474. And he said to me, These are they who come out of great tribulation.- That this signifies information that they are those who have been in temptations, is evident from the signification of, "he said to me," as denoting information; and from the signification of tribulation, or great affliction, as denoting temptations, of which we shall speak presently. Something shall first be said here concerning the temptations which those undergo in the spiritual world who are in falsities from ignorance, and who are here treated of. Only those undergo temptations there who have lived a good life in the world according to their religion, wherein were falsities of doctrine in which they believed. For by temptations falsities are shaken off, truths are implanted, and thus they are prepared for heaven; for all those who shall come into heaven must be in truths; wherefore so long as they are in falsities they cannot come into heaven. The reason is, that the Divine Truth proceeding from the Lord makes heaven, and makes the life of the angels there, therefore falsities, because they are opposed to truths, and because opposites destroy, must first be removed, and they cannot be removed except by temptations.

[2] That temptations perform this use, may be seen in the Doctrine of the New Jerusalem, (n. 187-201), where temptations are treated of. The reason why they are let into temptations in the spiritual world after the life in the body, is, that they could not be tempted in the world on account of the falsities of religion in which they were, and which were everywhere dominant. It must be understood, that all those who are let into temptations are saved; but the evil, who are in falsities from evil, are not tempted, for with them truths cannot be implanted, because the evils of their lives offer a hindrance; but truths are taken away from them, and therefore they remain in pure falsities, and are then immersed deeply in hell, according to the quality of evil from which such falsity springs. In a word, those who are about to come into heaven are vastated in regard to their falsities, and those who are about to go into hell are vastated in regard to truths; that is, falsities are removed from those who are about to go to heaven, and truths are taken away from those who are about to go to hell. For no one can enter heaven with falsities, nor hell with truths, because truths from good make heaven, and falsities from evil make hell. The temptations of those whose falsities have to be removed are treated of in many passages in the Word, and especially in David, and are called afflictions, tribulations, and vastations; but there is no need to quote those passages here, since it can be seen without them that tribulations and afflictions, when spoken of in reference to good, mean, in the spiritual sense, temptations.

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.
