The world is in travail, and its agitation waxeth day by
day. Its face is turned towards waywardness and unbelief. Such shall be its
plight, that to disclose it now would not be meet and seemly. Its perversity
will long continue. And when the appointed hour is come, there shall suddenly
appear that which shall cause the limbs of mankind to quake. Then and only then
will the Divine Standard be unfurled, and the Nightingale of Paradise warble
its melody. (Baha’u’llah, quoted by Shoghi Effendi in a letter dated November
28, 1931; ‘The World Order of Baha’u’llah)
