3498. 'I do not know the day of my death' means the life within the natural. This is clear from the meaning of 'day' as state, dealt with in 23, 487, 488, 493, 893, 2788, and from the meaning of 'death' as rising again or awakening into life, dealt with in 3326. 'The day of death' accordingly means a state of awakening to life, or what amounts to the same, it means life - the life within the natural, it is evident, being meant in particular here, because that life is the subject here. What is implied in all this does not become clear unless one knows about the life of the rational, and the life of the natural, or what amounts to the same, about the life of the internal man and the life of the external man. The life of the rational or internal man is distinct and separate from that of the natural or external man, so distinct indeed that the life of the rational or internal man may exist quite independently of the life of the natural or external man; but the life of the natural or external man cannot exist apart from that of the rational or internal man. For the external man lives from the internal man, so much so that if the life of the internal man ceased to be, the life of the external man would instantly be no more. Exterior things are accordingly dependent on interior in the way that things which are posterior exist from those that are prior, or as an effect exists from its efficient cause. For if the efficient cause ceased to be, the effect would instantly be no more. The same is also so with the life of the external man in relation to the life of the internal man.

[2] This may be seen even more clearly in the human being, for while a person is in the world, that is, while he lives in the body, his rational is distinct and separate from the natural, so much so that he can be raised above the level of external sensory perceptions which belong to the body, and even to a certain extent above the level of inner sensory perceptions which belong to his natural man, and to be aware on the level of his rational, and so of spiritual thought. This is even more evident from the fact that when a person dies he leaves behind him altogether the external sensory perceptions that belong to the body, retaining at the same time the life of his interior man. Indeed he brings with him even the facts that exist in the external or natural memory, though he does not have the use of them, see 2475-2477, 2479-2483, 2485, 2486. From this it is evident that the rational or internal man is distinct and separate from the external man. But while a person is living in the body his rational does not seem to be distinct and separate from the natural, the reason being that he is living in the world or the natural order. That being so the life of the rational manifests itself within the natural, so much so that the rational does not seem to have any life at all if the natural does not at the same time have any. The amount of life that the rational seems to have in this case depends on how far the natural corresponds to it - see above in 3493. From this it may be seen that there is a corresponding life in the natural, which life is meant by the words which Isaac addressed to Esau, 'I do not know the day of my death'. For 'Isaac' represents the rational, and 'Esau' the natural, in both cases as regards good.

3286. 'On behalf of his wife because she was barren' means that the Divine Natural did not as yet exist. This is clear from the meaning of 'a wife' as Divine Truth joined to the Divine Good of the Rational, which Truth, as shown in the previous chapter, is represented by 'Rebekah'; and from the meaning of 'barren' as the non-existence as yet of the Divine Natural. For the truth of the matter is that the Divine Natural came into being from the Divine Good of the Rational as the father and from Divine Truth there as the mother. While the Divine Natural does not as yet exist the Truth of the Rational is called 'barren', here 'a barren wife'.

[2] In man's case the situation is that while he is being regenerated the Lord instills good, that is, goodwill to the neighbour, into his rational. This goodwill or good has truth from the natural man allied to it. Once this is completed his natural has still to be regenerated, as anyone may recognize from the fact that the internal or rational man often conflicts with the external or natural; and as long as conflict exists the natural is not regenerate. And while the natural remains unregenerate the rational as regards truth is barren. As is the case in general so it is similarly in every particular instance in which the rational does not agree with the natural; in every such instance the rational as regards truth is called barren.

[3] The work of regeneration revolves for the most part around making the natural man correspond to the rational man, not only in general but also in particular. And the natural man is brought into such correspondence by the Lord by means of the rational. That is to say, good is instilled into the rational, and within this good as the soil truths are planted, after which by means of rational truths the natural is brought into obedience. When it is obedient it in that case corresponds; and to the extent it corresponds a person has been regenerated.
