3167. 'And to [her] mother' means to natural truth also, that is to say, spiritual things passed from the rational to it, even as they passed to natural good, dealt with just above. This is clear from the meaning of 'a mother' as the Church, which by virtue of truth is called 'a mother', dealt with in 289, 2717. So that people may know how spiritual things pass to natural good and to natural truth as a result of truth being introduced into good in the rational, a brief description must be given here. Everyone has an internal and an external, his internal being called the internal man, and his external the external man. But few know what the internal man is and what the external. The internal man is one and the same as the spiritual man, and the external man one and the same as the natural man. The spiritual man depends for understanding and wisdom on things that belong to the light of heaven, whereas the natural depends for its understanding and wisdom on things that belong to the light of the world. Regarding those two kinds of light, see 3138. For in heaven none but spiritual things exist, whereas in the world none but natural exist. The human being was created in such a way that in him spiritual things and natural things, that is, his spiritual man and his natural man, should accord with each other or make one. But in that case the spiritual man ought to have control over the things in the natural, and the natural man ought to obey, like a servant his master.

[2] Through the Fall however the natural man started to raise itself above the spiritual man and so turn Divine order itself upside down. As a consequence the natural man separated itself from the spiritual, and spiritual things could not reach it any longer except so to speak through chinks to provide the ability to think and speak. But so that spiritual things might flow in once more into the natural man this had to be regenerated by the Lord, that is, truth from the natural man had to be introduced and joined to good in the rational. When this happens spiritual things have access to the natural man, for now the light of heaven flows in and illuminates things in the natural man, and causes what is there to receive light. The goods there receive the warmth that the light conveys, which is love and charity, whereas the truth receives rays of light, which is faith. It is in this way that spiritual things pass from the rational into natural good and truth. Natural good in that case consists in all the delight and satisfaction gained from having service to the spiritual man as the end in view, and so service to the neighbour, more so to one's country, more so still to the Lord's kingdom, and above all to the Lord. And natural truth consists in all doctrinal teaching and factual knowledge which have wisdom, that is, the performance of those things, as the end in view.

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.
