In answer to the question: What is the experience of those who dive deep into life, and who touch the depth within? there is a verse in Persian by Hafiz who has said: "It is not known how far is the destination, but so much I know: that music from afar is coming to my ears." The music of the spheres, according to the point of view of the mystic, is like the lighthouse in the port that a man sees from the sea; it promises him that he is coming nearer to the destination.
