Also by training you will be able to freely control your own body, conquer men with your body, and with sufficient training you will be able to beat ten men with your spirit. When you have reached this point, will it not mean that you are invincible?

Perceive that which cannot be seen with the eye.

The way is in training.

You should not have a favourite weapon. To become over-familiar with one weapon is as much a fault as not knowing it sufficiently well.

Determine that today you will overcome your self of the day before, tomorrow you will win over those of lesser skill, and later you will win over those of greater skill.

Do not sleep under a roof. Carry no money or food. Go alone to places frightening to the common brand of men. Become a criminal of purpose. Be put in jail, and extricate yourself by your own wisdom.

You can only fight the way you practice
