17. In this way, some hours may be, and are, passed in prayer; for when the two faculties begin to drink deep, and to perceive the taste of this divine wine, they give themselves up with great readiness, in order to be the more absorbed: they follow the will, and the three rejoice together. But this state of complete absorption, together with the utter rest of the imagination,--for I believe that even the imagination is then wholly at rest,--lasts only for a short time; though the faculties do not so completely recover themselves as not to be for some hours afterwards as if in disorder: God, from time to time, drawing them to Himself. 18. Let us now come to that which the soul feels interiorly. Let him describe it who knows it; for as it is impossible to understand it, much more is it so to describe it. When I purposed to write this, I had just communicated, and had risen from the very prayer of which I am speaking. I am thinking of what the soul was then doing. Our Lord said to me: It undoes itself utterly, My daughter, in order that it may give itself more and more to Me: it is not itself that then lives, it is I. As it cannot comprehend what it understands, it understands by not understanding. [8] 19. He who has had experience of this will understand it in some measure, for it cannot be more clearly described, because what then takes place is so obscure. All I am able to say is, that the soul is represented as being close to God; and that there abides a conviction thereof so certain and strong, that it cannot possibly help believing so. All the faculties fail now, and are suspended in such a way that, as I said before, [9] their operations cannot be traced. If the soul is making a meditation on any subject, the memory of it is lost at once, just as if it had never been thought of. If it reads, what is read is not remembered nor dwelt upon; neither is it otherwise with vocal prayer. Accordingly, the restless little butterfly of the memory has its wings burnt now, and it cannot fly. The will must be fully occupied in loving, but it understands not how it loves; the understanding, if it understands, does not understand how it understands--at least, it can comprehend nothing of that it understands: it does not understand, as it seems to me, because, as I said just now, this cannot be understood. I do not understand it at all myself.
