* The line is a literal translation of the persian analogy 'Áftab Ámad Dalil-i Áftáb' meaning the appearing of the Sun is proof of the Sun and thus metaphorically implying that love indeed needs no explanation. The existence of love, is proof of Love. heh! it's a sort of cyclical reasoning! A-scientific but then as i mentioned before, it has a feel factor attached to it! Hence, according to me, it's completely futile and a waste of time to define love objectively, as humorous it is, to read physicists debate on the existence of the sun!
