In time of grave public crisis, one must have the courage to face a million and one opponents.

When there are no avenues of escape or one is caught even before any attempt to escape can be made, then for the first time the use of self-defense techniques should be considered. Even at times like these, do not show any intention of attacking, but first let the attacker become careless. At that time attack him concentrating one's whole strength in one blow to a vital point and in the moment of surprise, escape and seek shelter and help.

One of the most striking features of karate is that it may be engaged in by anybody, young or old, strong or weak, male or female.

Apply the way of karate to all things. Therein lies its beauty.

Success, cannot be attained alone. Any person's time and power is limited. A wise leader enlists others in working toward organizational goals.

Karate-do begins with courtesy and ends with rei.

Hoping to see karate included in the universal physical education taught in our public schools, I set about revising the kata so as to make them as simple as possible. Times change, the world changes, and obviously the martial arts must change too. The karate that high school students practice today is not the same karate that was practiced even as recently as ten years ago [this book was written in 1956], and it is a long way indeed from the karate I learned when I was a child in Okinawa.
