A warrior is worthless unless he rises above others and stands strong in the midst of a storm.

To desire with one’s very soul every second of every day to accomplish one’s aim.

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.

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

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

There is surely nothing other than the single purpose of the present moment. A man's whole life is a succession of moment after moment. There will be nothing else to do, and nothing else to pursue. Live being true to the single purpose of the moment.

There is not a man who does not get senile by the time he reaches sixty. And when one thinks that he will not be senile, he is already so.
