The Dojo Kun is recited at the beginning and end of class. It is the philosophy which all practitioners of karate should follow. The lines are recited in order of importance with the first line, "Seek Perfection of Character," being the most important. All karateka should strive to become the best they can possibly be in every way possible, to continually seek perfection no matter how unattainable. Next they must "Be Faithful," and practice diligently and frequently. They must also "Endeavor," and never give up no matter how difficult a task, exercise, or opponent may be. It takes an indomitable spirit to overcome exhaustion and pain yet still continue training or fighting. All karateka should also "Respect Others." A good student should practice hard, but still be humble and modest about their accomplishments, and they must never allow themselves to be cruel to or take advantage of others. Finally, karateka should attempt to "Refrain From Violent Behavior." They should not learn karate for the sole purpose of hurting others. Remember that in karate there is no first attack. Even when confronted by violence, such as a robbery, karate practitioners should restrain themselves, because no material possession is worth the risk of losing one's life. Physical retaliation should only happen when a person's life is being threatened.
