In the clustered jewels of the races may the blacks be as sapphires and rubies and the whites as diamonds and pearls. The composite beauty of humanity will be witnessed in their unity and blending. How glorious the spectacle of real unity among mankind! How conducive to peace, confidence and happiness if races and nations were united in fellowship and accord! ‘Abdu’l-Bahá, The Promulgation of Universal Peace.
