He Begs of God that He May Live in the True Light, and May Be Instructed as to the Mysteries of the Sacred Books
10 Oh, let Truth, the light of my heart, not my own darkness, speak unto me! I have descended to that, and am darkened. But thence, even thence, did I love You. I went astray, and remembered You. I heard Your voice behind me bidding me return, and scarcely did I hear it for the tumults of the unquiet ones. And now, behold, I return burning and panting after Your fountain. Let no one prohibit me; of this will I drink, and so have life. Let me not be my own life; from myself have I badly lived—death was I unto myself; in You do I revive. Speak unto me; discourse unto me. In Your books have I believed, and their words are very deep.
