Though the changeableness of the artist in a way shows the liquidity of his mind, which is natural to him, still his control over that changeableness brings his efforts in his art to a successful issue. Concentration therefore helps the artist most in his work. Keen insight into beauty does not only help in art, but it leads the artist to spiritual perfection. There is a very thin veil between the artist and God, and it is his insight into beauty, with constant practice, which can sometimes lift the veil, so that all the beauty of nature will become to the artist one single vision of the sublime immanence of God.
