16. And being admonished by these books to return into myself, I entered into my inward soul, guided by thee. This I could do because thou wast my helper. And I entered, and with the eye of my soul--such as it was--saw above the same eye of my soul and above my mind the Immutable Light. It was not the common light, which all flesh can see; nor was it simply a greater one of the same sort, as if the light of day were to grow brighter and brighter, and flood all space. It was not like that light, but different, yea, very different from all earthly light whatever. Nor was it above my mind in the same way as oil is above water, or heaven above earth, but it was higher, because it made me, and I was below it, because I was made by it. He who knows the Truth knows that Light, and he who knows it knows eternity. Love knows it, O Eternal Truth and True Love and Beloved Eternity! Thou art my God, to whom I sigh both night and day. When I first knew thee, thou didst lift me up, that I might see that there was something to be seen, though I was not yet fit to see it. And thou didst beat back the weakness of my sight, shining forth upon me thy dazzling beams of light, and I trembled with love and fear. I realized that I was far away from thee in the land of unlikeness, as if I heard thy voice from on high: "I am the food of strong men; grow and you shall feed on me; nor shall you change me, like the food of your flesh into yourself, but you shall be changed into my likeness." And I understood that thou chastenest man for his iniquity, and makest my soul to be eaten away as though by a spider. And I said, "Is Truth, therefore, nothing, because it is not diffused through space--neither finite nor infinite?" And thou didst cry to me from afar, "I am that I am." And I heard this, as things are heard in the heart, and there was no room for doubt. I should have more readily doubted that I am alive than that the Truth exists--the Truth which is "clearly seen, being understood by the things that are made."
