The philosophy is so different because it is coming from a martial art science approach that is new in mainstream society. Its demonstrating and illustrating how to, which in turn can be used as a tool that will help a person strengthen themselves regardless what area of their life.
If you are a person who is looking to grow and learn new things to better yourself, then Mushin will do that do that for you. Look beyond the martial arts because there is a martial artist in every one of us. It's just inside each of us waiting to come out.
