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