3493. And his eyes were dim that he could not see. That this signifies when the rational desired to enlighten the natural with the Divine, is evident from the signification of “eyes,” as being the interior or rational sight (see n. 2701); and from the signification of “seeing,” as being to perceive and understand (n. 2150, 2325, 2807); hence when the eyes are said to be dim,” it signifies that there is no longer any perception, here, no perception of those things which are in the natural; and this being the signification of these words, it is signified that the rational desired to enlighten the natural with the Divine. How the case herein is may be seen from what has been said and shown before concerning the rational and natural in man when he is being regenerated, namely, that the rational is regenerated before the natural, for the reason that the rational is more interior and thus nearer to the Divine; and also because it is purer, and thus fitter to receive the Divine than is the natural; and further because the natural is to be regenerated through the rational, as may be seen above (n. 3286, 3288, 3321).

[2] When therefore the rational has been regenerated and not the natural, the former appears to itself to be dim-sighted, because there is not correspondence; for the rational has its sight from the light of heaven, and the natural has its sight from the light of the world; and unless there is correspondence, the rational can see nothing which is in the natural, all therein being to it as shade, or even as thick darkness. But when there is correspondence, then the things in the natural appear to the rational in light, because the things which are of the light of the world are then enlightened by those which are of the light of heaven, and thereupon become as it were translucent. But these things appear better from what has been before said and shown concerning correspondence (n. 2987, 2989, 2991, 2996, 3002, 3138, 3167, 3222, 3223, 3225, 3337, 3485). Hence it may in some sort be apprehended that by the words, “the eyes of Isaac were dim that he could not see,” is signified that the rational desired to enlighten the natural with the Divine, that is, to make it also Divine, for in the supreme sense the Lord is treated of; which may consequently be illustrated by what takes place with man when being regenerated, as before mentioned, for the regeneration of man is an image of the Lord’s glorification (n. 3043, 3138, 3212, 3296, 3490).

2996. In this world it is a great secret, although in the other life nothing is better known to every spirit, that all things in the human body have a correspondence to those in heaven; insomuch that there is not the smallest particle in the body, to which something spiritual and celestial does not correspond; or what is the same, to which heavenly societies do not correspond, for these exist according to all the genera and species of spiritual and celestial things; and this in such an order that together they represent one man, even as to all his parts, in general and in particular, both the interior and the exterior. Hence it is that the universal heaven is also called the Grand Man; and hence it is that it has been so often said that one society belongs to one province of the body, another to another, and so on. The reason is that the Lord is the Only Man, and heaven represents Him; and the Divine good and truth that are from Him are what make heaven; and because the angels are therein, they are said to be in the Lord. But they who are in hell are outside this Grand Man, and correspond to things unclean, and also to bodily corruptions.
