"Do not let yourself be guided by the feeling of lust or love."
"The gaze should be large and broad. This is the twofold gaze "Perception and Sight". Perception is strong and sight weak. 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 combat."
"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."
"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."
"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."
"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."
"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 absorb these things into your body."
"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."
"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."
"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."
"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 judgment and understanding for everything. Perceive those things which cannot be seen. Pay attention even to trifles. Do nothing which is of no use."
"You win in battles with the timing in the Void born of the timing of cunning by knowing the enemies' timing, and this using a timing which the enemy does not expect. All the five books are chiefly concerned with timing. You must train sufficiently to appreciate all this."
"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."
"There is timing in everything. Timing in strategy cannot be mastered without a great deal of practice."
"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."
"If you learn "indoor" techniques, you will think narrowly and forget the true Way. Thus you will have difficulty in actual encounters."
"There is a time and a place for use of weapons. The best use of the companion sword is in a confined space, or when you are engaged closely with an opponent. The long sword can be used effectively in all situations. The halberd is inferior to the spear on the battlefield. With the spear you can take the initiative; the halberd is defensive. In the hands of one of two men of equal ability, the spear gives a little extra strength. Spear and halberd both have their uses, but neither is very beneficial in confined spaces."
"To master the virtue of the long sword is to govern the world and oneself, thus the long sword is the basis of strategy. The principle is "strategy by means of the long sword". If he attains the virtue of the long sword, one man can beat ten men. Just as one man can beat ten, so a hundred men can beat a thousand, and a thousand men can beat ten thousand. In my strategy, one man is the same as ten thousand, so this strategy is the complete warrior's craft. The Way of the warrior does not include other Ways, such as Confucianism, Buddhism, certain traditions, artistic accomplishments and dancing. But even though these are not part of the Way, if you know the Way broadly you will see it in everything. Men must polish their particular Way."
"These things cannot be explained in detail. From one thing, know ten thousand things. When you attain the Way of strategy there will not be one thing you cannot see. You must study hard."
"There is no fast way of wielding the long sword. The long sword should be wielded broadly, and the companion sword closely. This is the first thing to realise. According to this Ichi school, you can win with a long weapon, and yet you can also win with a short weapon. In short, the Way of the Ichi school is the spirit of winning, whatever the weapon and whatever its size."
"Students of the Ichi school Way of strategy should train from the start with the sword and long sword in either hand. This is the truth: when you sacrifice your life, you must make fullest use of your weaponry. It is false not to do so, and to die with a weapon yet undrawn."
"It is said the warrior's is the twofold Way of pen and sword, and he should have a taste for both Ways. Even if a man has no natural ability he can be a warrior by sticking assiduously to both divisions of the Way. Generally speaking, the Way of the warrior is resolute acceptance of death."
"Strategy is the craft of the warrior. Commanders must enact the craft, and troopers should know this Way. There is no warrior in the world today who really understands the Way of strategy. There are various Ways. There is the Way of salvation by the law of Buddha, the Way of Confucius governing the Way of learning, the Way of healing as a doctor, as a poet teaching the Way of Waka, tea, archery, and many arts and skills. Each man practices as he feels inclined."
"When I reached thirty I looked back on my past. The previous victories were not due to my having mastered strategy. Perhaps it was natural ability, or the order of heaven, or that other schools' strategy was inferior. After that I studied morning and evening searching for the principle, and came to realise the Way of strategy when I was fifty. Since then I have lived without following any particular Way. Thus with the virtue of strategy I practise many arts and abilities — all things with no teacher. To write this book I did not use the law of Buddha or the teachings of Confucius, neither old war chronicles nor books on martial tactics. I take up my brush to explain the true spirit of this Ichi school as it is mirrored in the Way of heaven and Kwannon. The time is the night of the tenth day of the tenth month, at the hour of the tiger."
"I have climbed mountain Iwato of Higo in Kyushu to pay homage to heaven, pray to Kwannon, and kneel before Buddha. I am a warrior of Harima province, Shinmen Musashi No Kami Fujiwara No Genshin, age sixty years. From youth my heart has been inclined toward the Way of strategy. My first duel was when I was thirteen, I struck down a strategist of the Shinto school, one Arima Kihei. When I was sixteen I struck down an able strategist Tadashima Akiyama. When I was twenty-one I went up to the capital and met all manner of strategists, never once failing to win in many contests."
"I have been many years training in the Way of strategy, called Ni Ten Ichi Ryu, and now I think I will explain it in writing for the first time."
"Fifthly, the book of the Void. By Void I mean that which has no beginning and no end. Attaining this principle means not attaining the principle. The Way of strategy is the Way of nature. When you appreciate the power of nature, knowing the rhythm of any situation, you will be able to hit the enemy naturally and strike naturally. All this is the Way of the Void. I intend to show how to follow the true Way according to nature in the book of the Void."
"Fourthly the Wind book. This book is not concerned with my Ichi school but with other schools of strategy. By Wind I mean old traditions, present-day traditions, and family traditions of strategy. Thus I clearly explain the strategies of the world. This is tradition. It is difficult to know yourself if you do not know others. To all Ways there are side-tracks. If you study a Way daily, and your spirit diverges, you may think you are obeying a good way, but objectively it is not the true Way. If you are following the true Way and diverge a little, this will later become a large divergence. You must realise this. Other strategies have come to be thought of as mere sword-fencing, and it is not unreasonable that this should be so. The benefit of my strategy, although it includes sword-fencing, lies in a separate principle. I have explained what is commonly meant by strategy in other schools in the Wind book."
"Resentment and complaint are appropriate neither for oneself or others."
"In all things have no preferences."
"Be indifferent to where you live."
"Do not pursue the taste of good food."
"Do not hold on to possessions you no longer need."
"Do not act following customary beliefs"
"Do not collect weapons or practice with weapons beyond what is useful."
"Do not fear death."
"Do not seek to possess either goods or fiefs for your old age."
"Respect Buddha and the gods without counting on their help."
"You may abandon your own body but you must preserve your honour."
"Never stray from the Way."
"Third is the Fire book. This book is about fighting. The spirit of fire is fierce, whether the fire be small or big; and so it is with battles. The Way of battles is the same for man to man fights and for ten thousand a side battles. You must appreciate that spirit can become big or small. What is big is easy to perceive: what is small is difficult to perceive. In short, it is difficult for large numbers of men to change position, so their movements can be easily predicted. An individual can easily change his mind, so his movements are difficult to predict. You must appreciate this. The essence of this book is that you must train day and night in order to make quick decisions."
"Second is the Water book. With water as the basis, the spirit becomes like water. Water adopts the shape of its receptacle, it is sometimes a trickle and sometimes a wild sea. … If you master the principles of sword-fencing, when you freely beat one man, you beat any man in the world. The spirit of defeating a man is the same for ten million men. … The principle of strategy is having one thing, to know ten thousand things."
"The Way is shown in five books concerning different aspects. These are Ground, Water, Fire, Wind, and Void. The body of the Way of strategy from the viewpoint of my Ichi school is explained in the Ground book. It is difficult to realise the true Way just through sword-fencing. Know the smallest things and the biggest things, the shallowest things and the deepest things. As if it were a straight road mapped out on the ground, the first book is called the Ground book."
"Never let yourself be saddened by a separation."
"Never be jealous."
"Do not regret what you have done."
"Be detached from desire your whole life long."
"Think lightly of yourself and deeply of the world."
"Do not, under any circumstances, depend on a partial feeling."
"Do not seek pleasure for its own sake."
