572. That they should kill the third part of men, signifies of depriving themselves of all understanding of truth, and thus of spiritual life. This is evident from the signification of "to kill," as being to deprive of spiritual life (See above, n. 547); and from the signification of "men," as being the understanding of truth (See also above, n. 546, 547); "the third part," in reference to truths, means all (See above, n. 506); so here "to kill the third part of men" signifies the deprivation of all understanding of truth. It means to deprive themselves, because those who become sensual through evils of life and falsities of doctrine deprive ¹ themselves, by reasonings from fallacies, of the understanding of truth, but not others, except such as are sensual. They thus deprive themselves of spiritual life, because man has spiritual life through his understanding, for he becomes a spiritual man in the measure in which his understanding is opened and permits itself to be enlightened by means of truths. But it is by means of truths from good that the understanding is opened, not by means of truths without good; for man thinks truth so far as he lives in the good of love and charity. Truth indeed is the form of good, and all good with man is of his will, and all truth is of his understanding; therefore the good of the will presents its form in the understanding, and the form itself is thought from the understanding which is from the will.

402. Verse 13. And the stars of heaven fell unto the earth, signifies that the knowledges of good and truth perished. This is evident from the signification of "stars" as being the knowledges of good and truth (See above, n. 72); also from the signification of "falling unto the earth," as being to perish; for when stars fall to the earth they perish. The same is signified by:

The stars shall fall from heaven (Matthew 24:29; and Mark 13:25).

Anyone can see that "stars" here do not mean stars, for these cannot fall from heaven, for they are fixed or established in their place, and cannot fall to the earth, because they are larger than the earth; consequently by them are signified such things as belong to heavenly light, and give light, which are the knowledges of good and truth. Moreover, stars appear in the angelic heaven, but they are appearances from the knowledges of good and truth, therefore they appear about those who are in such knowledges, especially when they turn them over in the mind, and are desirous of knowing them.
