Rumi
Rumi seems to have been permanently engaged in a search of divine inspiration and love. He saw and found his 'Muse' in various human and natural aspects of existence. After the Divan he completed his great masterpiece or magnum opus, the Mathnavi-i Ma'navi  ('The Mathnavi/Treatise Devoted to the Intrinsic Meaning of All Things'), which was dictated in its entirety to his student Hissam-ud-din Chelebi over the course of many years.
