“The earliest people, who were heavenly, did actually see 
everything they looked at on earth and in the world around them, but 
their thoughts were devoted to the heavenly or divine attribute it 
symbolized or represented. Vision was just a means." (Secrets of Heaven, 241)
According to Swedenborg, the earliest group of people to inhabit 
the world saw everything in it as a symbol that represented heavenly 
realities. When they saw a mountain, they didn't just see a large hunk 
of rock--they saw implicit in it a representation of mankind's 
coming-close to God. Likewise, he says that when this people saw bodies of water, they understood them to represent divine truth, and when they saw the sun
 they understood it as a representation of God Himself. In 
that respect, their attention didn't rest upon any concerned thing in 
itself; rather, they would see it as a window through which they could 
discern a unique aspect of God and Heaven. He even goes on to say that they understood the world through these symbols like we understand a 
person's vocal sounds through the meaning inherent in them, to the point
 where it likewise required no effort on their part.
Honestly, Swedenborg's claims are not that outlandish. The 
ethnologist Lucien Lévy-Bruhl and later Carl Jung made the well-known claim 
that primitive people (that is, cultures similar in kind to what we can 
assume that Swedenborg meant by the "earliest people") engage in what 
they call a "participation mystique" (mystic participation) with the 
objects, animals, and people around them. This essentially means that 
they don't divorce their inner psychic life from their life in the 
world--what goes on "inside" and what goes on "outside" completely 
overlap. Just as Swedenborg's first people "saw through" everything to 
the spiritual realities underlying them, Jung and Lévy-Bruhl claim that 
primitive humans see through every outside object to the symbolic 
processes occurring in either an individual or a collective soul.
Moreover, the fact that nearly all mythologies share in the same 
basic archetypes and images also provides support to Swedenborg's claim.
 Whether in tribal or more developed contexts, the sky god is almost 
always male and a father, and the earth goddess is almost always female 
and a mother (this even shows up in our language: the root for "matter" 
is "mater," as in "maternal"). And as Jung often pointed out, archetypes such as "the wise old man," "the hero," "the trickster," and "the 
Shadow" occur repeatedly not only in mythology, but also in literature 
and pop culture. Again and again, one sees the proliferation of these 
archetypal symbols in both our culture and those of others, and it gives
 the impression that Swedenborg's claim of our innate connection to a 
world of divine symbols may not be so crazy.
And Swedenborg claims exactly that: that our native heavenly world
 is an innately symbolic place, where a state of mind cannot occur 
without the projection of an image that corresponds to it. Moreover, 
that world "symbolizes with" ours, for Swedenborg repeatedly asserts 
that one draws closer to something in the spiritual world the more 
similar in state to it one becomes. And it is this divine faculty for 
symbolic association that his  "earliest people" used to see through the
 physical world, for by doing so, they would come into contact with the 
heavenly reality that symbolically underlies them.
Nor is this symbolic perspective entirely alien to Mormon thought.
 Not only does Alma the Younger speak of people receiving God's image in their countenances (Alma 5:14) or Joseph Smith speak of "all things [having] 
their likeness, [...] that they may accord one with another--that which 
is earthly conforming to that which is heavenly" (D&C 128:13), but 
one can even understand the central concept of priesthood ordinances in 
such a symbolic way. According to this perspective, a priesthood 
ordinance such as the Sacrament is a symbolic manifestation of a 
heavenly reality, relating to that reality much in the same way that a 
spoken word does to its meaning. Christ's body and his sacrifice shine 
forth from "behind" the bread and water, and if we have but eyes to see,
 we can discern their manifest presence in the ritual sustenance.
Indeed, one could say that our emphasis on ritual ordinances 
actually invites us to see the world in symbolic terms. If there is 
something more to the Sacrament than a paltry meal, and if a priesthood 
blessing is more than just a bunch of sweaty palms, the world must be 
innately more than the common literal perception of it suggests. 
For just as an ordinance may convey divinity, nothing stops you from 
seeing a divine hand in an outwardly insignificant act of kindness by a 
stranger, or even from seeing the countenance of a dead family member in
 someone alive (as routinely happens when we do ordinances for the 
dead).
