Say: O children of dust! He Who is the Spirit of Purity saith: In this glorious Day whatsoever can purge you from defilement and ensure your peace and tranquillity, that indeed is the straight Path, the Path that leadeth unto Me. To be purged from defilement is to be cleansed of that which is injurious to man and detracteth from his high station—among which is to take undue pleasure in one’s own words and deeds, notwithstanding their unworthiness. True peace and tranquillity will only be realized when every soul will have become the well-wisher of all mankind. He Who is the All-Knowing beareth Me witness: were the peoples of the world to grasp the true significance of the words of God, they would never be deprived of their portion of the ocean of His bounty. In the firmament of truth there hath never been, nor will there ever be, a brighter star than this.
