“By the righteousness of God!” writes Bahá’u’lláh, “The world, its vanities and its glory, and whatever delights it can offer, are all, in the sight of God, as worthless as, nay even more contemptible than, dust and ashes. Would that the hearts of men could comprehend it. Wash yourselves thoroughly, O people of Bahá, from the defilement of the world, and of all that pertaineth unto it. God Himself beareth Me witness! The things of the earth ill beseem you. Cast them away unto such as may desire them, and fasten your eyes upon this most holy and effulgent Vision.” “O ye My loved ones!” He thus exhorts His followers, “Suffer not the hem of My sacred vesture to be smirched and mired with the things of this world, and follow not the promptings of your evil and corrupt desires.” And again, “O ye the beloved of the one true God! Pass beyond the narrow retreats of your evil and corrupt desires, and advance into the vast immensity of the realm of God, and abide ye in the meads of sanctity and of detachment, that the fragrance of your deeds may lead the whole of mankind to the ocean of God’s unfading glory.” “Disencumber yourselves,” He thus commands them, “of all attachment to this world and the vanities thereof. Beware that ye approach them not, inasmuch as they prompt you to walk after your own lusts and covetous desires, and hinder you from entering the straight and glorious Path.” “Eschew all manner of wickedness,” is His commandment, “for such things are forbidden unto you in the Book which none touch except such as God hath cleansed from every taint of guilt, and numbered among the purified.” “A race of men,” is His written promise, “incomparable in character, shall be raised up which, with the feet of detachment, will tread under all who are in heaven and on earth, and will cast the sleeve of holiness over all that hath been created from water and clay.” “The civilization,” is His grave warning, “so often vaunted by the learned exponents of arts and sciences, will, if allowed to overleap the bounds of moderation, bring great evil upon men.... If carried to excess, civilization will prove as prolific a source of evil as it had been of goodness when kept within the restraints of moderation.” “He hath chosen out of the whole world the hearts of His servants,” He explains, “and made them each a seat for the revelation of His glory. Wherefore, sanctify them from every defilement, that the things for which they were created may be engraven upon them. This indeed is a token of God’s bountiful favor.” “Say,” He proclaims, “He is not to be numbered with the people of Bahá who followeth his mundane desires, or fixeth his heart on things of the earth. He is My true follower who, if he come to a valley of pure gold will pass straight through it aloof as a cloud, and will neither turn back, nor pause. Such a man is assuredly of Me. From his garment the Concourse on high can inhale the fragrance of sanctity....
