134. Heaven's warmth, like heaven's light, is different in different places. It has one nature in the heavenly kingdom and another in the spiritual kingdom. It also differs in each community, not only in intensity but in quality. It is more intense and pure in the Lord's heavenly kingdom because the angels there accept more divine good. It is less intense and pure in the Lord's spiritual kingdom because the angels there accept more divine truth. In each community, it varies depending on people's receptivity. There is also warmth in the hells, but it is unclean. ¹

The warmth in heaven is meant by sacred and heavenly fire, and the warmth of hell by profane fire and hellfire. Both refer to love: heavenly fire to love for the Lord and love for one's neighbor, and hellfire to love for oneself and love of the world and all the craving that is associated with these loves. ²

The fact that love is warmth of a spiritual origin can be seen from the way we grow warm in proportion to our love, even becoming inflamed and heated in proportion to its intensity and quality, with its full heat evident when we are attacked. This is why it is usual to talk about inflaming, heating up, burning, boiling, and kindling when we are talking about either the affections of a good love or the cravings of an evil love.

Footnotes:

61. Our whole spirit is desire and its consequent thought; and since all desire is a matter of love and all thought a matter of discernment, our whole spirit is its love and its consequent discernment. This is why our thinking flows from the desires of our love when we are thinking solely from our own spirit, as we do when we are in reflective moods at home.

We may conclude, then, that when we become spirits (which happens after death), we are the desire of our love, and not our thought except to the extent that it comes from that desire. We are drawn to what is evil (which amounts to a compulsion) if our love has been a love for what is evil, and we are drawn to what is good if our love has been a love for what is good. We are drawn to what is good to the extent that we have abstained from evils as sins; and we are drawn to what is evil to the extent that we have not abstained from evils.

Since all spirits and angels are desires, then, we can see that the whole angelic heaven is nothing but a love that embraces all desires for what is good and therefore a wisdom that embraces all perceptions of what is true. Further, since everything good and true comes from the Lord and the Lord is love itself and wisdom itself, it follows that the angelic heaven is an image of him; and since divine love and wisdom are human in form, it also follows that this is the only possible form the angelic heaven can have. But I will have more to say about this in the next section.
