Two simple steps to achieve peace on earth

Were man to appreciate the greatness of his station and the loftiness of his destiny he would manifest naught save goodly character, pure deeds, and a seemly and praiseworthy conduct. If the learned and wise men of goodwill were to impart guidance unto the people, the whole earth would be regarded as one country. Verily this is the undoubted truth.
