During the latter days [passed] in Adrianople Bahá’u’lláh composed a detailed epistle setting forth all matters clearly and minutely. He unfolded and expounded the main principles of the sect, and made clear and plain its ethics, manners, course, and mode of conduct: He treated certain political questions in detail, and adduced sundry proofs of His truthfulness: He declared the good intent, loyalty, and sincerity of the sect, and wrote some fragments of prayers, some in Persian, but the greater part in Arabic. He then placed it in a packet and adorned its address with the royal name of His Majesty the King of Persia, and wrote [on it] that some person pure of heart and pure of life, dedicated to God, and prepared for martyr-sacrifice, must, with perfect resignation and willingness, convey this epistle into the presence of the King.
A youth named Mírzá Badí, a native of Khurásán, took the epistle, and hastened toward the presence of His Majesty the King. The Royal Train had its abode and station outside Tihrán, so he took his stand alone on a rock in a place far off but opposite to the Royal Pavilion, and awaited day and night the passing of the Royal escort or the attainment of admission into the Imperial Presence. Three days did he pass in a state of fasting and vigilance: an emaciated body and enfeebled spirit remained. On the fourth day the Royal Personage was examining all quarters and directions with a telescope when suddenly his glance fell on this man who was seated in the utmost respectful attitude on a rock. It was inferred from the indications [perceived] that he must certainly have thanks [to offer], or some complaint or demand for redress and justice [to prefer].
