Correspondence is the relationship between a natural thing and its spiritual meaning, and it exists according to that thing's use. The spiritual world and the natural world correspond; forms exist here because their purpose exists there. Sacred text such as in the Bible has outward form and inner meaning and the two are in complete correspondence.

This can be illustrated by the following example: when you see someone you love, you smile. It seems like a pretty simple process, but in reality, it's not; instead it’s a whole string of events, with simpler things relating to more complex ones, rising to the spiritual level and coming back down. First light bounces off that person’s face and enters your eyes. Your eyes send information to your brain. From there it passes into your mind - a spiritual organ, according to Swedenborg’s works - and registers in your consciousness. You recognize the person and feel love for them! But that has to get translated back down through the brain, which generates signals to all the facial muscles, which then contract or relax according to orders, producing a smile.

As you can see, the real activity here is mental. You “see” that face in your mind; before then it’s just a string of impulses carrying information. And you “smile” in your mind, with the information translated back into more impulses carry more information leading to physical activity. Your eyes don’t “know” what they’re seeing; your cheeks don’t “know” that they are smiling. They are simply projections of an internal, spiritual thing - your mind - into a lower physical reality.

That’s an example of correspondences, on a very small scale. What you see on the natural plane of existence corresponds to your idea of what you see and the affection you have for it. Your reaction in turn corresponds to the affection you have. The correspondence of one with the other is a way for the more important spiritual reality - the activity in your mind - to project itself into physical reality.

Swedenborg’s works tell us that those correspondences are more important than we could possibly imagine. In fact, everything in the physical world corresponds to something in the spiritual world. Mountains, for example, are not just mountains; they are the spiritual love of the Lord projected into physical reality in the form of mountains. Trees are rooted, lasting spiritual principles projected into physical reality in the forms of trees. A river is a flow of true spiritual ideas projected into physical reality. In a way, it’s like the spiritual world is one huge collective mind, expressing itself through physical reality the way our own minds express themselves through our own bodies.

And then there’s another level: Swedenborg’s works say that the most perfect form of spiritual reality, heaven, is in a state of complete, all-encompassing correspondence with the Lord, with each aspect of heaven expressing some aspect of the deepest reality of all, which is the Lord’s love and wisdom themselves. This is way out at the raw edge of what we can grasp, but it’s really quite beautiful. Spiritual reality is not part of the Lord, but it is from the Lord and can express the Lord as it approaches perfection. Physical reality is not part of the Lord and is not part of spiritual reality, but it is from the Lord by way of spiritual reality, and it can express spiritual reality (and thus the Lord) as it approaches perfection.

This is why the Lord had so many physical laws for the children of Israel: the prescribed physical actions corresponded to spiritual meanings, which in turn corresponded to aspects of the Lord Himself. It explains why we see advanced astronomy and awareness of nature in the remnants of ancient religions worldwide: They came from the Ancient Church, which had a surpassing knowledge of correspondences and used that knowledge in worship and life. To some degree it explains why we still love mountaintops, beautiful gardens, natural beauties like waterfalls: we can still feel the spiritual reality close inside them, even if we don’t know it in its specifics.

Correspondences also explain the continuing power of the Bible even in this skeptical age. The Lord provided that it should be written - most of it, anyway - in correspondences, which actually give access to His whole infinite being. We may not understand them, but that does not limit their power to teach us, to form our minds; this is why it’s important for people to read the Bible with open minds, to let the Lord enter in.

One other fascinating and meaningful aspect of correspondences comes in the form of what Swedenborg’s works call the “Grand Man” or “Grand Human.” Because heaven is in complete correspondence with the Lord and the Lord is the ultimate, infinite, divine and archetypal human, this means that heaven is in human form. And this is quite literal and precise: parts of heaven correspond the heart, others to the lungs, others to the brain, skin, ears, hair, digestive tract, everything. What’s more, just as the body’s organs are broken down into tissues and the tissues into cells, so also is the Grand Human broken down. So as an individual angel you might serve a brain function for a cell that performs a protective function for an organ that plays a digestive role in the Grand Human. That sounds a bit strange, but if you consider the unique mix of ideas and affections in each of us you can see how we could, indeed, fill such precise roles calling for such precise degrees of precisely layered talents.

