137. [138] A great number of those who are in faith separate from charity betake themselves to rocks; while those who are in the love of self betake themselves to mountains which are higher than the rocks. Hence it is that in the Word, a rock signifies faith, and a mountain love. And when, before the Last Judgment, the evil had been thus gathered together upon rocks and upon mountains, first there were suddenly felt concussions and earthquakes, by which are meant perversions of state in respect to the church, and afterwards follows the overturning, which is effected either by sinking, or by carrying away, or by casting out and thus thrusting down into hell. On the mountains and hills upon which are angels, the wisest are in the middle and the less wise at the circumferences; but on those upon which are the evil, the worst are in the middle and the better at the circumferences. The sinking in the middle appears like a vortical gyration, but in a spiral.
