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.

3212. 'And Isaac was comforted after [the death of] his mother' means a new state. This becomes clear from the meaning of 'receiving comfort' as a new state, for a state of comfort is a new state, which, following the previous one, is meant by 'after his mother'. The new state is a state of glorification of the Rational; already so as to good, it now became glorified as to truth. The Rational was glorified when it became Divine as regards both good and truth.

[2] As to the Human the Lord was made new, that is, was glorified, or what amounts to the same, was made Divine; but nobody can possibly grasp this, nor thus believe it, who is immersed in worldly and bodily loves. He has no knowledge at all of what spiritual or celestial is, and does not even wish to know. But anyone who is not immersed in worldly and bodily loves can perceive it, for he believes that the Lord is one with the Father, that everything holy comes from Him, and consequently that He is Divine even as regards the Human. And anyone who believes this perceives it in his own way.

[3] The state of the Lord's glorification can be grasped to some extent from the state of man's regeneration, for man's regeneration is an image of the Lord's glorification, 3043, 3138. When a person is being regenerated he becomes completely different from before and is made new. Once he has been regenerated therefore he is called one who has been born again and created anew. At that point a person's face and speech remain the same, but not so his mind. Once he is regenerate his mind is open towards heaven, and love to the Lord and charity towards the neighbour, together with faith, reside in it. It is the mind that makes him a person who is different and new. Change of state cannot be discerned in a person's body, only in his spirit. The body is merely the covering for his spirit. When he lays aside the former his spirit is seen, and indeed in a form altogether different if he has been regenerated. In this case it is a visible form of love and charity that possesses beauty beyond description, 553, replacing the previous form, which had been a visible form of hatred and cruelty possessing ugliness also beyond description. From this it may become clear what a regenerate person is, that is, one born again or created anew, namely one who is altogether different from before and who is new.

[4] From this image one can have some conception of the Lord's glorification. He was not regenerated as man is but was made Divine, being made so from Divine love itself, for He was made Divine love itself. The nature of His form at that time was shown to Peter, James, and John when they were allowed to see Him not with their physical eyes but with those of the spirit, that is to say, on the occasion when His face shone like the sun, Matthew 17:2. This was His Divine Human, as is clear from the voice which at that time declared from the cloud, 'This is My beloved Son', Matthew 17:5 - 'the Son' being the Divine Human, see 2628.
