“Men are ignorant that the purpose of the sword is to save every man from slavery.”

The Saviors of God (1923)
Context: Every man has his own circle composed of trees, animals, men, ideas, and he is in duty bound to save this circle. He, and no one else. If he does not save it, he cannot be saved.
These are the labors each man is given and is in duty bound to complete before he dies. He may not otherwise be saved. For his own soul is scattered and enslaved in these things about him, in trees, in animals, in men, in ideas, and it is his own soul he saves by completing these labors.

Go Rin No Sho (1645), The Ground Book
Context: 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.
