“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

April 19

Rejoice, with exceeding gladness, O people of Bahá! as ye call to remembrance the Day of supreme felicity, the Day whereon the Tongue of the Ancient of Days hath spoken, as He departed from His House proceeding to the Spot from which He shed upon the whole of creation the splendors of His Name, the All-Merciful... Were We to reveal the hidden secrets of that Day, all that dwell on earth and in the heavens would swoon away and die, except such as will be preserved by God, the Almighty, the All-Knowing, the All-Wise. Such is the inebriating effect of the words of God upon the Revealer of His undoubted proofs that His pen can move no longer. 
(Baha’u’llah, quoted by Shoghi Effendi in ‘God Passes By’)
