“… one of Bahá’u’lláh’s greatest miracles” – ‘Abdu’l-Baha explains

Although the policy of Sultán ‘Abdu’l-Hamíd was harsher than ever; although he constantly insisted on his Captive’s strict confinement—still, the Blessed Beauty now lived, as everyone knows, with all power and glory. Some of the time Bahá’u’lláh would spend at the Mansion, and again, at the farm village of Mazra’ih; for a while He would sojourn in Haifa, and occasionally His tent would be pitched on the heights of Mount Carmel. Friends from everywhere presented themselves and gained an audience. The people and the government authorities witnessed it all, yet no one so much as breathed a word. And this is one of Bahá’u’lláh’s greatest miracles: that He, a captive, surrounded Himself with panoply and He wielded power. The prison changed into a palace, the jail itself became a Garden of Eden. Such a thing has not occurred in history before; no former age has seen its like: that a man confined to a prison should move about with authority and might; that one in chains should carry the fame of the Cause of God to the high heavens, should win splendid victories in both East and West, and should, by His almighty pen, subdue the world. Such is the distinguishing feature of this supreme Theophany. (‘Abdu’l-Baha, ‘Memorials of the Faithful’)
