Praise be to God! For centuries and cycles the banner of
civilization has been raised, the human world has day by day advanced and
developed, the material world has flourished and outward perfections increased
until now the world of human existence has attained great capacity for the
spiritual teachings and the divine summons.
-‘Abdu’l-Baha (From a Tablet; Star
of the West, vol. 6, no. 9, August 20, 1915)
