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.

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.
