This art raise in me thoughts about the human mind:
We can see the shape is in the sky, which leads us to think of somthing that is not completely earthly - something more spiritual - the human mind.
Now - we can see colorful shapes creating a somewhat rough circle, and in the center of the circle there is a strong light emitting out, a little like a small sun - a person is always a complicated thing, having many colors and sides to his personality, but if you take the time and courage to look deeper into a person, you might glimpse his innermost point, the root of his personality. This is not somthing that can be described, it can just be felt - just like we can't look at the sun directly, but need to cover it in order to get to see some of it's light.
