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.

The deepest love is often hidden.

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.

Even if one's head were to be suddenly cut off, he should be able to do one more action with certainty.

As everything in this world is but a sham, Death is the only sincerity.
