404. Verse 14. And the heaven departed as a book rolled up, signifies that the spiritual man became closed up. This is evident from the signification of "heaven," as being the church in general and in particular; for the church is the heaven of the Lord on the earth; moreover, the church makes one with heaven by conjunction; therefore when "heaven and earth" are mentioned in the Word, the church internal and external is meant, for the internal of the men of the church is heaven with them, and their external is the world with them; and as "heaven and earth" signify the church internal and external so they signify the internal and external man, or the spiritual and the natural man; for as man in whom is the good of love and of faith is a church, so the church, in general exists from the men in whom the church is. This makes clear why it is that "heaven" here means the internal or spiritual man. It is said "the spiritual man," by which is meant the spiritual mind, which is the higher or interior mind of man, while the lower or exterior mind is called the natural man. The above is evident also from the signification of "departed as a book rolled up," as meaning that it became closed up; for the spiritual mind, which is, as was said, the higher or interior mind with man, is opened by truths applied to life, thus by goods, but it is closed up by falsities applied to life, thus by evils; and the closing up is as the rolling up of the scroll of a book. That this is so was made very clear by the appearances in the spiritual world when the Last Judgment was accomplished; for the mountains and the hills there then appeared sometimes to be rolled up as the scroll of a book is rolled up, and those that were upon them were then rolled down into hell. The cause of this appearance was this: that the interiors of their minds, through which somewhat of light from heaven had before flowed in, were then closed up. What takes place in general with many, takes place with everyone in particular of a like character, for in the spiritual world such as the general is, such is the particular (See in the work on Heaven and Hell 73). By "book" is meant a scroll, because in ancient times there were no types and thus no books like those at the present day, but there were scrolls of parchments; so "books" in Revelation mean scrolls, and "heaven departed as a book rolled up" means as a scroll rolled up; the same as in Isaiah:

All the host of the heavens shall waste away, and the heavens shall be rolled up as a book (Isaiah 34:4).

510. And as it were a great mountain burning with fire, signifies the love of self, and of self-intelligence therefrom. This is evident from the signification of "a mountain burning with fire," as being the love of self and the love of self-intelligence therefrom. This love is signified by such a mountain, because a "mountain" in the Word signifies love in both senses, namely heavenly love and infernal love (See above, n. 405); likewise "fire" (See also above, n. 504); and here the evil who are to be separated from the good and cast into hell are treated of, and with such every truth is turned by that love into falsity. This effect, arising from "casting that mountain into the sea," is described in what follows; for "that mountain cast into the sea, so that the third part of the sea became blood," signifies that everything in the natural man became falsity of evil. From this it can be seen that "a great mountain burning with fire" signifies the love of self and the love of self-intelligence therefrom. All self-intelligence is from the love of self.

[2] "Mountain" means love in both senses, because the angels of the third heaven, who are in celestial love, dwell upon mountains in the spiritual world; so when a "mountain" is mentioned, that heaven is meant, and according to the ideas of angelic thought, which are abstracted from persons and places, that which constitutes heaven is meant, that is, celestial love. But in the contrary sense "mountain" signifies the love of self, because they who are in the love of self have a constant desire to go up mountains, to make themselves equal to those who are in the third heaven. Because they dwell upon this in their fancy, it is also the object of their endeavor when they are out of the hells; this is why a "mountain" in the contrary sense signifies the love of self. In a word, those who are in the love of self are always aspiring after high things, so after death, when all the states of the love are changed into things correspondent, in their fancy they mount aloft, believing themselves, while in the fancy, to be upon high mountains, and yet bodily they are in the hells. This is why those who are of Babylon, who are in such love of self as to wish to rule not only over all the earth but also over the heavens, are called "mountains," and are said "to sit upon a mountain" and "to ascend above the heights of the cloud." As in Jeremiah:

Behold, I am against thee, O destroying mountain, destroying the whole earth; and I will stretch out My hand against thee, to roll thee down from the rocks and make thee a mountain of burning (Jeremiah 51:25).

In Isaiah:

Thou hast said in thy heart, I will ascend into the heavens, I will exalt my throne above the stars of God; and I will sit on the mount of the congregation; I will ascend above the heights of the cloud; I will become like the Most High: yet thou shalt be cast down to hell (Isaiah 14:13-15).

This is said of Babylon.
