"The world will pass away, and so will all the things whereat your hearts rejoice, or wherein ye pride yourselves before men. Cleanse the mirrors of your hearts from the dross of the world and all that is therein, that they may reflect the resplendent light of God. This, indeed, shall enable you to dispense with all save God, and to attain unto the good pleasure of your Lord, the Most Bountiful, the All-Knowing, the All-Wise. We, verily, have unfolded before your eyes that which shall profit you both in this world and in the realm of faith, and which will lead you to the path of salvation. Would that ye might turn thereunto!"
