Erelong will your brethren from Europe and America journey
to Persia. There they will promote to an unprecedented degree the interests of
art and industry. There they will rear the institutions of true civilization,
promote the development of husbandry and trade, and assist in the spread of
education.... Assuredly they will come; assuredly they will contribute in
making of the land of Írán the envy and the admiration of the peoples and
nations of the world.
(‘Abdu’l-Baha, quoted by Shoghi Effendi in a letter dated
February 12, 1929, ‘Baha’i Administration’)
