There was a time when decorative art was highly developed, for instance in China where it reached its zenith. When the Chinese artist wished to decorate an object with a picture of the sky, he drew it with one line; and one can feel it. Where does it come from? From a mental effort? It comes from inspiration. It is one thing to think about an idea and another thing to feel the idea, and once the artist begins to feel the idea he is able to express it. Even if it is not finished, it is finished in the feeling of the artist, and that completes the lines. Those who want to will see the truth of it; they will be able to read it; they will know the object of the picture.
