Knowledge, purity, devotion, discipline, independence, have nothing to do with outer appearance and dress. Once in the course of My travels I heard an eminent personage make the following excellent remark, the wit and charm of which remain in memory: “Not every cleric’s turban is a proof of continence and knowledge; not every layman’s hat a sign of ignorance and immorality. How many a hat has proudly raised the banner of knowledge, how many a turban pulled down the law of God!”
