6240. 'Will be yours' means that they will be in the rational which is within the internal. This is clear from the consideration that the internal celestial represented by 'Joseph' exists in the rational, 4286, 4963, and therefore 'will be yours' means that they will be in the rational, just as previously 'they are mine' meant within the natural, in which the truth of the natural represented by 'Jacob' exists, 6236.

Let a brief statement be made about what the rational is. The area of understanding within the internal man is called the rational, while the area of understanding in the external man is called the natural, so that the rational is internal and the natural is external; and the two are completely distinct and separate from each other. A truly rational person is none other than one who is called a celestial person; that person enjoys a perception of what is good, and from that good a perception of what is true. But a person who does not have such perception but merely an awareness that a thing is true, because he has been taught that it is, and has a conscience as a result of that awareness, is not truly a rational person but an interiorly natural one. He is what those who belong to the Lord's spiritual Church are like. These two kinds of people are as different from each other as the light of the moon is from the light of the sun; and that also is why the Lord is seen by spiritual angels as the moon but by celestial ones as the sun, 1521, 1529-1531, 4060, 4696. Very many in the world imagine that a rational person is one who can reason with skill on many subjects and link one piece of reasoning to another in such a way that the conclusion he draws seems to be the truth. But that ability occurs even in very wicked people who are expert reasoners and can make the deduction that evil things are good and false ideas are true, or that good things are evil and true ideas are false. But anyone who stops to reflect can see that this is wicked imagination and not rationality. Rationality consists in seeing inwardly and perceiving that what is good is indeed good, and from this that what is true is indeed true; for such vision and perception of these things comes from heaven. The reason why those who belong to the Lord's spiritual Church are interiorly natural people is that they acknowledge as true only what they have learned from parents and teachers and later on firmly established for themselves. There is nothing else from which they can see inwardly or perceive whether a thing is true except what they have thus firmly established for themselves - unlike those who are celestial; which is why the latter are rational people, whereas the former are interior natural ones. The internal celestial, which 'Joseph' represents, exists in the rational, but spiritual good, which 'Israel' represents, exists in the interior natural, 4286; for they are spiritual people who are represented by' Israel', and celestial ones who are represented by 'Joseph'.

4963. 'And Joseph' means the celestial of the spiritual from the rational. This is clear from the representation of 'Joseph' as the celestial-spiritual man that comes from the rational, dealt with in 4286. Here therefore, since the Lord is the subject, the Lord's Internal Man is represented by him. Everyone born a human being is external and internal. His external man is that which is seen with the eyes; it is that which enables him to live in association with other people and enables him to carry out what belongs properly to the natural world. But the internal man is one that is not seen with the eyes; it is what enables a person to live in association with spirits and angels and to carry through what belongs properly to the spiritual world. Everyone has an internal and an external, that is, the internal man and the external man exist, to the end that through man heaven may be joined to the world. For heaven flows by way of the internal man into the external and from that influx gains a perception of what exists in the world, while the external man in the world gains from the same influx a perception of what exists in heaven. It is to this end that the human being has been created the way he has.

[2] The Lord's Human too had an External and an Internal because it pleased Him to be born like any other human being. The External, or His External Man, has been represented by 'Jacob' and after that by 'Israel', but His Internal Man is represented by 'Joseph'. The latter - the Internal Man - is what is called the celestial-spiritual man from the rational; or what amounts to the same, the Lord's Internal, which was the Human, was the celestial of the spiritual from the rational. This, and the glorification of it, are dealt with in the internal sense of the present chapter and those that follow it in which Joseph is the subject. What the celestial of the spiritual from the rational is has been explained already in 4286, 4585, 4592, 4594, namely that which comes above the celestial of the spiritual from the natural, represented by 'Israel'.

[3] The Lord was indeed born like any other human being. But it is well known that everyone who is born depends for his make-up on both his father and his mother; also that he derives his inmost self from his father, but his more external aspects, or those which clothe his inmost self, from his mother. That is to say, both what he derives from his father and what he derives from his mother are defiled with hereditary evil. But in the Lord's case it was different. That which He derived from His mother possessed a hereditary nature essentially the same as that existing in any other human being; but what He derived from His Father, who was Jehovah, was Divine. Consequently the Lord's Internal Man was unlike the internal of any other human being, for His Inmost Self was Jehovah. Being intermediate this is therefore called the celestial of the spiritual from the rational. But in the Lord's Divine mercy more will be said about this later on.
