205. There is an affiliation of all in heaven in accordance with spiritual relationships, that is, relationships of good and truth in their order. It is so in the whole heaven; so in each society, and so in each house. Because of this angels who are in like good and truth recognize each other, as relatives by blood and marriage do on the earth, precisely as if they had been acquainted from infancy. The good and truth in each angel, which constitute his wisdom and intelligence, are affiliated in like manner; they recognize each other in like manner, and as they recognize each other they join themselves together;{1} and in consequence those in whom truths and goods are thus joined in accordance with a form of heaven see things following one another in series, and how they cohere widely round about; but those in whom goods and truths are not conjoined in accordance with the form of heaven do not see this. {Footnote 1} Good recognizes its truth, and truth its good (n. 2429, 3101, 3102, 3161, 3179, 3180, 4358, 5704, 5835, 9637). In this way good and truth are conjoined (n. 3834, 4096, 4097, 4301, 4345, 4353, 4364, 4368, 5365, 7623-7627, 7752-7762, 8530, 9258, 10555). This is effected by influx from heaven (n. 9079). 206. In each heaven there is such a form, and in accordance with it the angels have communication and extension of thoughts and affections, and thus in accordance with it they have intelligence and wisdom. But the communication of one heaven with another is different, that is, of the third or inmost with the second or middle, and of this with the first or outmost. But the communication between the heavens should not be called communication but influx. About this something shall now be said. That there are three heavens distinct from each other can be seen above in its own chapter (n. 29-40). 207. That between one heaven and another there is influx but not communication can be seen from their relative position. The third or inmost heaven is above, the second or middle heaven is below, and the first or outmost heaven is still lower. There is a like arrangement in all the societies in each heaven, for example, some dwell on elevated places that appear like mountains (n. 188); on the top of which those of the inmost heaven dwell; below these are the societies of the second heaven, below these again the societies of the outmost heaven. The same is true every where, both in elevated places and in those not elevated. A society of a higher heaven has no communication with a society of a lower except by correspondences (see above, n. 100); and communication by correspondences is what is called influx.
