True karate is this: that in daily life one's mind and body be trained and developed in a spirit of humility, and that in critical times, one be devoted utterly to the cause of justice.

Students of any art, including Karate-do must never forget the cultivation of the mind and the body.

In karate, hitting, thrusting, and kicking are not the only methods, throwing techniques and pressure against joints are included … all these techniques should be studied referring to basic kata

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.

First know yourself, then know others.

Karate is a defensive art from beginning to end.

To practice kata is not to memorize an order. Find the katas that work for you, understand them, digest them & stick with them for life.