But the question arises: if we have become disconnected from our 
natural capacity to discern heavenly realities through the physical 
world, what can we do to get it back? The answer is very simple, and I 
can give it in one word: love. To echo The Little Prince's  resounding
 maxim, the eyes are blind to higher spiritual realities, and one can 
only discern them with the heart. It is by cherishing, nurturing, 
protecting, and caring for the beloved that one can discern the 
spiritual realities exemplified through him or her. Indeed, one can say 
that by shedding the light of care upon this person, one "frees" the 
latent spiritual realities from their hiddenness within him or her, for 
love really is a process of unveiling the hidden spiritual 
potentialities within a person. Of course, it doesn't even have to be a person--I believe that animals too can be discerned in such a way, as anyone who has loved a pet will know.
Nor are even inanimate objects excluded from love's "freeing" 
effects. Just as one can find God in a piece of bread or a small cup of 
water, nothing prevents you from "seeing through" an everyday physical 
object to the spiritual realities latent within it. This, at least, 
makes sense of Joseph Smith's exhortation to:
"Let the mountains shout for joy, and all ye valleys cry aloud;
 and all ye seas and dry lands tell the wonders of your Eternal King! 
And ye rivers, and brooks, and rills, flow down with gladness. Let the 
woods and all the trees of the field praise the Lord; and ye solid rocks
 weep for joy!" (D&C 128:23)
In a very real sense, we can bring the inanimate to life through 
our attention and care for it. The French philosopher Gaston Bachelard 
says volumes on this subject in his work The Poetics of Space (link), 
where he speaks of how one's childhood home has a living character that,
 though lost, can come to life again through our feelings of intimacy 
and at-home-ness. In the same work, Bachelard pens these moving words 
about the freeing of the material world from its literal confinements:
"When insomnia, which is the philosopher's ailment, is 
increased through irritation caused by city noises, the hum of 
automobiles and trucks rumbling  through the Place Maubert causes me to 
curse my city-dweller's fate, I can recover my calm by living the 
metaphors of the ocean. [...] If the hum of cars becomes more painful, I
 do my best to discover in it the roll of thunder, of a thunder that 
speaks to me and scolds me. And I feel sorry for myself. So there you 
are, unhappy philosopher, caught up again by the storm, by the storms of
 life! I dream an abstract-concrete daydream. My bed is a small boat 
lost at sea; that sudden whistling is the wind in the sails. On every 
side the air is filled with the sound of furious klaxoning. I talk to 
myself to give myself cheer: there now, your skiff is holding its own, 
you are safe in your stone boat. Sleep, in spite of the storm. Sleep in 
the storm. Sleep in your own courage, happy to be a man who is assailed 
by the wind and wave. And I fall asleep, lulled by the noise of Paris."
To me, the most unfortunate fault of modern humanity is its 
unwillingness to leave the literal perspective. For without a 
perspective that symbolizes meaning out of the literal world, that world
 will remain dead. But that is not its destiny. Out of the seemingly 
immovable world of parking lots and queues of people at the grocery 
store, we should instead discern a divine drama enacted at every moment 
and in every seeming insignificance. My desk is not just a chair--with 
my love and attention it becomes a throne or a cathedral pew. Likewise, 
in my friend's compassion I can see Christ Himself reaching out to the 
young woman caught in adultery, and in my significant other I may 
perhaps discern both her latent divine individuality (talked about in this post) and the feminine aspect of divinity (talked about in this post).
But there is more to be said. The scriptures speak of a time in 
the indefinite future when all things will return to their original 
state, uncorrupted by the accidents of this world. In this, the 
resurrection, the physical and the spiritual will completely coincide 
with each other. The spiritual and the physical then finally 
meet together as equal partners, ready to take their places side by side
 in the eternities. But how does this happen? The science of a 
resurrected world is not very clear, but Swedenborg gives us another 
perspective to consider: that just as the ancient peoples saw the 
heavenly realities through the world's seeming opacity, we are destined 
to do so again. Then Christ Himself will step out from behind his veil 
of shadows and reveal to us that He had always been there with us, for 
even now He says that "I am in your midst and ye cannot see me" (D&C
 38:7). Then all the hosts of heaven will unveil themselves and fall 
upon our necks, just as we will fall upon theirs (Moses 7:63). Finally, 
the earth will reveal itself as what it always was for those who had 
eyes to see: a great Urim and Thummim, "a globe like a sea of glass and 
fire, where all things for [our] glory are manifest, past, present, and 
future" (D&C 130:7-9).
I look forward to that day, and I look forward to the miniature 
versions of it that happen every time I show love to a person, an 
animal, or even a cherished object. For this is our duty: to show love 
to God's creations, and, by doing so, setting them free to dance before 
us in the light of God.
