These two large basins can be filled with water in different ways: the water in the one comes from a long distance, by means of numerous conduits and through human skill; but the other has been constructed at the very source of the water and fills without making any noise. If the flow of water is abundant, as in the case we are speaking of, a great stream still runs from it after it has been filled; no skill is necessary here, and no conduits have to be made, for the water is flowing all the time. The difference between this and the carrying of the water by means of conduits is, I think, as follows. The latter corresponds to the spiritual sweetness which, as I say, is produced by meditation. It reaches us by way of the thoughts; we meditate upon created things and fatigue the understanding; and when at last, by means of our own efforts, it comes, the satisfaction which it brings to the soul fills the basin, but in doing so makes a noise, as I have said.
