Returning to this verse, what it says about the enlargement of the heart may, I think, be of some help to us. For apparently, as this heavenly water begins to flow from this source of which I am speaking -- that is, from our very depths -- it proceeds to spread within us and cause an interior dilation and produce ineffable blessings, so that the soul itself cannot understand all that it receives there. The fragrance it experiences, we might say, is as if in those interior depths there were a brazier on which were cast sweet perfumes; the light cannot be seen, nor the place where it dwells, but the fragrant smoke and the heat penetrate the entire soul, and very often, as I have said, the effects extend even to the body. Observe -- and understand me here -- that no heat is felt, nor is any fragrance perceived: it is a more delicate thing than that; I only put it in that way so that you may understand it. People who have not experienced it must realize that it does in very truth happen; its occurrence is capable of being perceived, and the soul becomes aware of it more clearly than these words of mine can express it. For it is not a thing that we can fancy, nor, however hard we strive, can we acquire it, and from that very fact it is clear that it is a thing made, not of human metal, but of the purest gold of Divine wisdom. In this state the faculties are not, I think, in union, but they become absorbed and are amazed as they consider what is happening to them.
