Ahh...the infamous split. You know, it's really odd. Hayes is claiming that there are two things now. On his site he is more or less coming right out and saying that he has the blessing of Hatsumi Sensei for what he is doing. And I honestly do not know what the hell is going on...on a certain level. Apparently Hatsumi Sensei has not given him the boot, so to speak. Has not stripped him of any rank, and from what I hear, Hayes still travels to Japan with Hatsumi Sensei.
There are a few split factions now, and for whatever the reasons, it's sad, but in the sadness and in some cases, bitterness...maybe there is hope that the Tradition, in some legitimate and combat-viable form will carry on regardless...I hope so.
I think if I were the Grandfather, or the Father, I would look at some of these things as my children or grandchildren marrying [injecting] knuckleheads [things not in the art] and therefore making me unhappy about the bloodline [allowing tradition to the letter lost].
When the world was a much smaller place, this was a concern of some powerful people. "Oh, I say, don't marry into the Barton Family, they're morons..."
(No offense to anyone named "Barton," I just dreamed up a name).
I have to say something and I'm sure it might make some people happy and might piss some people off...I think you will agree...
If someone has studied with Hatsumi Sensei for years, some of it has to rub off. And as long as the underlying principle is not lost, it is still going to be far better than the literally hundreds of systems and sub-systems in the Martial Arts World.
