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).

476. And have made their robes white in the blood of the Lamb, signifies the implantation of Divine truth from the Lord. This is evident from the signification of "making robes white," as meaning to put off falsities and to put on truths, for "white" and "to be made white," are predicated of truths, and these are signified by "robes." (That "white" and "to be made white," are predicated of truths, see above, n. 196; and that "robes" signify truths in general see above, n. 395.) It is said "made their robes white," because the garments of those who are in falsities appear in the spiritual world dusky and also spotted, and the garments of those who are in temptations appear filthy; but as soon as they emerge from temptations, as they have then been imbued with Divine truths, white and shining garments without spots appear upon them, as was mentioned just above. This is why "they have made their robes white" signifies that they have put off falsities and put on truths. The above is evident also from the signification of "the blood of the Lamb" as being Divine truth proceeding from the Lord (of which above, n. 329 e New Jerusalem 293, 294, and in the extracts there from the Arcana Coelestia.) This can be seen from this also, that the garments of angels appear glistening from what is white and bright, not from faith in and thought about the blood of the Lord on the cross, but from Divine truth with them from the Lord; for, as was said above, their garments are all in accord with the truths with them; nor is any angel permitted to think of the Lord's passion, but only of His glorification, and of the reception by Him of the Divine.); and because in temptations falsities are shaken off, and truths are implanted, so in general, "they have made their robes white in the blood of the Lamb" signifies the implantation of Divine truth from the Lord. In the sense of the letter of the Word, "the blood of the Lamb" means the passion of the cross, but in the internal or spiritual sense it means Divine truth proceeding from the Lord; for it is by this that man is purified from falsities and evils, that is, his garments are made white. The passion of the cross was the Lord's last temptation, by which He fully subjugated the hells, and glorified His Human; and when this was accomplished and completed, the Lord sent the Comforter, the Spirit of Truth, by which is meant Divine truth proceeding from His glorified Human, as the Lord teaches in John (John 7:39) and elsewhere. It is by means of Divine truth, when it is received, that man is reformed and regenerated by the Lord and saved, and not by the shedding of blood on the cross. (On this more may be seen in The Doctrine of the New Jerusalem 293-294.)
