Bahá’u’lláh: The Hidden Words, Part Two (Persian), No. 74

O Children of Vainglory! For a fleeting sovereignty ye have abandoned My imperishable dominion, and have adorned yourselves with the gay livery of the world and made of it your boast. By My beauty! All will I gather beneath the one-colored covering of the dust and efface all these diverse colors save them that choose My own, and that is purging from every color.
