6380. 'And his teeth white from milk' means that the Divine Natural is nothing else than the good of truth. This is clear from the meaning of 'white' as that which is used with reference to truth, dealt with in 3301, 3993, 4007, 5319; from the meaning of 'teeth' in the genuine sense as the natural, for the hard parts of a person's body, such as his teeth, bones, and cartilages, correspond to the truths and forms of good that belong to the lowest parts of the natural; and from the meaning of 'milk' as the celestial-spiritual, or what amounts to the same, the good of truth, dealt with in 2184. The Lord's Divine Natural is said to be the good of truth when it is considered in relation to people who believe in and love the Lord; for members of the external Church are unable to go any higher in their thinking than the Lord's Divine Natural, whereas the thinking of members of the internal Church goes above the natural to the Internal. For the idea of the Lord formed by anyone who believes in Him is conditioned by how far he can rise in his thinking. Those who are aware of what the internal is can have an idea of the internal; but those who are not aware of what the internal is have an idea of the external. This is why the Lord's Divine Natural is said to be the good of truth, when in fact His entire Human is the Divine Good of Divine Love.

4526. To take further the correspondence of the sight of the eye, begun at the end of the previous chapter, it should be recognized that its correspondence is with the things of the understanding, for the understanding is internal sight and this internal sight functions in the light which is above the light of the world. The reason why man is able to acquire intelligence to himself by means of the things which are seen by him in the light of the world is that a higher light, or the light of heaven, flows into the objects made visible by the light of the world and causes them to be seen in a representative and correspondential fashion. For the light that is above the light of the world is that which proceeds from the Lord who enlightens the whole of heaven. Intelligence and wisdom themselves which come from the Lord are seen there as light, and it is this light which constitutes man's understanding or internal sight. When that light is flowing in through the understanding into the objects made visible by the light of the world it causes them to be seen in a representative and correspondential fashion, and so to be seen with understanding. And because the sight of the eye which operates in the natural world corresponds to the sight of the understanding which operates in the spiritual world, it corresponds to the truths of faith, for these belong to a genuine understanding. Indeed truths constitute the whole understanding of man, for every part of his thought revolves around the matter of whether something is so or not so, that is, whether it is true or not true. As regards the sight of the eye corresponding to the truths and goods of faith, see above in 4410.
