The former musician, Hazrat Inayat Khan gave up the practise of music "to tune souls instead of instruments, to harmonize people instead of notes ... Music, the word we use in our everyday language, is nothing less than the picture of our Beloved ... It is because music is the picture of our Beloved that we love music."
Angels are forms, images and expressions through which the essences and energy forces of God can be transmitted; and, since there are an infinite number of these forms, the greatest service anyone can pay the angelic host is never consciously to limit the ways angels might appear to us.
