The people of Núr, when Bahá’u’lláh had departed from out
their midst, continued to propagate the Cause and to consolidate its
foundations. A number of them endured the severest afflictions for His sake;
others quaffed with gladness the cup of martyrdom in His path. Mázindarán in
general, and Núr in particular, were thus distinguished from the other
provinces and districts of Persia, as being the first to have eagerly embraced
the Divine Message. The district of Núr, literally meaning “light,” which lay
embedded within the mountains of Mázindarán, was the first to catch the rays of
the Sun that had arisen in Shíráz, the first to proclaim to the rest of Persia,
which still lay enveloped in the shadow of the vale of heedlessness, that the
Day-Star of heavenly guidance had at length arisen to warm and illuminate the
whole land.
