Anything's possible, but what's your point? If that's true (I'm not giving an opinion one way or the other), than what would it change in a discussion of the training methodology that he he himself laid down?
Excellent question Chris, the point to simply be aware that we humans seem to have a genetic predisposition to overly complicate things. I believe the founder's basic message is "Train hard, train joyfully and the world is a little better place." Breathing and intent and spirals and stress and the Doshu said and he said and she said and all the rest ... ok - but mostly "Train hard, train joyfully and the world is a little better place."
