.
In ancient times, tachi and katana meant long and short swords. Men of superior strength in the world can wield even a long sword lightly, so there is no case for their liking the short sword. They also make use of the length of spears and halberds. Some men use a shorter long sword with the intention of jumping in and stabbing the enemy at the unguarded moment when he flourishes his sword. This inclination is bad.
