He is Glad that God Dwells in His Memory
36 But where in my memory do You abide, O Lord? Where do You there abide? What manner of chamber have You there formed for Yourself? What sort of sanctuary have You erected for Yourself? You have granted this honour to my memory, to take up Your abode in it; but in what quarter of it You abide, I am considering. For in calling You to mind, I soared beyond those parts of it which the beasts also possess, since I found You not there among the images of corporeal things; and I arrived at those parts where I had committed the affections of my mind, nor there did I find You.
And I entered into the very seat of my mind, which it has in my memory, since the mind remembers itself also— nor were You there. For as You are not a bodily image, nor the affection of a living creature, as when we rejoice, condole, desire, fear, remember, forget, or anything of the kind; so neither are You the mind itself, because You are the Lord God of the mind; and all these things are changed, but You remain unchangeable over all, yet vouchsafe to dwell in my memory, from the time I learned You. But why do I now seek in what part of it You dwell, as if truly there were places in it? You dwell in it assuredly, since I have remembered You from the time I learned You, and I find You in it when I call You to mind.
