Karate is not one style or system. Karate is all of us. Whether we practice Goju-Ryu, Shorin-Ryu, Kenpo, or Shotokan, we are all carrying on the art of Karate. From the youngest child to the oldest Sensei, each and every one of us is a thread in the great fabric of the art.
Karate does not exist in books or photographs. It only lives when we practice it. It is something to "do," not just think, talk, or read about.
Now log off, and go hit a heavy bag, practice a form, or something. :)
