To find and develop Karate as a True Art, and this would include Shotokan, Goju, Uechi, or various other types of the art, one should always look to the techniques. The bunkai are the kata made real, they are concepts made to work. They are the heart of the monster that is The True Art.
The first step, in making your art work, is to stand firmly. The forms teach a variety of stances, and how to get into them from a variety of directions and previous postures. So one should practice the patterns until this concept of transitioning from stance to stance can be done without thought.
The second step, if you are going to make the karate forms real, is to make sure your limbs are in functional positions. There are many arm positions in the martial arts techniques where your limbs cannot support weight enough to make the technique work. You must examine your form and change arm positions until they become functional in real world situations.
The third step is to have proper body alignment between the feet and the hands. The body is a chain of muscles and bones from ground to strike, and you must make sure that every piece of the body is properly aligned. The old wisdom, a chain is as strong as its weakest link, comes to mind.
The fourth step if you are going to make karate moves become significant, is to focus on your breathing. Breathing should be relaxed, but intent upon keeping the abdomen taut, especially upon hitting, or getting hit. Breathing simply for the sake of breathing, as is done in Goju Ryu Karate, must be examined for real function, and possibly altered if you are going to have real martial arts self defense.
The fifth and final step, and ultimately the most necessary, is that you must have Coordinated Body Motion (CBM) when you use your body. You must harmonize all motion, taking into account the length and mass of every muscle and limb, and the entire torso. You must understand how this all relates to timing, and you must make your body motions utilize this harmonious timing.
One of the more fascinating facts is that martial arts fighting has very little to do with finding The True Art. As a matter of fact, fighting tends to disrupt the concentration that is necessary to put the pieces together that will resurrect your martial art. This piece of knowledge is something that the old masters knew, and not just because they were old.
At any rate, any art can be great, but it requires a great teacher, and a great student. The purpose of this article has been to encourage students to be their own great teachers. Ultimately, that is who is responsible for your progress, and if you understand that then you can use Karate techniques to find the True Art.
