The Báb asks Baha’u’llah: - to “reveal from the heights of the Most Lofty and Mystic Mount a faint, an infinitesimal glimmer of Thy impenetrable Mystery”

“And when the appointed hour hath struck,” He [the Báb] again addresses Bahá’u’lláh in that same commentary, [the Qayyúmu’l-Asmá] “do Thou, by the leave of God, the All-Wise, reveal from the heights of the Most Lofty and Mystic Mount a faint, an infinitesimal glimmer of Thy impenetrable Mystery, that they who have recognized the radiance of the Sinaic Splendor may faint away and die as they catch a lightening glimpse of the fierce and crimson Light that envelops Thy Revelation.”
