There doesn't exist an offensive attitude in Karate. Karate is an aid to justice. First know yourself and then the others. The spirit is more important than the technique.
Accidents are the result of neglect.
Karate training is not only in the dojo. Karate is a lifelong training. Confront your problems with a Karate spirit. Do not foster the idea of winning neither that of being defeated. Transform yourself according to your opponent.
