84. Because these two worlds are so distinct from each other, it is quite obvious that the spiritual world is under a different sun than is the physical world. There is just as much warmth and light in the spiritual world as there is in the physical world, but the warmth there is spiritual and so is the light. Spiritual warmth is the good that thoughtfulness does and spiritual light is the truth that faith perceives.

Now, since the only possible source of warmth and light is a sun, it stands to reason that there is a different sun in the spiritual world than there is in the physical world. It also stands to reason that because of the essential nature of the spiritual world's sun, spiritual warmth and light can come forth from it, while because of the essential nature of the physical world's sun, physical warmth [and light] can come forth from it. The only possible source of anything spiritual--that is, anything that has to do with what is good and true--is divine love and wisdom. Everything good is a result of love and everything true is a result of wisdom. Any wise individual can see that this is their only possible source.

525. Many people who arrive in the other life from the Christian world bring with them a faith that they are going to be saved out of straight mercy, because they plead for it. When they are examined, though, it turns out that they have believed that getting into heaven was simply a matter of being let in, and that people who had been admitted were in heavenly joy. They have had no notion of what heaven is or what heavenly joy is. So they are told that the Lord does not deny heaven to anyone. They can be let in if they wish and even stay there. Some who wanted to were actually let in; but at the very threshold, at the touch of heaven's warmth (that is, of the love angels are engaged in) and the inflow of heaven's light (which is divine truth), they were seized with such pain in the heart that they felt themselves in the torments of hell rather than in the joys of heaven. Struck by this, they plunged down headlong. In this way they were taught by firsthand experience that no one can enter heaven out of straight mercy.
