If you want to learn the craft of war, ponder over this book. The teacher is as a needle, the disciple is as thread. You must practice constantly.

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.

The spirit of defeating a man is the same for ten million men. The strategist makes small things into big things, like building a great Buddha from a one foot model.

With your spirit open and unconstricted, look at things from a high point of view.

Aspire to be like Mt. Fuji, with such a broad and solid foundation that the strongest earthquake cannot move you, and so tall that the greatest enterprises of common men seem insignificant from your lofty perspective. With your mind as high as Mt Fuji you can see all things clearly. And you can see all the forces that shape events; not just the things happening near to you.

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

Never depart from the way of martial arts.
