414. So that a third of the day did not shine, and likewise the night. This symbolically means that they no longer have in them any spiritual truth or natural truth from the Word serviceable for doctrine and life.

The day's not shining means that they had no light from the sun, and "likewise the night" means that they had no light from the moon and stars. Light in general symbolizes Divine truth, which is truth from the Word. The light of the sun symbolizes spiritual Divine truth, and the light of the moon and stars symbolizes natural Divine truth, both acquired from the Word. Divine truth in the spiritual sense of the Word is like the light of the sun during the day, and Divine truth in the natural sense of the Word is like the light of the moon and stars at night. The spiritual sense of the Word, moreover, flows into its natural sense, as the sun does with its light to the moon, and this reflects the light of the sun indirectly.

In this way also does the spiritual sense of the Word enlighten people, even people who know nothing of that sense, when they read the Word in its natural sense. However, it enlightens a spiritual person as light from the sun does his eye, but a natural person as light from the moon and stars does his eye. Everyone is enlightened in accordance with his spiritual affection for truth and goodness, and at the same time in accordance with the genuine truths by which he has opened his rational faculty.

[2] Day and night also have this meaning in the following places:

God said, "Let there be lights in the firmament of the heavens to divide the day from the night...." Then God made two great lights: the greater light to rule by day, and the lesser light to rule by night. He made the stars also. And God set them in the firmament of the heavens to give light on the earth, and to rule by day and by night, and to divide the light from the darkness. (Genesis 1:14-19)

(Jehovah) made great lights..., the sun to rule by day..., the moon and stars to rule by night... (Psalms 136:7-9)

The day is Yours, (O Jehovah,) the night also is Yours; You have prepared the light and the sun. (Psalms 74:16)

...Jehovah... gives the sun for a light by day, the ordinances of the moon and the stars for a light by night... (Jeremiah 31:35)

If you can break My covenant with the day and My covenant with the night, so that there will not be day and night in their season, then My covenant also may be broken with David My servant... If I have not appointed My covenant with day and night, the ordinances of heaven and earth, I also will reject the offspring of Jacob and David... (Jeremiah 33:20-21, 25-26)

I cite these passages to make known that the darkening of both kinds of light is meant.

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.
