4 O thou who hast set foot in the wilderness of knowledge and taken abode within the ark of wisdom! Not until thou hast grasped the mysteries concealed in that which We shall relate unto thee canst thou hope to attain to the stations of faith and certitude in the Cause of God and in those who are the Manifestations of His Cause, the Daysprings of His Command, the Treasuries of His revelation, and the Repositories of His knowledge. Shouldst thou fail in this, thou wouldst be numbered with them that have not striven for the Cause of God, nor inhaled the fragrance of faith from the raiment of certitude, nor scaled the heights of the divine unity, nor yet recognized the stations of divine singleness within the Embodiments of praise and the Essences of sanctity. 5 Strive then, O My brother, to apprehend this matter, that the veils may be lifted from the face of thy heart and that thou mayest be reckoned among them whom God hath graced with such penetrating vision as to behold the most subtle realities of His dominion, to fathom the mysteries of His kingdom, to perceive the signs of His transcendent Essence in this mortal world, and to attain a station wherein one seeth no distinction amongst His creatures and findeth no flaw in the creation of the heavens and the earth.(3) 6 Now that the discourse hath reached this exalted and intractable theme and touched upon this sublime and impenetrable mystery, know that the Christian and Jewish peoples have not grasped the intent of the words of God and the promises He hath made to them in His Book, and have therefore denied His Cause, turned aside from His Prophets, and rejected His proofs. Had they but fixed their gaze upon the testimony of God itself, had they refused to follow in the footsteps of the abject and foolish among their leaders and divines, they would doubtless have attained to the repository of guidance and the treasury of virtue, and quaffed from the crystal waters of life eternal in the city of the All-Merciful, in the garden of the All-Glorious, and within the inner reality of His paradise. But as they have refused to see with the eyes wherewith God hath endowed them, and desired things other than that which He in His mercy had desired for them, they have strayed far from the retreats of nearness, have been deprived of the living waters of reunion and the wellspring of His grace, and have lain as dead within the shrouds of their own selves.
