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.

3399. The expression 'lying with a wife' means in the internal sense perverting and adulterating truth, here truth that is Divine, because 'a wife' - Rebekah - represents Divine Truth, as shown above. This may be seen from the consideration that instances of lying together, adultery, and prostitution in the Word do not mean anything other than perversions of good and falsifications of truth, as shown in 2466, 2729. The reason why they do so is that all adultery is absolutely contrary to conjugial love, so much so that it is destructive of it; and conjugial love originates in the marriage of good and truth, 2508, 2618, 2727-2759, 3132. Consequently things that are contrary to good and truth, or that destroy them, are in the Word called forms of adultery.

[2] But it should be realized that those who belong to the spiritual Church are not able to adulterate good to such an extent that they profane it, for the reason that they are not able to receive good so far as to perceive it, as those who are celestial do. They are able however to profane truth because they are able to acknowledge it. Yet in the final period of the Church they are not able even to acknowledge truth, because at that time universal disbelief prevails concerning the Lord, concerning life after death, and concerning the internal man. And the disbelief which reigns universally makes it impossible for them to penetrate into the interior truths of faith. That which prevails with everyone universally limits them and keeps them back from entering more deeply into such things, even when the person is unaware of that universal disbelief and also when he supposes that he does believe.

[3] But those who are able to profane good are such as belong to the celestial Church, for they are able to receive it so as to perceive it, as was done by those living before the Flood who have consequently been segregated from everyone else and are kept in a hell separated from the hells of others - regarding which see 1265-1272. The prevention of the occurrence ever again of the profanation of good is meant by the reference to Jehovah expelling man and causing cherubim to dwell away from the east towards the garden of Eden, and the flame of a sword turning this way and that to guard the way of the tree of life, Genesis 3:24. On these matters, see 308, 310.
