That is an interesting question, and I will tell you how I understand it.

Art is an expression of human consciousness, the definition can be found here.
Art work is information about the artists consciousness. But what is consciousness? Consciousness is an evolving process of self organization. I think you will find that every moment of consciousness, is a moment of self organization. So art work is information about the artists evolving process of self organization. If you are an artist, I think you will relate to this.

The universe is an evolving process of self organization, so all of it's component parts are also an evolving process of self organization. As a galaxy falls in on itself, it must self organize, and hence so too must all of its component parts. The Milky Way, the solar system, Earth, life on earth, humanity are all a process of self organization. This being the case, what else can art possibly express but self organization?

That art expresses self organization is nothing special, all human activity is an expression of self organization.

Self organization is the fundamental process everything is involved in. Is it a God process? It is the process responsible for all creation. It would fit the idea that

I've found that every attempt to explain "everything/meaning/where to/where from/why/Tec" is nothing more then a lie with different icing and sprinkles on it because language will never be complex enough to be able to unfold the Terrain of understanding within ones mind by means of spoken/written language and regardless of how honest the intentions of the one conveying the words might be they are always going to limit life so much so that the description becomes more of a stumbling block to the recipient despite the intentions of it serving as aid to the Journey.

We have the image of God within us and were born with a responsibility in the world. That is why our existence must be based on this dignity. In the same way that God created the world, we are also able to create some things (of course, keeping in mind the proper proportions). We are the created creators.
