 Here is a bonus video from our exploration of Goju Rukerate with guest John Paul Williams. Find a link for the full episode on the history of Goju Rukerate in the video description. So Kasai no Genri, if you were to take a lot of your bunkai and make it continuous and keep on going as in for oil, like application, bunkai is actually disassemble or to break down, oil is application. Now if you take bunkai and you make it continuous oil, you would end up with this really long series until one opponent or two, your opponent is finished. But let's be honest, you can only learn so many items in a series before you need to restart and do a new series. And Kasai no Genri comes into play here where in order to make a kata, you want to break the kata in the portions. And this includes Kempo kata also, Kempo forms also. You'll see the first part of the kata looks like this, and then suddenly you move to a new opponent, you're doing a different set of techniques. And you move over here, you're doing a different set of techniques, you move over here, you're doing a different set of techniques. Then you move back around, come this way to the front again, and you finish off with another set of techniques, if not a set of techniques that resembles one or those other four that you started off with, that you did previously. And it ends up back into the front, into the front again. So Kasai no Genri is applying those techniques in an orderly manner that's easier for the student to remember. And this helps in building and making kata. So a lot of old teachers from Miyagi, even Yamaguchi Goshi in Japan has made four new kata for Gojiru. Kasai no Genri was a big part of how do you make these new kata. Tokuchi made, I think, four kata for his gojiru association. He was a brilliant user of that theory, Kasai no Genri, using the bunkai, following the oil, not giving it so much that a student can't remember it. And then let's move to the next portion of bunkai, let's move to the next series of techniques. Bunkai is to break down, to decompose or deconstruct. Oil is to apply, and together they built Kasai no Genri, making a new kata. Celebrate the art of Gojiru karate with this commemorative forefather t-shirt, available only here at Art of Wondojo.
