If the beloved of God in all America strive for unity and harmony, attain perfect love and accord, and act according to the divine teachings and the precepts of the Blessed Perfection, this will prove a magnet attracting Abdu’l-Baha, so that, perchance, he may journey to America.

But, until the light of oneness, unity and love shine forth from the lamp of America, and the beloved act in accordance with the divine teachings and precepts of the Blessed Perfection, and all the believers in America become united and harmonious, my coming to America will be hindered -- nay, impossible. 
(‘Abdu’l-Baha, from a Tablet, Star of the West, vol. 1, no. 16, December 31, 1910)
