O ye beloved ones of God! The manifestation of the Light of Unity is for binding together the people of the world. If this unity is not attained, the tree of life is made fruitless, the heavenly bounty is not utilized. The blessed blood (of the saints) was shed for bringing about unity and harmony. These souls gave their lives as sacrifice in order to produce the love that bindeth the hearts of all the people. Therefore, ye should all spend your efforts in uniting and reconciling (the people), so that the light of God’s love may permeate the universe.
