Bruce Juchnik Hanshi is well-qualified to make a statement such as this. Kosho Shorei Ryu Kempo originated in Japan. To practitioners, Kosho Ryu's Chinese roots are apparent in its basic philosophy. Because Kosho teaches them to look for similarities, they see no substantial difference between Kosho and studies from Korea, Indonesia, China, or America. All human beings move basically the same way.
All motion is related.
The same emotions are experienced by all of mankind. Fundamentally, human beings are similar, throughout continents, cultures, and time. The study of physics is only part of the understanding of Natural Law. Kosho Ryu Kempo-ka also study the natural laws of our basic individual philosophy. In so doing one can understand the physics of both our internal and external structures.
