457. Almost all who pass from this world into the other life suppose that hell is the same for everyone, and that heaven is the same for everyone. And yet in both there are endless, diversities and varieties, and neither the heaven nor the hell of one person is ever exactly like that of another; just as no man, spirit, or angel is ever exactly like another. When I merely thought of there being two exactly alike or equal, horror was excited in the inhabitants of the world of spirits and of the angelic heaven, and they said that everyone is formed by the harmony of many components, and that such as is the harmony, such is the one, and that it is impossible for anything to subsist that is absolutely a one, but only a one that results from a harmony of component parts. Thus every society in the heavens forms a one, and so do all the societies together, that is, the universal heaven, and this from the Lord alone, through love. A certain angel enumerated the most universal only of the genera of the joys of spirits, that is, of the first heaven, to about four hundred and seventy-eight, from which we may infer how innumerable must be the less universal genera and the species in each genus. And as there are so many in that heaven, how, illimitable must be the genera of happinesses in the heaven of angelic spirits, and still more so in the heaven of angels.
