3819. 'The name of the elder was Leah' means the nature of the affection for external truth; 'and the name of the younger Rachel' means the nature of the affection for internal truth. This is clear from the representation of 'Leah' as the affection for external truth, and of 'Rachel' as the affection for internal truth, both dealt with in 3793; and from the meaning of 'the name' as the nature of, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006. Leah is called 'the elder' because external truth is learned first, and Rachel 'the younger' because internal truth is learned from then on after that; or what amounts to the same, a person first of all feels an affection for external truths, and from then on after that an affection for internal truths. external truths provide the basic outline for internal truths, for they are the general outlines into which particular details are added. Unless a person has a general outline of the idea of a thing he does not make sense of any particular aspect of it. This explains why the literal sense of the Word contains general truths but the internal sense particular truths. General truths are called external, but particular truths internal. And because truths devoid of affection are not truths because there is no life to them, the affections for them are therefore meant when external and internal truths are referred to.

1394. The perception which angels and spirits have is such that any one of them can know in an instant the nature of the love and faith in another Hence it is that according to their similarity with one another they are joined together into communities, and according to their dissimilarity they are withheld from such associations. And this is so completely the case that not even the smallest difference fails to draw them together or to set them apart. Consequently the communities in heaven are so distinct and separate from one another that it is impossible to envisage anything more distinct, such distinctness being determined by all the differences of love to and faith in the Lord, which are countless. This is how the heavenly form is produced, the nature of which is such that it presents itself as one human being. And this form is constantly being perfected.
