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.

'A temple' represents heaven and the church. The sacred place where the ark was, represents the inmost, or third heaven, and the church among people in the inmost principle, called the celestial church. The temple outside the sacred place represents the middle, or second heaven, and the church with people in similar principles, called the internal spiritual church. The inner court represents the outermost or first heaven, also the church with people in outer degrees, called the internal natural church. The outer court represents entrance into heaven.

'Temple,' as in Revelation 15:8, signifies divine truth, or the Word in the natural sense, in light and power from the divine truth in the spiritual sense.

'I saw no temple in it,' as in Revelation 21:22, does not mean that in the new church, which is New Jerusalem, there will be no temple, but that externals will not be separated from internals. This is because 'a temple' signifies the church regarding worship, and in the highest sense, the Lord Himself regarding the divine humanity, who should be worshiped. Because the whole church is from the Lord, it says, 'for the Lord God Omnipotent and the Lamb is the temple thereof,' which signifies the Lord in His divine humanity.

'Temple,' as in Luke 21:5-7, signifies the church at this day, in which there is no truth left remaining, and as a result, is at an end.

'Temple' signifies the higher heavens.

'Temple' signifies the Lord's divine human with respect to divine truth.

'The temple of His body,' as in John 2:21, signifies the divine truth from the divine good.
