I guess we are lucky in my school. Our Hanshi is very open to other styles and welcomes thought and input from others who have studied other styles. Maybe this is because in his more than forty years of experience he himself has taken other styles and incorporates his knowledge of those into our style. One example of this is we have this gentleman who is a Shodan in another style come to our class wishing to work out with us. Our Hanshi is always careful about other people wanting to come to class just to workout, there are those who go from school to school and try and steal students away to thier own school by telling them whats wrong with the system they're taking. Well this guy was legit and was very respectful to our Hanshi. This gentleman also has a history in Jujitsu which our Hanshi isn't a big fan of just because in his past jobs he had many years ago as a bouncer and bodyguard you didn't want to find yourself locked up with someone on the ground, especially in a club where a guy is bound to have some buddies with him to help. But he tells us that this doesn't mean that he doesn't want us to learn it and know it just because he's not a fan. Don't get me wrong, he loves Jujitsu and thinks its a great art. It just didn't work for him. He'll be the first to tell you that there is no bad art, just bad instructors. This other black belt offered to teach us what he knows about Jujitsu and our Hanshi was very accepting of it. And he now is learning our style and katas to incorporate into his own. I believe learning other styles can only make you a better Martial Artist in the long run. Sure, have a base style but don't be told that it's the way and only way. Very nice article.
