"Things are often known by their opposites. Were it not for darkness, light could not be sensed. Were is not for death, life could not be known. If ignorance did not exist, in order that the other should have reality... Unless night was a reality there could be no day... Things are known by their opposites." Promulgation of Universal Peace Page 79 (64:5)
