There is a story of a Persian king and a dervish. Now a dervish is a self-educated man, but one who knows and understands things. He is a free-thinker; he does not abide by the law of society; he touches the depth of the truth, and ignores all the superficial and artificial rules and laws of society and religion; he leads his life freely in thought and action; he is so happy in his philosophy that if he is clothed in rags and tatters it matters nothing to him.
