Madinatut-Tawhid/English9

So bear witness, O Salman, that in the treasuries of God's knowledge there are sciences that have never been mentioned, the knowledge of none, the unification by which God's servants unify Him, nor the highest jewels of individualism. But when His mercy preceded all creation, He accepts from them what He commands them in the time of each messenger and in the covenant of each prophet, as a favor from Him to all creatures. So testify that there is no god but Him, and that no one will know Him, and that no one will reach the beginnings of His knowledge; neither will any soul comprehend Him nor anyone in the kingdom know Him.

Indeed, you are among those who seek mysteries in the matter. If only there were sanctuaries and pure hearts to fly with this servant in the air of this science, which burned the wings of those who approached it. God will manifest on earth servants who will not be held back by prohibition, and they will fly with the wing of sanctity, and walk in the kingdoms of eternity, and enter the luminous pavilion of honor. They will not be preoccupied with any matter in the kingdom, nor will the adornments of the earth distract them from the remembrance of the exalted, mighty, powerful God.

When they hear the melodies of the soul, their eyes overflow with tears, and they rejoice in the spirit of God, and they turn towards the beauty of a unique sanctuary. They will not exchange the verses of God for anything, even if they spend all that is in the heavens and the earth. Whenever they hear the melodies of God, they incline towards the homeland of nearness and devote themselves at all times. At that time, it is appropriate to begin mentioning what I intended before and to complete this remembrance, which will not reach the hearts of those who have reached it.
