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.
