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."
Speaking of spirituality, a Sufi master once said, "A river passes through many countries, and each claims it for its own. But there is only one river."
