A Sufi tries to keep harmony in his surroundings, the harmony which demands many sacrifices. It makes one endure what one is not willing to endure, it makes one overlook what one is not inclined to overlook, it makes one tolerate what one is not accustomed to tolerate, and it makes one forgive what one would never have forgotten if it had not been for the sake of harmony. But at whatever cost harmony is attained it is a good bargain, for harmony is the secret of happiness, and in the absence of this a person living in palaces and rolling in gold can be most unhappy.
