There is a great saying from the movie Sanjuro, "The best swords are the ones that are kept in their scabbards." At the heart of all martial arts training comes the understanding that our minds are our greatest weapons and simultaneously our worst enemies. In the Japanese traditional arts, the highest level one can attain is the ability to show restraint. A master is supposed to be someone who has kokkifukurei or the ability to demonstrate their skills in decorum and etiquette but more importantly their ability to exercise self restraint at all times. Restraint can only come after years and years of training. Restraint is the ability to do the right thing at the right time which one might call seido in Japanese or precision in English. Learn to control yourself and your emotions so that other people cannot control you.
