7442. 'And the houses of the Egyptians will be full of the noxious flying insects, and also the land on which they are' means that malevolent falsities will take possession of everything in the natural mind. This is clear from the meaning of 'filling' as taking possession of; from the meaning of 'the houses of the Egyptians' as the interior parts of the natural mind, dealt with above in 7407; from the meaning of 'noxious flying insects' as malevolent falsities, dealt with immediately above in 7441; and from the meaning of 'the land of Egypt' as the natural mind in general, dealt with in 5276, 5178, 5180, 5288, 5301.

[2] A brief statement needs to be made about what is implied in the meaning here - by the idea that even the interior parts of the natural mind will be taken possession of by the falsities arising from evil which are present in the outermost parts of that mind. What a person has flowing into him from the Lord by way of heaven flows into the interior parts of him, and then spreads right down to the lowest or outermost levels, where he becomes conscious of it. Consequently it comes right down into the level of the senses, and through this into parts of the body. If the level of the senses is filled with mistaken ideas based on illusions and appearances, and especially if they are based on falsities, the truths that flow in are turned there into similar ideas, since they are received there in accordance with the form imposed on them, see 7743. Also to the extent that truths are turned into falsities the interior parts of the mind serving as channels for the passage of truths are closed. Eventually the opening is only just large enough for the smallest amount of influx that the person needs to engage in reasoning and to use falsities to justify evils.

[3] This being the situation with a person, it is necessary when he is being regenerated for his natural to be regenerated right down to the sensory level. For unless that level is regenerated no reception of truth and good takes place, because - as stated above - truth that is flowing in is perverted there and the interiors parts are in those circumstances closed. Consequently when the exterior parts have been regenerated the whole person has been regenerated. This was what the Lord meant by His words to Peter when He washed his feet, in John,

Simon Peter said, Lord, You are not to wash my feet only, but also my hands and head. Jesus said to him, He who has been washed has no need except to wash his feet, and the whole person is clean. John 13:9-10.

'Feet' means the parts forming the natural, 2162, 3761, 3986, 4280, 4938-4952; 'washing' means purifying, 3147, 5954 (end); 'hands' means the interior parts of the natural; and 'head' means the parts forming the spiritual. These meanings show what precisely one should understand by 'he who has been washed has no need except to wash his feet, and the whole person is clean' - that a person has been regenerated when even the exterior parts forming the natural have been regenerated. When therefore a person has had even his natural regenerated everything on that level is subordinated to more internal levels. And when the contents of the more internal levels enter they flow into images on that level which serve as the general vessels to contain them, and through those images the person is made conscious of them. When this is the situation with a person, he has conscious feelings of an affection for the truth of faith and of an affection for the good of charity.

[4] But it is difficult for the actual level of the senses, which is the lowest of the natural, to be regenerated, because it is completely filled with material ideas formed from earthly, bodily, and worldly things. For this reason a person who is being regenerated, especially at the present day, does not undergo regeneration at the sensory level, only at the natural level immediately above it, to which the Lord raises him from the level of the senses when he thinks about the truths and forms of the good of faith. The ability to be raised from the sensory level is what is imparted to the person who is being regenerated by the Lord. Regarding what the sensory level is like, and the raising of thought above it, see 5084, 5089, 5094, 5125, 5118, 5767, 6183, 6201, 6310, 6311, 6598, 6612, 6614, 6622, 6624, 6844, 6845, 6948.

5089. 'And they were in custody for days' means that they lay in a state when they were cast aside for a long time. This is clear from the meaning of 'days' as states, dealt with in 23, 487, 488, 493, 893, 2788, 3462, 3785, 4850; so that 'for days' here means lying in a particular state for a long time - in a state when they were cast aside, meant by 'custody', 5083. A more lengthy explanation of the details contained in the internal sense here is not possible because they are not the kind of matters about which any idea can be gained with the help of things in the world, such as details about the celestial-of-the-spiritual man, about this man's state within the natural when the interior natural is being made new, and after that when it has been made new and the exterior natural has been cast aside. But some idea of these matters and others like them can be gained from things in heaven, which is the kind of idea that does not pass into any notion gained from things in the world, except in the case of people who, in their thinking, can be led away from sensory impressions.

[2] Unless a person's thought can be raised above sensory impressions so that these are beheld as existing so to speak beneath him, he cannot possibly discern any interior aspect of the Word, let alone things of heaven such as are totally removed from those of the world, since the senses take hold of them and stifle them. This explains why people who rely on their senses and have focused their attention on known facts rarely understand anything about the things of heaven; for they have immersed their thoughts in the kinds of things that belong to the world, that is, in terms and in definitions formed from these, and so in what the senses perceive, from which they can no longer be raised up and so preserved in a way of looking at things that is higher than the senses. Nor can their thought range freely any longer over the whole field of matters recorded in the memory, selecting those which agree and casting aside those which are contrary, and using those which are in any way appropriate. For their thought is locked up and immersed in terms, as has been stated, and consequently in sensory impressions, so that it cannot look round about. This is the reason why the learned possess less belief than the simple, and also indeed why they possess less discernment in heavenly matters. For the simple can view something from a position that is above mere terms and above known facts, and so above sensory evidence. This the learned cannot do; their viewpoint is based on terms and known facts because their mind is immersed in these. Thus they are bound so to speak in a dungeon or prison.
