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

April 20

God hath, likewise, as a bounty from His presence, abolished the concept of "uncleanness", whereby divers things and peoples have been held to be impure. He, of a certainty, is the Ever-Forgiving, the Most Generous. Verily, all created things were immersed in the sea of purification when, on that first day of Ridvan, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes. This, verily, is a token of My loving providence, which hath encompassed all the worlds. Consort ye then with the followers of all religions, and proclaim ye the Cause of your Lord, the Most Compassionate; this is the very crown of deeds, if ye be of them who understand. 
(Baha'u'llah, The Kitab-i-Aqdas)
