505. And they were cast unto the earth, signifies progression towards the lower parts, where the evil were. This is evident from the signification of "being cast unto the earth," namely, "hail and fire mingled with blood," which was effected by "the first angel sounding," as being to advance towards the lower parts, where the evil were consociated, with whom also there were some of the good. This signifies progression towards the lower parts, because the changes and desolations that are signified by "the third part of the trees and all the green grass were burnt up," were effected progressively towards the lower parts where the evil were, as has been said above. "The earth" means here the lower parts, because these things were seen by John when he was in the spirit, that is, when he was in the spiritual world; for man's spirit, when it has its sight opened, sees the things that are in the spiritual world and in that world there are mountains, hills, and valleys, and upon the mountains and hills there are the angelic heavens, but in the valleys below are those who have not yet been taken up into heaven; on these, therefore, there were now the evil mixed with the good; wherefore these valleys that were below the mountains and hills are here meant by "the earth" (or land); so "to be cast unto the earth" means out of the heavens towards the lower parts. But when mountains, hills, and valleys taken together are called "the earth," then "the earth" signifies the church there.

302. Verse 2. And I saw a strong angel proclaiming with a great voice, signifies exploration by the influx of the Lord into heaven. This is evident from the signification of a "strong angel," as being heaven (of which presently); also from the signification of "proclaiming with a great voice," as being exploration by the influx of the Lord, namely, exploration whether anyone is able to know the states of life of all in heaven and on the earth in general and in particular, for this is what is here treated of. This is signified by "proclaiming," and the influx of the Lord is signified by "a great voice;" for "voice," in reference to the Lord, signifies every truth of the Word, of doctrine, and of faith from Him; and in reference to heaven and the church, it signifies every thought and affection thence; and since everything true and good that angels in heaven and men in whom the church is, think and are affected by, is from the influx of the Lord, this is what is here signified by "a great voice." For it is well known, that no one from the love of good can be affected by good, and from the love of truth can think truth, of himself, but that this flows in from heaven, that is, through heaven from the Lord; and because this is so, "a great voice" signifies the influx of the Lord. (That "voice" in the Word signifies the truth of the Word, of doctrine, and of faith, also everything announced in the Word, see above, n. 261, and Arcana Coelestia 3563, 6971, 8813, 9926; and that it signifies the interior affection of truth and good, and thought therefrom, n. 10454) A "strong angel" signifies heaven because the whole angelic heaven before the Lord is as one man, or as one angel, likewise each society of heaven; therefore by "angel" in the Word an angel is not meant, but an entire angelic society, as by "Michael," "Gabriel," "Raphael." Here, therefore, "a strong angel proclaiming with a great voice" signifies the influx of the Lord into the whole heaven. That it is into the whole heaven is clear from what follows, for it is said, "And no one was able, in heaven nor upon the earth, neither under the earth, to open the book and to look thereon." (That "angels" in the Word mean entire societies of heaven, and in the highest sense the Lord in respect to Divine truth proceeding, see above, n. 90, 130, 200; and that The Whole Heaven before the Lord is as One Man, or as One Angel, and also every Society of Heaven, see in the work on Heaven and Hell 59-87.)
