"The divine purpose is that men should live in unity, concord and agreement and should love one another."

"God has created us all human, and all countries of the world are parts of the same globe. We are all His servants. He is kind and just to all. Why should we be unkind and unjust to each other? He provides for all. Why should we deprive one another? He protects and preserves all. Why should we kill our fellow creatures? If this warfare and strife be for the sake of religion, it is evident that it violates the spirit and basis of all religion. All the divine Manifestations have proclaimed the oneness of God and the unity of mankind. They have taught that men should love and mutually help each other in order that they might progress. Now if this conception of religion be true, its essential principle is the oneness of humanity. The fundamental truth of the Manifestations is peace. This underlies all religion, all justice. The divine purpose is that men should live in unity, concord and agreement and should love one another."
