When I asked the old man if he believed in the healing power of music, he laughed at first, and then suddenly grew serious. "I forget everything when I play. All my heart goes into the music. If I don't concentrate, the music changes, so it's best to forget all distractions and just play."
There comes a time when the world gets quiet and the only thing left is your own heart. So you'd better learn the sound of it. Otherwise you'll never understand what it's saying.
