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.
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.
