7442. And the houses of the Egyptians shall be filled with the noisome fly, and also the land whereon they are. That this signifies that the falsities of malevolence will take possession of all things of the natural mind, is evident from the signification of "filling," as being to take possession of; from the signification of "the house of the Egyptians," as being the interiors of the natural mind (of which above, n. 7407); from the signification of "the noisome fly," as being falsities of malevolence (of which just above, n. 7441); and from the signification of "the land of Egypt," as being the natural mind in general (see n. 5276, 5278, 5280, 5288, 5301). [2] How it is that the interiors also of the natural mind shall be taken possession of by the falsities of evil which are in the outermost parts of this mind, must be briefly told. The things that flow in with man through heaven from the Lord, flow into his interiors, and advance down to the ultimates or outermost parts, and there they are presented to man in a sensible form, consequently they flow down into the sensuous, and through this into the things of the body. If the sensuous has been filled with phantasies from fallacies and appearances, and especially if it has been filled with phantasies from falsities, then the truths which flow in are there turned into similar things, for they are received there according to the form that is induced on them (see n. 7343). Insofar also as truths are turned into falsities, so far the interiors through which they pass are closed, and at last there is no opening beyond that which is necessary for a sufficient transflux to confer the faculty of reasoning, and of confirming evils by means of falsities. [3] Such being the case with man, it must needs be that while he is being regenerated his natural must be regenerated down to the sensuous; for unless this is regenerated, there is no reception of truth and good, because, as before said, the inflowing truth is there perverted, and then the interiors are closed. And therefore when the exteriors have been regenerated, the whole man has been regenerated, as was signified by the Lord's words to Peter when He washed his feet:
Simon Peter said unto Him, Lord, wash Thou not my feet only, but also my hands and my head. Jesus said to him, He that hath been bathed needeth not save to have his feet washed, and is clean every whit (John 13:9-10);
by the "feet" are signified natural things (n. 2162, 3761, 3986, 4280, 4938-4952); by "washing" is signified purifying (n. 3147, 5954); by "hands" are signified the interiors of the natural; and by the "head" spiritual things; hence is plain what is meant by "him that hath been bathed needing only to have his feet washed, and being clean every whit," namely, that a man has already been regenerated when he has been regenerated also in respect to the exteriors that belong to the natural. When therefore man has been regenerated also in respect to the natural, then all things therein have been made subordinate to the more interior things; and when these flow in there, they flow as into their generals, by which they present themselves to man in a sensible form. When this is the case with a man, he sensibly feels the affection of the truth that is of faith, and the affection of the good that is of charity. [4] But the sensuous itself, which is the ultimate of the natural, can with difficulty be regenerated, because it has been filled with material ideas from things earthly, bodily, and worldly. Therefore the man who is being regenerated, especially at this day, is not regenerated as to the sensuous, but as to the natural which is next above the sensuous, to which he is elevated by the Lord from the sensuous, when he is thinking about the truths and goods of faith. The man who is being regenerated by the Lord is endowed with the capacity of elevation from the sensuous. With respect to the nature of the sensuous, and the elevation of the thought above it, see n. 5084, 5089, 5094, 5125, 5128, 5767, 6183, 6201, 6310, 6311, 6313, 6314, 6316, 6318, 6564, 6598, 6612, 6614, 6622, 6624, 6844, 6845, 6948, 6949.)
