141. The reason no one is reformed in a state of mental illness is that mental illness deprives us of rationality and therefore of the freedom to act rationally. The mind is sick and not healthy, and while a healthy mind is rational, a sick one is not. The illnesses are things like depression, imagined or illusory guilt, various kinds of hallucinations, mental anguish brought on by misfortunes, and mental anxiety and pain brought on by physical disorders. These are sometimes thought of as temptations, but they are not. Real temptations focus on spiritual issues, and during them the mind is in possession of its skills. The states I am talking about focus on earthly issues, and during them the mind goes mad.

427. And it was given them not to kill them, but to torment them for five months. (9:5) This symbolically means that owing to the Lord's Divine providence it was impossible for them to take away from those without the faith accompanying charity their faculty for understanding and willing truth and good, but only to be able for a short time to induce a mental numbness.

Its being given them means, symbolically, that it was owing to the Lord's Divine providence, as said just above. Their being unable to kill the men lacking the seal of God means, symbolically, that it was impossible for them to take away from those without the faith accompanying charity their faculty for understanding and willing truth and good; for if this faculty were to be taken away from a person, it would kill him spiritually. To torment for five months means, symbolically, to induce a mental numbness for a short time. The number five symbolizes a little something or for a short time, and to torment means, symbolically, to induce a mental numbness, because this is the symbolic meaning of a scorpion (no. 425), and of torment like the torment of a scorpion, as said next in no. 428.

That the faculty of understanding truth and willing it, or rationality and freedom, cannot be taken away from a person, is something we showed many times in Angelic Wisdom Regarding Divine Providence, nos. 73 74, 82-86, 92-99, 138-149, 322.

[2] "Five months" means, symbolically, a little something or for a short time because this is the symbolic meaning of the number five. For periods of time, whether they be hours, days, weeks, months, or years, do not signify a period of time, but a state, and numbers define its character (nos. 4, 10348, 947).

That the number five symbolizes something, and also a little, can be seen from the following passages:

A thousand shall flee... at the threat of five... (Isaiah 30:17)

Five... shall chase a hundred... (Leviticus 26:8)

(Jesus said that) the kingdom of heaven (is like) ten virgins..., five (of whom) were prudent, and five foolish. (Matthew 25:1-2)

The ten virgins symbolize all in the church. Five of them symbolize a part or some.

The like is symbolically meant by the numbers ten and five in the parable in which minas were given to some servants with which to do business, and one of them used his mina to earn ten minas, and a second used his to earn five (Luke 19:13-20). Ten minas symbolize much, and five minas a little. So, too, elsewhere, as in Isaiah 17:6; 19:18, Matthew 14:15-21.
