The Disconnect.

You cannot understand something by what you call it. Just because you can name something does not mean you are actually 'naming' something.
A tree is not truly a tree just because you call it a 'tree,' it is definitely something more, but that something more is what makes it a 'tree,' at least insofar as we can comprehend.

Just because you can punch or kick does not mean you understand violence, even reading a few books here and there by those who have been there, they are just words, words do not make the thing, words are a result of the thing.
Does the result breed understanding? The reflection is still just a reflection, a slight ripple that alludes to something more. That does not mean it is powerless to look at something a certain way, nor is it pointless, but certainly that which moves beyond is much more powerful as it is rooted in reality.

This is why reality is so different, because we have all these ideas floating around, they float all the time, so often that we actually believe them, we become attached to them as if they were real unto themselves.
It becomes so convincing that we even miss the opportunity to learn something from someone that has glimpsed a little further than ourselves. That is dangerous when reality comes knocking as the whole thing can, and will, be dashed to pieces - leaving nothing but a tattered husk of a thing in its' wake.

A punch may just be a punch, but just because it is called a punch does not mean there is not more to it.
Focusing solely on the punch is not the issue, it is not even the proper point of focus, and that is where we tend to get hung up.
Like taking Jyu Kumite for the real thing, or thinking just because we do some drills over and over that this means we can fight, the point has been missed on all counts. Firstly, that any of this really equates to fighting at all, secondly, that the drills, or the Kumite (form) have anything to do with violence (formlessness).
Yet at the same time what appears chaotic is not quite so chaotic to begin with; there is a method to the madness and a madness to the method, necessarily in that order.

What is the difference between saying 'chipped tooth' and the actual thing? Besides a trip to the Dentist?
The fact that you are not thinking about what it means at the time, it is ultimately very clear in that particular moment, all you may be thinking is 'Ow! Dammit!'