And since physical reality is in correspondence with spiritual reality, this means that our communities and societies in this world are also in the human form, though obviously not all to a very perfected degree. This also sounds strange, but it’s an interesting exercise to think about the functions of the brain (to think and judge), the skin (to protect and hold together), the lungs (to draw in new thoughts and ideas), the digestive tract (to create energy to do work), heart (to circulate energy and ideas) and muscles (to do the actual work) and relate them to the functions of human organizations. Most likely, effective human organizations will indeed have these elements, and will have them in the proper balance.

Finally, of course, correspondences are one of the primary reasons for this website to exist. Our purpose is to share the knowledge of correspondences offered through Swedenborg’s works, so we can all understand the Bible, the Lord and ourselves a little bit better and find our own places in the Grand Human.

90. Since a human being is a heaven and a world in least form in the image of the greatest (see 57 above), there is a spiritual world and a natural world within each of us. The deeper elements, which belong to our minds and relate to our intelligence and volition, constitute our spiritual world, while the outer elements, which belong to our bodies and relate to our senses and actions, constitute our natural world. Anything that occurs in our natural world (that is, in our bodies and their senses and actions) because of our spiritual world (that is, because of our minds and their intelligence and volition) is called something that corresponds.

3747. I have spoken on several occasions to spirits about the learned of our own day who know of the distinction in the human being between internal and external but nothing more beyond this; nor do they know even this from reflecting on the interior aspects of their own thoughts and affections but from the Word of the Lord. They do not know what the internal man is, and what is more very many doubt and even deny the existence of it, the reason being that they are not living the life of the internal man but of the external. I have also spoken to those spirits about many a thing that may lead the learned astray, such as the fact that animals seem to be like themselves so far as organs, viscera, senses, appetites, and feelings are concerned. It has been said in our discussions that the learned know less about such matters than the simple, even though they seem to themselves to know far more. For they argue about the interaction of the soul and the body, and indeed about what the soul itself may be, whereas the simple know that the soul is the internal man and that it is a person's spirit which is going to live after death of the body, and also that it is the real person himself who is within the body.

[2] It has been added that the learned more than the simple equate themselves with animals, ascribing all things to natural forces and scarcely anything to the Divine. Nor do they stop to reflect that man, unlike animals, is able to think about heaven and about God, and in so doing to be raised above himself, and consequently to be joined to the Lord by means of love; and that for these reasons they must inevitably live for ever after death. We have gone on to refer to their particular ignorance of the fact that every single thing with man traces back to the Lord through heaven, and that heaven is the Grand Man to which every single thing in man corresponds, as does everything in the natural system. And when perhaps they hear or read of these things they will be to them so paradoxical that unless experience proved the truth of them they would reject them as something delusive. It is similar when they hear that there are three degrees of life in man just as there are three degrees of life in heaven, that is, there are three heavens, and that man corresponds to the three heavens in such a way that in image he is a small-scale heaven when he leads the life of good and truth and through that life is an image of the Lord.

[3] I have been told the following about those degrees of life: The ultimate degree of life is that which is called the external or natural man, which makes man similar to animals so far as his pressing desires and his delusions are concerned. The second degree is that which is called the internal or rational man which makes man superior to animals. For by means of the internal man he is able to think and to will what is good and true and to govern the natural man by controlling his desires and disregarding his resulting delusions, and on top of this by reflecting within himself about heaven, indeed about the Divine, which animals are quite incapable of doing. I have been told that the third degree of life is one which is totally unknown to man, and yet it is the degree through which the Lord enters into the rational mind, from which he has the ability to think as a human being, to have conscience, to have perception of what is good and true, and to be raised up by the Lord towards Himself. These considerations however are remote from the ideas of the learned of this present age, who do no more than dispute whether the internal man exists at all. And as long as they cannot be sure that it exists they are even less able to know what it is.
