A Persian prince expressed a desire to build “a duplicate of it [in his home in Kázimayn”, and Bahá’u’lláh’s reported remarks

It was this same reception room [of Bahá’u’lláh] which, in spite of its rude simplicity, had so charmed the Shujá‘u’d-Dawlih that he had expressed to his fellow-princes his intention of building a duplicate of it in his home in Káẓimayn. “He may well succeed,” Bahá’u’lláh is reported to have smilingly remarked when apprized of this intention, “in reproducing outwardly the exact counterpart of this low-roofed room made of mud and straw with its diminutive garden. What of his ability to open onto it the spiritual doors leading to the hidden worlds of God?”

The “Most Great House”: - the “dilapidated”, “Low-roofed” room “, “set apart for the reception of Bahá’u’lláh’s visitors”; “a single couch, fashioned from the branches of palms”: - “vied…with the Most Exalted Paradise”

“The room of the Most Great House,” that same chronicler [Nabil] has recorded, “set apart for the reception of Bahá’u’lláh’s visitors, though dilapidated, and having long since outgrown its usefulness, vied, through having been trodden by the blessed footsteps of the Well Beloved, with the Most Exalted Paradise. Low-roofed, it yet seemed to reach to the stars, and though it boasted but a single couch, fashioned from the branches of palms, whereon He Who is the King of Names was wont to sit, it drew to itself, even as a loadstone, the hearts of the princes.”

The incredible “burning devotion” that Bahá’u’lláh’s “love had kindled” in the “souls” of “His companions”

The complete transformation which the written and spoken word of Bahá’u’lláh had effected in the outlook and character of His companions was equalled by the burning devotion which His love had kindled in their souls. A passionate zeal and fervor, that rivalled the enthusiasm that had glowed so fiercely in the breasts of the Báb’s disciples in their moments of greatest exaltation, had now seized the hearts of the exiles of Baghdád and galvanized their entire beings. “So inebriated,” Nabíl, describing the fecundity of this tremendously dynamic spiritual revival, has written, “so carried away was every one by the sweet savors of the Morn of Divine Revelation that, methinks, out of every thorn sprang forth heaps of blossoms, and every seed yielded innumerable harvests.”

The amazing way in which “most of those who surrounded Bahá’u’lláh” in Baghdád decided to help each other to maintain strict spiritual discipline

“Most of those who surrounded Bahá’u’lláh,” wrote Nabíl, describing the spirit that animated the reformed Bábí community in Baghdád, “exercised such care in sanctifying and purifying their souls, that they would suffer no word to cross their lips that might not conform to the will of God, nor would they take a single step that might be contrary to His good-pleasure.” “Each one,” he relates, “had entered into a pact with one of his fellow-disciples, in which they agreed to admonish one another, and, if necessary, chastise one another with a number of blows on the soles of the feet, proportioning the number of strokes to the gravity of the offense against the lofty standards they had sworn to observe.” Describing the fervor of their zeal, he states that “not until the offender had suffered the punishment he had solicited, would he consent to either eat or drink.”

An example of how Bahá’u’lláh stressed “His strong condemnation of all acts of violence”

In another connection He, wishing to stress His strong condemnation of all acts of violence, had written: “It would be more acceptable in My sight for a person to harm one of My own sons or relatives rather than inflict injury upon any soul.”
