"When I used to go to other schools I would never challenge the Sensei of the dojo. An individual in charge of a dojo is burdened with many things, so it is very hard for him to display his true ability. I would pay him the proper respects and learn from him. If I judged myself superior, I would again pay him my respects and return home." (quote)
