Kitab-i-Aqdas/Elder163

The one who does not attain unto this lofty principle and this most high Station is moved by the winds of doubt and the statements of the polytheists upset him. Whoever has attained unto this principle has attained unto the greatest uprightness. Very good indeed is this most splendid Station by the remembrance of which every inaccessible Tablet is adorned. Thus God teaches you what will deliver you from doubt and perplexity and save you in this world and that which is to come. He is the Generous Forgiver. It is He who sent the Messengers and sent down the Books since, "There is no god besides Me, the Powerful, the Wise."
