“ Heart’s blood and bitter pain belong to love,And tales of problems no one can remove;Cupbearer, fill the bowl with blood, not wine -And if you lack the heart’s rich blood take mine.Love thrives on inextinguishable pain,Which tears the soul, then knits the threads again.A mote of love exceeds all bounds; it givesThe vital essence to whatever lives.But where love thrives, there pain is always found;Angels alone escape this weary round -They love without that savage agonyWhich is reserved for vexed humanity. ”
