It does not come from the cells of your brain. Your thoughts don’t come from these cells either. The sense of beauty is the way that we experience how different energies in the true place interact. All the energies in the non-physical non-place have their own identities and styles of action. But at the same time they are all intermixed and work together perfectly all the time. Very much like you, when you are in peace. Your excitement about a mountain and a river and a tree and a bird in flight, all have their unique patterns, and they are in perfect harmony, never stirring the calm. Never changing the wellbeing, never eliminating or even reducing the freedom of choice. All of them in one person we are, and as such all of us are parts of the big one too. And when we experience how the energies intermix and inter-live, we experience a composition. Once we translated it to colors and shapes on the paper, it is gone and a new composition comes into being. When we discover the beauty in a conflict, the conflict goes away. This is how it is healing. You can be fascinated forever, and this is in fact what you do.
So every time that we paint a composition, we bring the joy of another dimension into a physical appearance. Look at a good composition and you see perfect democracy, perfect self-expression and perfect collaboration of joy, where no one loses his unique identity.
This is why working with the composition in art, instead of working with the contents, is healing. Working with the contents brings us to separation. Working with the composition and indeed with the sense of beauty brings us into the perfect unity with all.
