“I am the Mystic Fane,” the Báb thus proclaims His station in the Qayyúmu’l-Asmá, “which the Hand of Omnipotence hath reared. I am the Lamp which the Finger of God hath lit within its niche and caused to shine with deathless splendor. I am the Flame of that supernal Light that glowed upon Sinai in the gladsome Spot, and lay concealed in the midst of the Burning Bush.” “O Qurratu’l-‘Ayn!” He, addressing Himself in that same commentary, exclaims, “I recognize in Thee none other except the ‘Great Announcement’—the Announcement voiced by the Concourse on high. By this name, I bear witness, they that circle the Throne of Glory have ever known Thee.” 
(Shoghi Effendi, ‘The Dispensation of Baha’u’llah’)
