A cataclysmic process, one of the most remarkable in modern history, was set in motion ever since Bahá’u’lláh, while a prisoner in Constantinople, delivered to a Turkish official His Tablet, addressed to Sultán ‘Abdu’l-‘Azíz and his ministers, to be transmitted to ‘Alí Páshá, the Grand Vizir. It was this Tablet which, as attested by that officer and affirmed by Nabíl in his chronicle, affected the Vizir so profoundly that he paled while reading it.
