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

May 20

O ye members of Assemblies in that land and in other countries! Take ye counsel together, and let your concern be only for that which profiteth mankind, and bettereth the condition thereof, if ye be of them that scan heedfully. Regard the world as the human body which, though at its creation whole and perfect, hath been afflicted, through various causes, with grave disorders and maladies. Not for one day did it gain ease, nay, its sickness waxed more severe, as it fell under the treatment of ignorant physicians, who gave full rein to their personal desires, and have erred grievously. And if at one time, through the care of an able physician, a member of that body was healed, the rest remained afflicted as before. Thus informeth you the All-Knowing, the All-Wise. 
(Baha’u’llah, from a Tablet addressed to Queen Victoria, quoted by Baha’u’llah in the ‘Epistle to the Son of the Wolf’)
