2524. 'She herself also said, He is my brother' means that the rational itself so declared that celestial good should be coupled with it. This becomes clear from the meaning of 'a sister', to whom 'she herself' refers here, as the rational, 1495, 2508, and from the meaning of 'a brother' as good that stands related to truth, 367, 2508. For the implications of this are as follows: Divine Good and Divine Truth are united to each other as if in a marriage. From this comes the heavenly marriage, and also conjugial love, even down to the natural world below. But the good and truth of the rational are not joined to each other as if in a marriage but as in a blood relationship like that of brother and sister. For as regards truth, the rational is conceived from an influx of Divine Good into the affection for knowledge and cognitions, see 1895, 1902, 1910, whereas the good of the rational comes through an influx of Divine Good into that truth, which then becomes that good itself which belongs to charity and is 'the brother' of faith, or what amounts to the same, of truth, 367.

[2] As regards the way in which the good and truth of the rational are acquired, its good comes from Divine good, but not its truth from Divine truth, for the truth of the rational is acquired through knowledge and cognitions which are implanted by means of the senses, external and internal, and so by an external route. Consequently many illusions that result from sensory impressions cling to the truths of that rational which cause those truths not to be truths. Nevertheless when Divine Good flows into them and takes hold of them they are in that case seen as truths and are acknowledged as truths, even though they are no more than appearances of truth. The good itself within those truths undergoes modification determined by the shadows there and comes to have the same nature as the truth. This is one arcanum which lies concealed in these words, that the rational so declared that celestial good should be coupled with it.

1895. 'She had an Egyptian servant-girl' means the affection for knowledge. This is clear from the meaning of 'a servant-girl' and from the meaning of 'Egypt'. Sarai, who is the mistress or lady, represents and means truth allied to good, as stated already. Truth allied to good is in the genuine sense intellectual truth, but rational truth comes below this and so is inferior. The latter is born from knowledge and cognitions that have been made living by means of an affection corresponding to them. Because this affection is part of the exterior man, it ought to be subservient to intellectual truth, which resides inmostly, in the way that a servant-girl is subservient to her mistress or a maid to the lady of - the house. That affection therefore is what is represented and meant by 'the servant-girl Hagar'.

[2] No one can have much understanding of anything said about these matters until he knows what intellectual truth is in the genuine sense and also in what way the rational is born, namely from the internal man as the father, and from the exterior or natural man as the mother. Unless the two are joined together nothing rational ever comes into being. The rational is not born from knowledge and cognitions, as people suppose, but from the affection for them, as becomes clear merely from the fact that nobody can possibly become rational unless some delight in or affection for such knowledge and cognitions burns within him. The affection constitutes the maternal life itself, while the celestial and spiritual within that affection constitute the paternal life. Consequently it is the degree and the quality of a person's affection that determine the degree and the quality of the rationality that is developed in him. In themselves facts and cognitions are nothing other than things that are dead, or instrumental causes, which are made alive by the life that belongs to affection. This is how everyone's rational man is conceived. The reason why the servant-girl was Egyptian and why that fact is mentioned is that 'Egypt' means knowledge, as has been shown already in 1164, 1165, 1186, 1462,
