God has desired for mankind the effulgence of love, but through blindness and misapprehension man has enveloped himself in veils of discord, strife and hatred. The supreme need of humanity is cooperation and reciprocity. The stronger the ties of fellowship and solidarity amongst men, the greater will be the power of constructiveness and accomplishment in all the planes of human activity.
