One must make the warrior walk his everyday walk.

In the void is virtue, and no evil. Wisdom has existence, principle has existence, the Way has existence, spirit is nothingness.

You can only fight the way you practice

It is imperative to master the principles of the art of war and learn to be unmoved in mind even in the heat of the battle.

From inside fortifications, the gun has no equal among weapons. It is the supreme weapon on the field before the ranks clash, but once swords are crossed the gun becomes useless.

Even if a man has no natural ability, he can be a warrior.

Consider yourself lightly; consider the world deeply.
