4175. 'This is how I was: By day the heat consumed me, and the cold by night; and my sleep was banished from my eyes' means temptations. This is clear from the meaning of 'treat' and of 'cold' as that which is the over-abundance of love and that which is the complete lack of it, and so the two extremes - 'day' meaning a state of faith or of truth which is at its height, and 'night' a state when no faith or truth exists at all, 221, 935, 936; and from the meaning of 'sleep banished from the eyes' as constantly or without respite. Because in temptations people undergo experiences such as these, temptations in general are therefore meant by the words used here. The reason 'heat' means an over-abundance of love is that spiritual fire or warmth is love, while spiritual cold on the other hand is the lack of it. In fact man's actual life is nothing other than love, for without love he does not possess any life at all. Indeed, if a person stops to reflect, he can recognize that all vital heat or warmth which is within the body comes from it. But 'cold' does not mean the deprivation of all love, only the deprivation of spiritual and celestial love, a deprivation which is called spiritual death.

[2] When a person is deprived of that love he is fired by love of himself and of the world. This latter love, compared with spiritual and celestial love, is cold, and also becomes cold, not only with a person when living in the body but also when he enters the next life. If love of self and the world is taken away from him when he is living in the body, he grows so cold that he possesses scarcely any life at all, as would likewise be so if he were compelled to think reverently about heavenly and Divine things. In the next life, when such a person is among those who inhabit hell, he is inflamed with the fire or heat of evil passions. But if he draws near to heaven that fire and heat is converted into cold, the intensity of which increases the nearer he gets; and so does the torment to the same extent. This cold is what is meant by 'the gnashing of teeth' which is associated with those in hell, Matthew 8:12; 13:42, 50; 22:13; 24:51; 25:30; Luke 13:28.
