The Báb, acclaimed by Bahá'u'lláh as the "Essence of Essences," the "Sea of Seas," the "Point round Whom the realities of the Prophets and Messengers revolve," "from Whom God hath caused to proceed the knowledge of all that was and shall be," Whose "rank excelleth that of all the Prophets," and Whose "Revelation transcendeth the comprehension and understanding of all their chosen ones," had delivered His Message and discharged His mission. He Who was, in the words of 'Abdu'l-Bahá, the "Morn of Truth" and "Harbinger of the Most Great Light," Whose advent at once signalized the termination of the "Prophetic Cycle" and the inception of the "Cycle of Fulfillment," had simultaneously through His Revelation banished the shades of night that had descended upon His country, and proclaimed the impending rise of that Incomparable Orb Whose radiance was to envelop the whole of mankind.
