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

October 15

… behold…how He hath sent down the Manifestation of His Cause with verses which naught in the heavens or on the earth can withstand!  Such hath been the manner of their revelation that they have neither peer nor likeness in the world of being, as ye yourselves beheld and heard when once the Daystar of the world shone forth above the horizon of ‘Iráq with manifest dominion.  All things attain their consummation in the divine verses, and these indeed are the verses of God, the Sovereign Lord, the Help in Peril, the All-Glorious, the Almighty.  Beyond this, He hath been made manifest as the Bearer of a Cause whose sovereign might is acknowledged by all created things, and this none can deny save the sinners and the ungodly. 
(Baha'u'llah, ‘Suriy-i-Haykal, ‘The Summons of the Lord of Hosts’)
