Here is a wonderful documentary on Karate done by NHK World.  NHK is the public broadcasting TV station in Japan.  They have many wonderful English language programs on Japan that are quite interesting. This documentary is an excellent overview of the way of Karate.  One can see not only the beauty, but the power of Karate.  At first glance, Karate might seem like a sport, but you can see by the practitioners in the documentary that it is a way of life.  All martial arts come from the same source and, while taking divergent paths, all eventually meet at the same top of the mountain.  From this documentary, one can see Aikido in Karate and Karate in Aikido.  Please don't judge.  Judging is not learning.  Please only observe and learn.
