What I can't think, doesn't exist. The Jewish People, the descendants of Shem proclaim to the world that the mind of man does not contain nor restrain G-d. G-d does not sit in the tent of Man. The Jewish definition of beauty is that which reveals essence. It is that which hints to a reality beyond the hollow circle of the mind of Man.
Nothing can be truly beautiful unless it expresses essence.
The face is the only part of the human being where you can see the inside of a person, where you can see the intellect dominating the physical. The true artist takes the awe of existence and turns into notes, into paint, into words. Art is not a world where Man may rule as a tyrant. Art is but the most moving reflection of the world beyond. Who says that red is nicer than blue.
