If nature has no freedom, there is nothing to add or take away, but only to realize and recognize. If you add or take anything away, you interrupt nature. So, there is nothing to learn. You must be with nature to understand it. Nature is “as such;” the way that it is; the way things are. So the concept is: there is nothing to learn, because it is already there.
So how are we going to learn if there is nothing to learn? We learn through recognizing and realizing what is what. You cannot think. You cannot imitate. You cannot train to accumulate. If you perform a movement over and over without the right mindset, what you train will turn into a subconscious reflex (second nature) and become a habit. So you must train total awareness, total consciousness of nature.
How to be mindful to turn yourself into a receiver? Using your six senses upon contact (with an opponent), there is a period of recognizing, but the change of nature happens so fast, we cannot maintain our awareness in the moment and we fall back into thinking or responding (which is in the past). We are with nature briefly, but then it has moved on but we have not moved with it. So the training is to maintain the process of recognizing.
