No movement in the world directs its attention upon both
these aspects of human life and has full measures for their improvement save
the teachings of Bahá'u'lláh. And this is its distinctive feature. If we desire
therefore the good of the world we should strive to spread those teachings and
also practice them in our own life. Through them will the human heart be
changed and also our social environment provides the atmosphere in which we can
grow spiritually and reflect in full the light of God shining through the
revelation of Bahá'u'lláh.
