One day they summoned Him[the Báb] to the mosque urging and constraining Him to recant, but He discoursed from the pulpit in such wise as to silence and subdue those present and to stablish and strengthen His followers. It was then supposed that He claimed to be the medium of grace from His Highness the Lord of the Age (upon Him be peace); but afterwards it became known and evident that His meaning was the Gatehood [Bábíyyat] of another city and the mediumship of the graces of another Person Whose qualities and attributes were contained in His books and treatises. (‘Abdu’l-Baha, ‘A Traveler’s Narrative’)
