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.

If you fail to take advantage of your enemies' collapse, they may recover.

One must make the warrior walk his everyday walk.

To cut and slash are two different things. Cutting, whatever form of cutting it is, is decisive, with a resolute spirit. Slashing is nothing more than touching the enemy.

You win battles by knowing the enemy's timing, and using a timing which the enemy does not expect.

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