To the care of Mullá Husayn He [the Báb] committed a
mission, more specific in character and mightier in import. He affirmed that
His covenant with him had been established, cautioned him to be forbearing with
the divines he would encounter, directed him to proceed to Tihrán, and alluded,
in the most glowing terms, to the as yet unrevealed Mystery enshrined in that
city—a Mystery that would, He affirmed, transcend the light shed by both Hijáz
and Shíráz.
