Bill the only issue I have with mindfullness is that you can't "be here now" if you don't know what to do 'here and now"... I believe martially, you must simply train, train, train...and the mindfulness follows...not leads.
I might not agree, but OTOH, there's a possibility we're saying the same thing- Train, train, train. But when it's time to apply it, focus on observing and let your backbrain call the shots. Your cognition can't possibly keep up.
