Those who were able to soar upward by the power of their imagination have been living poets. What they said was not only a statement, it was music itself; it not only had a rhythm, but it had also a tone in it. It made their souls dance and it would make anyone dance who heard their poetry. Thus Hafiz of Shiraz gives a challenge to the dignified, pious men of his country when he says, "Pious friends, you would forget your dignity if you would hear the song which came from my glowing heart." And it is such souls who have touched the highest summits of life, so that they have been able to contribute some truth, giving an interpretation of human nature and the inner law of life.
