418. Again, the immensity of the heaven of the Lord is shown in this, that heaven in its entire complex reflects a single Man, and corresponds to all things and each thing in man, and that this correspondence can never be filled out, since it is a correspondence not only with each of the members, organs, and viscera of the body in general, but also with all and each of the little viscera and little organs contained in these in every minutest particular, and even with each vessel and fiber; and not only with these but also with the organic substances that receive interiorly the influx of heaven, from which come man's interior activities that are serviceable to the operations of his mind; since everything that exists interiorly in man exists in forms which are substances, for anything that does not exist in a substance as its subject is nothing. There is a correspondence of all these things with heaven, as can be seen from the chapter treating of the correspondence of all things of heaven with all things of man (n. 87-102). This correspondence can never be filled out because the more numerous the angelic affiliations are that correspond to each member the more perfect heaven becomes; for every perfection in the heavens increases with increase of number; and this for the reason that all there have the same end, and look with one accord to that end. That end is the common good; and when that reigns there is, from the common good, good to each individual, and from the good of each individual there is good to the whole community. This is so for the reason that the Lord turns all in heaven to Himself (see above, n. 123), and thereby makes them to be one in Himself. That the unanimity and concord of many, especially from such an origin and held together by such a bond, produces perfection, everyone with a reason at all enlightened can see clearly. 419. I have also been permitted to see the extent of the inhabited and also of the uninhabited heaven; and the extent of the uninhabited heaven was seen to be so great that it could not be filled to eternity even if there were many myriads of earths, and as great a multitude of men on each earth as on ours. (On this also see the treatise on The Earths in the Universe, n. 168.)
