The Lord is life itself. We are recipients of life. We give life unique forms because of our unique shapes as receptacles, and through free will we can choose how fully we will receive life. But we don't have life of our own. It follows from this that the more we turn toward the Lord and receive life, the more alive we will be; and the more we turn away the more dead we will be. It also follows that believing life is our own – with all the loves, the thoughts and the power that entails – is actually the antithesis of life.

This is the state of those in the deepest hells, who reject everything of the Lord, even His existence, and claim all life as their own. They are, in fact, only alive because the Lord forces life on them in the amount necessary to sustain existence.

This is, in a sense, what is represented by the rib – which is human, and is alive, but only in the most limited way. When the people of the Most Ancient Church (Adam) wanted to lead themselves and sense life as their own, the Lord had to use that most dead aspect of them to grant their wish. He had to use that bone, which represents our most hellish potential, what we would be if we were to reject the Lord completely.

But then the Lord did something miraculous. He turned that bone into living flesh, into a new person: the woman Eve. This represents that the Lord built that most dead, most hellish aspect of us up into something which felt life as its own, but could acknowledge that life actually came from the Lord, and could thus again be a recipient of life. It wasn't quite as pure as before; people could no longer commune directly with the Lord. But they had what they wanted instead: a sense of self.

The Writings call this – both the rib and the woman – by the Latin word proprium, essentially meaning "as of self." The rib represents the proprium on its own, which is hellish. The woman represents the proprium given life by the Lord.

8137. And I will be glorified. That this signifies that they should see a Divine effect from the Divine Human of the Lord in the dissipation of falsity, is evident from the signification of “to be glorified,” when said of Jehovah or the Lord, as being a Divine effect, here from His Divine Human, because by coming into the world and assuming the Human and making it Divine, the Lord cast into the hells all evils and falsities, and reduced the heavens into order, and also liberated from damnation those who were of the spiritual church (see n. 6854, 6914, 7091, 7828, 7932, 8018). These things are in general signified by “being glorified,” but here there is signified that they who had infested the well-disposed should be cast into hell, and there encompassed about with falsities as with waters of a sea, and this as a Divine effect from the mere presence of the Lord.

[2] To show how the case herein is, it shall be further unfolded. There are as many hells as there are genera and species of evils, each hell being separated from others as it were by rain-storms, clouds, or waters. In the other life evils and falsities appear before the eyes of spirits as rain-storms and clouds, and also as waters; the falsities from evils of those who have been of the spiritual church and have lived evilly, appear as waters; but the falsities from evils of those who have been of the celestial church, appear as rain-storms. They who are in the hells appear to be thus encompassed, with a difference everywhere in respect to amount and kind, density and rarity, thick darkness and dimness, according to the genus and species of the falsity from evil. The hell where they are who have lived in faith separate from charity and in a life of evil, is encompassed as by the waters of a sea; the falsities of evil do not indeed appear as waters to those who are there, but to those who look from without. Above that sea, where these are, are the hells of adulterers; these are above, because in the internal sense adulteries denote adulterations of good and the consequent perversions of truth, thus they denote evils from which come falsities contrary to the truths and goods of faith (n. 2466, 2729, 3399), being such falsities as are with those who are in the hell beneath, and who have lived contrary to the truth of the church, and have made its good of no account, and therefore have also adulterated and perverted everything that is said in the Word about good, that is, about charity toward the neighbor and about love to God.

[3] As regards the “glorification in Pharaoh and in his army,” this here denotes immersion in this hell and being encompassed by waters as of a sea at the mere presence of the Lord, as was said above. For the evil flee from the presence of the Lord, that is, the presence of the good and truth that are from Him, feeling horror and torment at their mere approach; and also by reason of this presence they become encompassed about with their own evils and falsities, for these then burst forth from them; and indeed these evils and falsities encompass and are interposed in order to prevent the Divine from flowing in and tormenting them. This is the Divine effect which is here signified by the “glorification in Pharaoh and in his army.” That this effect is from the Divine Human of the Lord, is because, as before said, by the Lord’s coming into the world and assuming the Human and making it Divine, He cast all falsities and evils into hell, and reduced truths and goods in the heavens into order, and liberated from damnation those who were of the spiritual church.
