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.

3671. 'You and your seed with you' means to the good and the truth born from this good. This is clear from the representation of Jacob, to whom 'you' refers here, as the good of truth, or good that is a product of truth, dealt with above, and from the meaning of 'seed' as the good and truth of faith, dealt with in 1025, 1447, 1610, 2848, 3373. 'With you' means that it was allied to the good of truth, represented by 'Jacob'. Good and truth are like seeds and the soil. Interior good is like seed that is productive, though not unless it is sown in good soil. Exterior good and truth are like the soil in which it is made productive. The former, that is to say, the seed, which is interior good and truth, cannot otherwise take root. This is why a person's rational is regenerated first of all, for the rational is where the seeds are; then after that the natural is regenerated to serve as the soil for them, 3286, 3288, 3321, 3368, 3493, 3576, 3620, 3623. And because the natural is like the soil, good and truth can be made fruitful and be multiplied within the rational, which could not take place if the soil where the seed has its root were anywhere else. From this comparison one may see as in a mirror what regeneration is like and the numerous arcana that go with it.

[2] Understanding good and truth and willing them is the function of the rational, and perceptions of good and truth resulting from this are like seeds; but knowing them and doing them is the function of the natural. Facts and deeds are like the soil. When a person has an affection for the facts that corroborate what is good and true, the more so when he experiences joy in acting them out, those facts are seeds that are present and growing in the natural as their own proper soil; and there they grow. As a consequence good is made fruitful and truth is multiplied, and they are constantly springing up out of that soil into the rational and perfecting it. The situation is different when a person understands what is good and true, and also interiorly perceives that he wills something, and yet does not desire to know these things, let alone do them. In that case good cannot be made fruitful nor truth be multiplied within the rational.
