During this period Mírzá Yahyá remained concealed and hidden, continuing and abiding in his former conduct and behavior, until, when the edict for the removal of Bahá’u’lláh from Baghdád was issued by His Majesty the Ottoman monarch, Mírzá Yahyá would neither quit nor accompany [Him]: at one time he meditated setting out for India, at another settling in Turkistán; but, being unable to decide on either of these two plans, he finally, at his own wish, set out before all in the garb of a dervish, in disguise and change of raiment, for Kárkúk and Arbíl. Thence, by continuous advance, he reached Mosul, where, on the arrival of the main body, he took up his abode and station alongside their caravan. And although throughout this journey the governors and officials observed the utmost consideration and respectfulness, while march and halt were alike dignified and honorable, nevertheless was he always concealed in change of raiment, and acted cautiously, on the idea that some act of aggression was likely to occur.
