3721. 'And this is the gate of heavens means that which serves as the ultimate degree of order, through which there is, so to speak, a way in from the natural creation. This is clear from the meaning of 'the gate' as that through which exit or entrance is made. The reason why here that which serves as the ultimate degree of order is meant is that the subject is the natural, which 'Jacob' represents. What 'a gate' means is clear from what has been stated and shown in 2851, 3187, and the fact that the natural is the ultimate degree of order from what has been introduced in 775, 2181, 2987-3002, 3020, 3147, 3167, 3483, 3489, 3513, 3570, 3576, 3671. The reason why through that ultimate degree there is so to speak a way in from the natural creation is that man's natural mind is the place through which things of heaven, that is, which are the Lord's, flow in and come down into the natural creation; and through that same mind the things that belong to the natural creation go back up, see 3702. The fact that there is so to speak an entrance from the natural creation through the natural mind into interior parts may be seen from what has been stated and shown in various places before.

[2] It seems to man as though worldly objects enter in through his physical or external senses and affect interior things, and so that there is an entrance from the ultimate degree of order into things that are within. But this is an appearance and illusion, as is evident from the general rule that what is secondary cannot flow into what is primary, or what amounts to the same, what is lower cannot flow into what is higher, or what is also the same, what is exterior into what is interior, or what is still the same, things of the world and the natural creation into those of heaven and of the spirit. For the former are grosser, the latter purer, and the grosser things that belong to the external or natural man come into being and are kept in being from those belonging to the internal or rational man. Those grosser things are unable to have any effect on the purer things but are affected by them. The nature of this influx however, seeing that appearance and illusion itself convince people that the reverse is true, will in the Lord's Divine mercy be discussed separately, where influx is the subject. This then is why it is said that through the ultimate degree of order there is, so to speak, a way in from the natural creation.

3138. These three verses deal with the preparation and enlightenment of the natural man so that the truth which was to be joined to good in the Rational might be summoned from there. With regard to that preparation and enlightenment the position is that there are two kinds of light which shape man's intellectual concepts - the light of heaven, and the light of the world. The light of heaven comes from the Lord who to angels in the next life is the Sun and Moon, see 1053, 1521, 1529, 1530. The light of the world comes from the sun and moon which a person sees with his physical eyes. The internal man receives his sight and understanding from the light of heaven whereas the external man receives his sight and understanding from the light of the world. The influx of the light of heaven into ideas formed in the light of the world produces enlightenment and at the same time recognition - the recognition of truth if a correspondence exists, the recognition of falsity instead of truth if that correspondence does not exist. But enlightenment and recognition are not possible unless affection or love is present, which is spiritual warmth and imparts life to the things illumined by the light. This may be compared to the light of the sun. It is not the light of the sun but the warmth within the light that imparts life to plants, as is evident from the seasons of the year.

[2] The verses which follow immediately after this describe the preparation further - the light of heaven, which is the Lord's Divine light, flowed into the ideas formed in the light of the world in His natural man so that He might bring forth from there the truth that was to be joined to good in the Rational. Thus it was to be brought forth in what is the ordinary way. Therefore to make His Human Divine the Lord came into the world in the ordinary way, that is, He was willing to be born as any other person is born, to receive instruction as any other does, and to be born again as any other, but with this difference: Man is born again from the Lord, whereas the Lord not only regenerated Himself from Himself, but also glorified Himself, that is, made Himself Divine; also man is made new through the influx of charity and faith, whereas the Lord was made so through the influx of Divine Love that was within Him and that was His own. From this it may be seen that man's regeneration is an image of the Lord's glorification, or what amounts to the same, that in the process of man's regeneration as the image one can envisage, though remotely, the process of the Lord's glorification.
