Miyamoto Musashi said this quote

The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy's cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.

~ Miyamoto Musashi

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.

~ Miyamoto Musashi

In my school, no consideration is given to anything unreasonable; the heart of the matter is to use the power of the knowledge of martial arts to gain victory any way you can.

~ Miyamoto Musashi

From one thing, know ten thousand things.
