That the Cause associated with the name of Bahá'u'lláh feeds itself upon those hidden springs of celestial strength which no force of human personality, whatever its glamour, can replace; that its reliance is solely upon that mystic Source with which no worldly advantage, be it wealth, fame, or learning can compare; that it propagates itself by ways mysterious and utterly at variance with the standards accepted by the generality of mankind, will, if not already apparent, become increasingly manifest as it forges ahead towards fresh conquests in its struggle for the spiritual regeneration of mankind. (Shoghi Effendi, The World Order of Baha'u'llah)
