It was in such dramatic circumstances, recalling the experience of Moses when face to face with the Burning Bush in the wilderness of Sinai, the successive visions of Zoroaster, the opening of the heavens and the descent of the Dove upon Christ in the Jordan, the cry of Gabriel heard by Muḥammad in the Cave of Hira, and the dream of the Báb, in which the blood of the Imám Ḥusayn touched and sanctified His lips, that Bahá’u’lláh, He “around Whom the Point of the Bayán hath revolved,” and the Vehicle of the greatest Revelation the world has yet seen, received the first intimation of His sublime Mission, and that a ministry which, alike in its duration and fecundity, is unsurpassed in the religious history of mankind, was inaugurated. It was on that occasion that the “Most Great Spirit,” as designated by Bahá’u’lláh Himself, revealed itself to Him, in the form of a “Maiden,” and bade Him “lift up” His “voice between earth and heaven”—that same Spirit which, in the Zoroastrian, the Mosaic, the Christian, and Muḥammadan Dispensations, had been respectively symbolized by the “Sacred Fire,” the “Burning Bush,” the “Dove,” and the “Angel Gabriel.” “One night in a dream,” Bahá’u’lláh Himself, recounting His soul-shaking experience of the first stirrings of His prophetic Mission, in the Year Nine, in that abominable pit, has written, “these exalted words were heard on every side: ‘Verily, We shall render Thee victorious by Thyself and by Thy Pen. Grieve Thou not for that which hath befallen Thee, neither be Thou afraid, for Thou art in safety. Ere long will God raise up the treasures of the earth—men who will aid Thee through Thyself and through Thy Name, wherewith God hath revived the hearts of such as have recognized Him’.” And again, “During the days I lay in the prison of Ṭihrán, though the galling weight of the chains and the stench-filled air allowed Me but little sleep, still in those infrequent moments of slumber I felt as if something flowed from the crown of My head over My breast, even as a mighty torrent that precipitateth itself upon the earth from the summit of a lofty mountain. Every limb of My body would, as a result, be set afire. At such moments My tongue recited what no man could bear to hear.”
