An excerpt from Heaven and Hell by Emanuel Swedenborg, sections #17–19
All my experience in heaven bears witness to the fact that the divine nature that comes from the Lord, affects angels, and constitutes heaven, is love. In fact, all the people there are forms of love and thoughtfulness. They look indescribably beautiful. Love radiates from their faces, from their speech, from every detail of their behavior.
Further, there are surrounding auras of spiritual life that emanate from every angel and from every spirit and envelop them. By means of these auras one can recognize even from a distance the quality of the affections of their loves, since these auras flow out from the life of their affection and consequent thought—that is, from the life of their love and consequent faith. The auras that emanate from angels are so full of love that they touch the deepest reaches of life of the people they meet. I have been aware of them a number of times, and they have moved me deeply.
I have been able to see that love was the source of angels’ life because all the people in the other life turn in a direction determined by their own love. People engaged in a love for the Lord and a love for their neighbor are constantly turning toward the Lord, while people who are engaged in self-love are constantly turning their backs to the Lord. This holds true no matter which way they turn, since in the other life spatial relationships are determined by people’s inner natures. These also determine geographical regions, whose boundaries are not drawn the way they are in the physical world but depend on which way people are facing. Actually, it is not angels who turn to the Lord but the Lord who turns toward himself the people who love to do whatever has its source in him. But there will be more on this subject below, when we discuss geographical regions in the other life.
The reason the Lord’s divine nature in heaven is love is that love is what is receptive of every heavenly quality—that is, of peace, intelligence, wisdom, and happiness. Love is receptive of everything that is in harmony with it. It longs for such things, it seeks them out, it absorbs them spontaneously because it has the constant purpose of uniting itself with them and being enriched by them. People actually recognize this fact, since the love within them surveys memory, so to speak, and draws out from it the items that agree with it. It gathers these together and arranges them within and beneath itself—within itself so that it may possess them and beneath itself so that they may serve it. It discards and eradicates, though, the items that do not agree with it.
I have been able to see very clearly that love has a full, intrinsic ability to accept elements of truth that suit it and has also a desire of uniting them to itself. This has become clear from observing people who have been transported into heaven. Even people who were simple folk in this world have arrived at angelic wisdom and heavenly happiness in the company of angels. This was because they loved what is good and true for the sake of what is good and true. They had grafted these qualities into their lives and had thereby become capable of accepting heaven and all its indescribable riches.
People caught up in love for themselves and for the world, however, have no such receptive ability. They turn away from such things, discard them, and at their first touch or inflow try to escape them. They ally themselves with people in hell who are caught up in loves like their own.
There were some spirits who doubted that love was so full and wanted to know whether this was really true. In order that they might find out, they were let into a state of heavenly love with all obstacles removed and were brought forward a considerable distance to an angelic heaven. They talked with me from there and told me that they felt deeper happiness than words could express, sorrowing that they would have to return to their former state. Other people as well have been raised into heaven, and the deeper or higher they have been taken, the deeper and higher they have penetrated into intelligence and wisdom, becoming able to grasp things that were incomprehensible to them before. We can see from this that the love that emanates from the Lord is open to heaven and all its riches.
We can conclude that love for the Lord and love for our neighbor embrace within themselves everything that is true from the Divine because this follows from what the Lord himself said about these two loves: “You shall love your God with all your heart and with all your soul: this is the greatest and first commandment. The second, which is like it, is that you should love your neighbor as yourself. On these two commandments depend the Law and the Prophets” (Matthew 22:37–40). The Law and the Prophets are the whole Word, which means all divine truth.
