This is the Day, O my Lord, which Thou didst announce unto all mankind as the Day whereon Thou wouldst reveal Thy Self, and shed Thy radiance, and shine brightly over all Thy creatures. Thou hast, moreover, entered into a covenant with them, in Thy Books, and Thy Scriptures, and Thy Scrolls, and Thy Tablets, concerning Him Who is the Day-Spring of Thy Revelation, and hast appointed the Bayán to be the Herald of this Most Great and all-glorious Manifestation, and this most resplendent and most sublime Appearance. (Baha’u’llah, "Prayers and Meditations by Bahá'u'lláh"; The Compilation of Compilations, vol. I, The Covenant)
