Therefore, O Tat my Son, you must pray first to the Lord and Father; to the Alone and the One, from whom is one to be merciful to you, that you may know and understand so great a God. Pray that he would shine one of his beams on you in your understanding. 10. For only the Understanding see that which is not manifest, or apparent, as being itself not manifest or apparent; and if you can, O Tat, it will appear to the eyes of your Mind.
