Say: O ye that have eyes to see! The past is the mirror of the future. Gaze ye therein and be apprised thereof; perchance ye may be aided thereby to recognize the Friend and may be not the cause of His displeasure. In this day the choicest fruit of the tree of knowledge is that which serveth the welfare of humanity and safeguardeth its interests. Bahá’u’lláh, The Tabernacle of Unity.
