"The more words leave your mouth, the more noise you make and the more chances is there of making mistakes. The same is true in fighting art: the more you throw punches and kicks, the more you create noise- and make mistakes. Traditional Karatedo is a reticent approach to a complex nature of violent, "loud" assaults and works perfectly only in self-defense,"quiet", situation; it's not meant to expose and be vulnerable but to make use of the attackers's vulnerability. Hence, a serious martial artist is quiet and doesn't start any noise."
