Sufis have in many cases realized and shown the greatest perfection in humanity. And among the lives of the Sufi saints may be found some of the most divine models of human perfection in all capacities, from a king to a laborer. The idea that Sufism sprang from Islam or from any other religion, is not necessarily true; yet it may rightly be called the spirit of Islam, as well as the pure essence of all religions and philosophies.
