We must look at ourselves with the strictest eyes.

Some people think a martial artist has to be tough against everybody - that's not true at all. A martial artist has to be strong against bad people. But we must also be able to know and understand the feelings, moods and mentalities of good and bad individuals before we can comprehend when to be strong and when to be gentle.

Eliminating one weakness is better than adding one strength.

In order to achieve victory you must place yourself in your opponent's skin. If you don't understand yourself, you will lose one hundred percent of the time. If you understand yourself, you will win fifty percent of the time. If you understand yourself and your opponent, you will win one hundred percent of the time.

Originally this was the most important thing about martial arts - to reach a higher level, to become a strong human being. Strong doesn't mean big arms. It means who can be a more strict human being with himself. That is the ideal of martial arts.
