It is important that karate can be practiced by the young and old, men and women alike. That is, since there is no need for a special training place, equipment, or an opponent, a flexibility in training is provided such that the physically and spiritually weak individual can develop his body and mind so gradually and naturally that he himself may not even realize his own great progress.
Gichin FunakoshiOne whose spirit and mental strength have been strengthened by sparring with a never-say-die attitude should find no challenge too great to handle. One who has undergone long years of physical pain and mental agony to learn one punch, one kick, should be able to face any task, no matter how difficult, and carry it through to the end. A person like this can truly be said to have learned karate.
