3493. 'And his eyes were becoming dark so that he could not see' means when the Rational wished to enlighten the Natural from the Divine. This is clear from the meaning of 'the eyes' as interior or rational sight, dealt with in 2701, and from the meaning of 'seeing' as recognizing and understanding, dealt with in 2150, 2325, 2807. Consequently when 'the eyes' are said 'to be becoming dark' the meaning is that no discernment exists any longer, in this case no discernment of the things present in the natural. This being the meaning of these words, the fact that the Rational wished to enlighten the Natural from the Divine is meant. What this implies may be seen from the following things stated and shown already about the rational and the natural with man when he is being regenerated: The rational is regenerated before the natural, for the reason that the rational is interior and so closer to the Divine, and also is purer and so more suited to receiving the Divine than the natural is; and for the further reason that the natural has to be regenerated by way of the rational, see 3286, 3288, 3321.

[2] When therefore the rational has been regenerated but not the natural the former in that case seems to itself to be made dark, for no correspondence exists between the two. Actually the rational receives its sight from the light of heaven, whereas the natural receives its sight from the light of the world; but unless a correspondence exists between the two the rational is unable to see anything that is in the natural. Everything there is like shadow or even like thick darkness. But once a correspondence does exist, things that are in light in the natural are then apparent to the rational, for things that belong to the light of the world are then enlightened by those that belong to the light of heaven, which are so to speak shining through. But these matters are more clearly evident from what has been stated and shown already about correspondence see 2987, 2989-2991, 3002, 3138, 3167, 3222, 3223, 3225, 3337, 3485. Through what is stated and shown in these paragraphs one may grasp to some extent that the words 'Isaac's eyes were becoming dark so that he could not see' mean that the Rational wished to enlighten the Natural from the Divine, that is to say, to make even the Natural Divine, for the subject in the highest sense is the Lord. Light is thereby shed on this matter by what occurs with man when he is being regenerated and which has been described already; for man's regeneration is an image of the Lord's glorification, 3043, 3138, 3212, 3296, 3490.

3321. 'For I am weary' means a state of conflict. This is clear from the meaning of 'weary' or weariness as a state of conflict, dealt with above in 3318. A second reference occurs here to his being weary so as to confirm the point that the joining together of good and truth within the natural is effected by means of spiritual conflicts, that is, by means of temptations. With regard to the joining together of good and truth in the natural, the position in general is that man's rational receives truths before his natural receives them, the reason being that the Lord's life which, as has been stated, is the life of His love, may be able to flow in by way of the rational into the natural, bring order into it, and make it submissive. For the rational is purer, and the natural grosser, or what amounts to the same, the former is interior, the latter exterior. It is according to order - an order that one can know - that the rational is able to flow into the natural, but not the natural into the rational.

[2] Consequently a person's rational is able to be adjusted to truths and to receive them before the natural does. This becomes quite clear from the fact that the rational man with someone who is to be regenerated conflicts greatly with the natural, or what amounts to the same, the internal man does so with the external. For as is also well known, the internal man is able to see truths and also to will them, but the external man refuses to see them and stands opposed to them. For in the natural man there are facts, which are to a great extent derived from the illusions of the senses, and which, although they are falsities, he nevertheless believes to be truths. There are also countless things which the natural man does not grasp, since the natural man, compared with the rational man, is in shade and thick darkness; and the things which the natural man does not grasp are thought not to exist or not to be so. There are also desires in the natural man which are those of self-love and love of the world, and the things which support those desires he calls truths. And when a person gives in to them everything that arises from them is contrary to spiritual truths. Present also are reasonings derived from falsities imprinted since early childhood. What is more, a person comprehends plainly with his senses the things which exist in his natural man, but less so those which exist in his rational until he has shed the body. This also causes him to suppose that the natural constitutes the whole, and what does not fall within the compass of his natural senses he believes to be scarcely anything.

[3] These and many others are the factors which cause the natural man to receive truths much later and with greater difficulty than the rational man receives them. Consequently conflict occurs, which persists for rather a long time and does not end until the recipient vessels of good in the natural man have been softened by means of temptations, as shown above in 3318; for truths are nothing else than recipient vessels of good, 1496, 1832, 1900, 2063, 2261, 2269. The harder those vessels are the more firmly is a person settled in the things referred to above. And the more firmly settled he is, the more serious is the conflict if he is to be regenerated. This therefore being the situation with the natural man - that the joining of truths to good in the natural man is effected by means of the conflicts brought about by temptations - Esau's statement 'I am weary' occurs a second time here.
