This is kinda an off-shoot of the other thread, but I would like this question addressed. Where did SKH get the stuff he put in his books-- especially the 6 book series he did? I know some of it is his own interpretation of ninjutsu and his attempt to systemitize it-- godai. But what about all the mental/spiritual stuff? The Observer meditation. The feelings section of the godai? If this is not from Soke, then where did it come? And why would he put it in his "ninjutsu" book if it wasn't from Soke (ie, from ninjutsu)?
