Say: His [Baha’u’llah’s] beauty is in truth My beauty, and His Self is Mine own Self, and all that We revealed in the Bayán is for the sake of His wondrous and resistless Cause. Fear ye God, and dispute not with the One Whose advent We heralded and Whose Revelation We announced unto you. I established a covenant with you concerning His mission ere I covenanted with you regarding Mine own, and unto this all things bear witness, even if ye were to deny it. By the righteousness of God! Through but a single one of His melodies the realities of all things were reborn, and through another the hearts of His favoured ones were filled with rapture. Take heed lest anything debar you from Him Whose presence is the same as Mine own. He sacrificed Himself in My path even as I sacrificed Myself in His path for the love of His glorious and incomparable beauty.
- Bahá’u’lláh (From a Tablet; Baha'u'llah speaks in the voice of the Báb, ‘Days of Remembrance’)
