At the point where you have succeeded in uniting body and mind, you will find that – as you continue to progress from this point – that this new state becomes the place from which waza emerge. That is: it will seem to you that from your nen – from the depths of your mind – an unlimited variety of waza emerge. And that these waza are necessarily in harmony with the laws of the natural universe, in a way that it is impossible even to talk about.
