Study the science of art. Study the art of science. Develop your senses- especially learn how to see. Realize that everything connects to everything else.

Art is the queen of all sciences communicating knowledge to all the generations of the world.

Shadow partakes of the nature of universal matter. All such matters are more powerful in their beginning and grow weaker towards the end, I say at the beginning, whatever their form or condition may be and whether visible or invisible. And it is not from small beginnings that they grow to a great size in time; as it might be a great oak which has a feeble beginning from a small acorn. Yet I may say that the oak is most powerful at its beginning, that is where it springs from the earth, which is where it is largest.
