Polish your wisdom: learn public justice, distinguish between good and evil, study the ways of different arts one by one. - Miyamoto Musashi

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.

"To become the enemy" means to think yourself into the enemy's position. In the world people tend to think of a robber trapped 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.

Among the people also, a sailor with a rudder or oars or a farmer with a spade and a hoe each in his way succeeds in accustoming himself to his action. You too can acquire strength through regular exercise. Nonetheless, it is appropriate for each person to choose a sword that corresponds to his strength.
