You can jump and twirl around and whip about your sword as quick as you want. If you aren't applying grounded techniques with your body and mind then you're just performing what I call SAMURAI THEATER.
The sword is made of different elements, heated, folded, beaten, folded, etc. etc. We begin as the unassembled elements.
Like the sword, forge yourself through the practice of true budo which utilizes more than just cute outfits and elaborate names of waza. Think about your practice carefully.
