April 9

The world of being shineth in this Day with the resplendency of this Divine Revelation. All created things extol its saving grace and sing its praises. The universe is wrapt in an ecstasy of joy and gladness. The Scriptures of past Dispensations celebrate the great jubilee that must needs greet this most great Day of God. Well is it with him that hath lived to see this Day and hath recognized its station. 
(Baha’u’llah, quoted by Shoghi Effendi in, The Dispensation of Baha'u'llah)
