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.
