When I teach aikido I try to introduce at least one concept or idea that most of the people in the class haven't heard before. Sometimes it will an idea that I did not learn in aikido but has tremendous bearing on what I am trying to illustrate. After they get the idea and understand how/where/why it applies to what we're doing, I'll tell them where it comes from. This is one way that I can show the importance of cross training, or the overlap that there is so often across various martial arts. What I am really trying to do is to get them to expand their thinking. To think outside the box. To not just be robots. Although in the begining robotics may have some importance. Thoughts?
