Art As Prayer...

Art as a form of active prayer. Yes. 

My take would be the art-form does not matter. It could be painting, sculpture, dance, music, theater, writing, pottery, weaving, whatever...

And the content of the art doesn't matter. Trivial, profound, exuberant, melancholic, silly, somber, enlightening, darkening, whatever...

The act itself is the act itself. It's already life-enhancing. "The expression of creative skill and imagination..."

And the prayer can be to an empty void, or a big daddy, or nature, or family of gods, or some great cloud of unknowing, whatever...
