It is self-evident that humanity is at variance. Human tastes differ; thoughts, native lands, races and tongues are many. The need of a collective center by which these differences may be counterbalanced and the people of the world be unified is obvious. Consider how nothing but a spiritual power can bring about this unification, for material conditions and mental aspects are so widely different that agreement and unity are not possible through outer means. It is possible, however, for all to become unified through one spirit, just as all may receive light from one sun. Therefore, assisted by the collective and divine center which is the law of God and the reality of His Manifestation, we can overcome these conditions until they pass away entirely and the races advance. Consider the time of Christ. Peoples, races and governments were many; religions, sects and denominations were various; but when Christ appeared, the Messianic reality proved to be the collective center which unified them beneath the same tabernacle of agreement. Reflect upon this. Could Jesus Christ have united these divergent factors or brought about such results through political power? Was this unity and agreement possible through material forces? It is evident that it was not; nay, rather, these various peoples were brought together through a divine power, through the breaths of the Holy Spirit. They were blended and quickened by the infusion of a new life. The spirituality of Christ overcame their difficulties so that their disagreements passed away completely. In this way these divergent peoples were unified and became welded in a bond of love which alone can unite hearts. Therefore, it is shown that the divine Manifestations, the holy Mouthpieces of God, are the Collective Centers of God. These heavenly Messengers are the real Shepherds of humanity, for whenever They appear in the world They unite the scattered sheep. The Collective Center has always appeared in the Orient. Abraham, Moses, Jesus Christ, Muḥammad were Collective Centers of Their day and time, and all arose in the East. Today Bahá’u’lláh is the Collective Center of unity for all mankind, and the splendor of His light has likewise dawned from the East. He founded the oneness of humanity in Persia. He established harmony and agreement among the various peoples of religious beliefs, denominations, sects and cults by freeing them from the fetters of past imitations and superstitions, leading them to the very foundation of the divine religions. From this foundation shines forth the radiance of spirituality, which is unity, the love of God, the knowledge of God, praiseworthy morals and the virtues of the human world. Bahá’u’lláh renewed these principles, just as the coming of spring refreshes the earth and confers new life upon all phenomenal beings. For the freshness of the former springtimes had waned, the vivification had ceased, the life-giving
