Do not let your opponent see your spirit

In all forms of strategy, it is necessary to maintain the combat stance in everyday life and to make your everyday stance your combat stance.

As far as Im concerned, I regret nothing.

There is no one way to salvation, whatever the manner in which a man may proceed. All forms and variations are governed by the eternal intelligence of the Universe that enables a man to approach perfection. It may be in the arts of music and painting or it may be in commerce, law, or medicine. It may be in the study of war or the study of peace. Each is as important as any other. Spiritual enlightenment through religious meditation such as Zen or in any other way is as viable and functional as any "Way."... A person should study as they see fit.

To win any battle, you must fight as if you are already dead

You may abandon your own body but you must preserve your honour.

Approach the enemy with the attitude of defeating him without delay.
