I meditate constantly my friend, I have been since I was 13. took me 2 years to get it just right.... the Point of meditateing is to complete clear your mind of all outside worries and concern so you can focus directly on what you are doing, Focusing on the Here and now. Its gotten to the Point where I no longer sit and meditate, I actually do it while sub conciously moveing through my weapons Katta wheather it be fast or slow--------- So yes it does help ... it helped a thousand years ago when the Samurai did it, nothing about Kattas and meditation have changed drastically since then
