By Alexander C. Kafka, Special To The Washington Post How wonderful it is that Rumi, the 13th-century Muslim versifier, has become the best-selling poet in the United States!

Rumi, like Omar Khayyam, has become the warm and fuzzy ecumenical poet of choice for weddings, coming-of-age ceremonies and funerals.
