Re: Bokken - from the spine or not?
If your back is straight , then your bokken can go all the way down to your "behind",

The exaggeration will introduce you to the centrifugal power that starts the cut,then it ends centripetally (going inwards),
if you start from jodan position you may not get the feel of it,later on you should get these powers going from jodan position.
