Music, according to Sufi teaching, is really a small expression of the overwhelming and perfect harmony of the whole universe-and that is the secret of its amazing power to move us. The Indian Sufi master Hazrat Inayat Khan (1882-1927), the first teacher to bring the Islamic mystical tradition to the West, was an accomplished musician himself. His lucid exposition of music's divine nature has become a modern classic, beloved not only by those interested in Sufism but by musicians of all kinds.
