Whoso ariseth among you to teach the Cause of his Lord, let him, before all else, teach his own self, that his speech may attract the hearts of them that hear him. Unless he teacheth his own self, the words of his mouth will not influence the heart of the seeker. Take heed, O people, lest ye be of them that give good counsel to others but forget to follow it themselves . . . (Baha’u’llah, ‘Gleanings from the Writings of Bahá'u'lláh’; compilation ‘Psychology and Knowledge of Self, prepared by the Research Department of the Universal House of Justice)
