“A musician once said: In art, truth and reality begin when one no longer understands what one is doing or what one knows, and when there remains an energy that is all the stronger for being constrained, controlled and compressed. It is therefore necessary to present oneself with the greatest humility: white, pure and candid with a mind as if empty, in a spiritual state analogous to that of a communicant approaching the Lord's Table. Obviously it is necessary to have all of one's experience behind one, but to preserve the freshness of one's instincts.”
