A few days later, Mullá Ḥusayn left for [_Kh_]urásán. As he bade me farewell, he said: 'Breathe not to anyone what you have heard and witnessed. Let this be a secret hidden within your breast. Divulge not His name, for they who envy His position will arise to harm Him. In your moments of meditation, pray that the Almighty may protect Him, that, through Him, He may exalt the downtrodden, enrich the poor, and redeem the fallen. The secret of things is concealed from our eyes. Ours is the duty to raise the call of the New Day and to proclaim this Divine Message unto all people. Many a soul will, in this city, shed his blood in this path. That blood will water the Tree of God, will cause it to flourish, and to overshadow all mankind.'[6] [Footnote BA: Teacher or tutor.] [Footnote BB: Bahá'u'lláh's father was famed for his calligraphy.] From Ma[_sh_]had, the holy city that has within it the Shrine of the eighth Imám, Mullá Ḥusayn addressed his first letter to the Báb. He gave, as instructed by Him, the full details of his journey from [_Sh_]íráz to [_Kh_]urásán. He presented the list of names of those who had responded to the call of the new theophany: a list which had become further enriched in [_Kh_]urásán by the enrolment of Mírzá Aḥmad-i-Az[_gh_]andí, the most learned of the divines of that renowned province; Mullá Mírzá Muḥammad-i-Furú[_gh_]í, another divine of immense learning; Mírzá Muḥammad-Báqir-i-Qá'iní, whose house in Ma[_sh_]had was to gain the distinction of being known as the Bábíyyih, since its doors would be always open to those who sought Mullá Ḥusayn and to all the Bábís; Mullá Aḥmad-i-Mu`allim, who had been a tutor to the sons of Siyyid Káẓim; and Mullá [_Sh_]ay[_kh_] `Alí, to whom the Báb gave the title of `Aẓím (Great). But above all, Mullá Ḥusayn recounted what had transpired in Ṭihrán, culminating in the gracious response of the nobleman of Núr. He sent his letter, again as instructed by the Báb, to Ṭabas (a town in the province of [_Kh_]urásán) where agents of Ḥájí Mírzá Siyyid `Alí received it and dispatched it to Yazd, whence it reached [_Sh_]íráz. The arrival of Mullá Ḥusayn's letter and the tidings which it conveyed brought unbounded joy to the Báb. Soon after, in the month of September, He left [_Sh_]íráz, accompanied by Quddús, and the faithful Ethiopian servant, Mubárak. From Bú[_sh_]ihr, while waiting to take the boat to Jiddah (Jaddah), the Báb wrote His first letter to His wife. It opens with these moving words:
