Reading this thread and others I have noticed that nobody hardly speaks about Kokyu and since kokyu
was something O´sensei talked about a lot I believe it is closely related to internal training/ internal power ?
Any takes on how Kokyu is manifested in the context of the internal power / internal training subject ?
Is Kokyo related to waza or is it connected to internal training, or both ?
Kokyu is only -one- aspect. In and of itself it is not enough.
