It is difficult for a fool's habits to change to selflessness.

A warrior should not say something fainthearted, even casually. He should set his mind to this beforehand. Even in trifling matters the depths of one's heart can be seen.

If a warrior is not unattached to life and death, he will be of no use whatsoever. The saying that “All abilities come from one mind” sounds as though it has to do with sentient matters, but it is in fact a matter of being unattached to life and death. With such non-attachment one can accomplish any feat.

When something out of the ordinary happens, it is ridiculous to say that it is a mystery or a portent of something to come... the mystery is created in (their) minds, and by waiting for disaster, it is from their very minds that it occurs.

It is said that what is called "the spirit of an age" is something to which one cannot return. That this spirit gradually dissipates is due to the world's coming to an end. For this reason, although one would like to change today's world back to the spirit of one hundred years or more ago, it cannot be done. Thus it is important to make the best out of every generation.

By being impatient, matters are damaged and great works cannot be done

Light matters should be dealt with seriously. Serious matters should be dealt with lightly.
