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.

3043. 'You are clear from my oath' means the freedom that the natural man has. This is clear from the meaning of 'the servant', to whom Abraham's words are addressed, as the natural man, 3019, and from the meaning of 'being clear if the woman is unwilling to follow' in the proximate sense as not being bound if the affection for truth were not separated. These words, it is evident, imply the freedom that the natural man has; for the affection for truth, which is the subject here, and also its separation, is in the internal sense attributed to the natural man. In the historical sense these words do indeed have other connotations, but in the internal sense their implications are such.

[2] Regarding human freedom, see what has been stated and shown already in 892, 905, 1937, 1947, 2744, 2870-2893, for these paragraphs show what is implied by freedom. Freedom is attributed to the natural man, but not so much to the rational man, because it is by way of the rational man and into the natural man that good flows in, in heavenly freedom, from the Lord. It is the natural man that is the recipient of that good, and in order that it may receive it and so be joined to the heavenly freedom flowing in by way of the rational man, the natural man is left in freedom. For freedom goes with love or affection. If the natural man does not receive an affection for truth from an inflowing affection for good, that man is in no sense joined to the rational. This is how it is with man, whom the Lord reforms by means of freedom, see 1937, 1947, 2876-2878, 2881.

[3] In the Lord's case He too left the Natural in freedom when He made His Rational Divine as regards truth, that is, when He allied Divine Truth to the Divine Good of the Rational, for He was willing to make His Human Divine in the ordinary way. The ordinary way is that which occurs in anyone who is being reformed and regenerated. The actual reformation and regeneration of man is therefore a replica of what took place in the Lord. For by reformation and regeneration he becomes a new person, and is consequently called one begotten anew, and one created anew; and to the extent that he has been reformed he seems to have the Divine within him. But there is this difference, that the Lord made Himself Divine by His own power, whereas man is not able to effect the slightest reformation by his own power, only from the Lord. The expression 'seems to have the Divine' is used because man is solely a recipient of life, whereas the Lord is Life itself as to both Essences, see 1954, 2021, 2658, 2706, 3001.
