Hello again, dear friend.
Last time we sat together, we were in the young and restless streets of New York, following a woman named Elizabeth who turned her grief into something that fed thousands of hungry souls. I think of her often. She knew what it meant to tend what mattered.
Today I want to take you somewhere much older. Much higher. The air is thinner where we are going, and the mountains are enormous, and the sky above the Andes at dawn is a color I have never seen anywhere else in the world --- a deep, cold blue that feels like the beginning of everything.
There is a place there. A place I have returned to many times over the centuries, just to stand at its edge and look down into it and remember what a civilization can know when it listens carefully enough.
You will not have heard of it, most likely. It doesn't get the attention it deserves. But I think, once you see what I see, it will stay with you.
Come. Let me show you Moray.
I want you to imagine that you are standing on the edge of something that should not exist.
You are on a high plateau in the Andes mountains of Peru. Three thousand five hundred meters above sea level --- that is nearly eleven and a half thousand feet. The air is cold and clean and thin enough that you are aware of your own breathing. The mountains rise around you in every direction, ancient and unhurried. The sky is enormous.
And then the ground disappears.
Not in a frightening way. Not a cliff, not a collapse. Just --- an absence, where a moment ago there was solid earth. You step to the edge and look down, and what you see stops you completely.
A perfect circle. Ringed by concentric terraces of fitted stone, descending in steps toward a shadowed center far below. Then another circle beside it, slightly smaller. Then another. The largest is nearly six hundred feet across. Each one descends about thirty meters into the earth --- terraced all the way down, level by level, like the rings of some ancient tree seen in cross-section, or like a staircase built for a giant who wanted to descend very, very slowly into the heart of the world.
The precision is what gets you first. These are not rough earthworks. The stones fit. The levels are even. The whole thing is so geometrically exact that your modern eye reads it as engineered --- industrial, almost. You find yourself thinking of open-pit mines, of quarries, of construction sites.
And then something shifts.
You notice the irrigation channels, barely visible, threading through each terrace. You notice that the bottom of the circle is still in shadow while the top terraces are already catching the morning sun. You notice that the air rising from the lowest level feels --- different. Warmer. And you begin to understand that this place was not built to take something out of the earth.
It was built to put something in.
Seeds. Knowledge. Patience. Care.
I have seen amphitheaters built for war and for music and for spectacle. I have stood in stadiums built to celebrate the power of empires. This is none of those things. This is a place built to understand how life grows. And standing at its rim, looking down into those perfect descending rings, I find I cannot decide whether it is more like a laboratory or more like a temple.
I wonder if the people who built it would have understood the difference.
To understand Moray, you first have to understand the world it came from.
I have watched many empires rise. Most of them organized themselves around the same ideas --- power at the center, tribute flowing inward, the many laboring for the few. I have seen it so many times that I sometimes wonder if humanity has any other moves.
And then I found the Andes.
The Inca Empire --- known in Quechua as Tawantinsuyu, the Land of the Four Quarters --- rose to power in the early fifteenth century and at its height stretched nearly two thousand five hundred miles down the western spine of South America. From what is now southern Colombia to central Chile. From the Pacific coast to the edge of the Amazon. It encompassed more than a hundred distinct ethnic groups. Somewhere between ten and twelve million people called it home.
And it ran without money.
I want you to sit with that for a moment, because I did. No coins. No markets. No trade economy in the sense we understand it. The organizing principle of Inca civilization was something the Quechua language calls ayni --- reciprocity. You give what you have. The community gives back what you need. The emperor receives labor. The emperor feeds and clothes and protects those who labor. The earth receives your care. The earth feeds you in return. It was a moral system as much as an economic one. And I watched it work. I watched it feed twelve million people across the most vertical, difficult, impossibly varied landscape on earth. Without wheels. Without draft animals for farming. Without iron tools.
I have never quite gotten over it.
Agriculture was the beating heart of all of this. And agriculture, for the Inca, was not merely practical --- it was sacred. Which brings us back to the plateau, and to Moray.
The site sits about fifty kilometers northwest of Cusco --- the great Inca capital, the navel of the world as its people called it --- on a high plain called the Chinchero plateau. I should tell you that the place was already old when the Inca arrived. Archaeologists believe the lower terraces were first laid down by an earlier culture, possibly the Wari, somewhere between the sixth and tenth centuries. The Inca inherited what they found and built upward and outward, completing the complex during their great period of expansion.
What they completed was this: three groups of circular terraces descending into natural depressions in the earth. The largest circle has twelve levels and drops roughly thirty meters from rim to floor. The temperature difference between the topmost terrace and the lowest can reach fifteen degrees Celsius. The Inca engineered that difference deliberately --- the orientation of each circle relative to the sun and prevailing winds was carefully calculated. They built irrigation channels into every level, fed by a reservoir higher in the mountains. And --- this is the detail I find most quietly astonishing --- soil samples from the terraces show that the earth itself was carried in from other regions. They brought dirt from distant climates and laid it at the appropriate level. Matching soil to microclimate. Matching microclimate to crop.
On the warmest lowest terraces: coca leaf, medicinal herbs --- plants of the jungle lowlands, coaxed into surviving at altitude. In the middle zones: quinoa, amaranth. On the cooler upper rings: potatoes, corn. More than two hundred and fifty plant species cultivated in one extraordinary place. A single site that compressed the full ecological range of an empire into a set of concentric circles on a cold plateau in the mountains.
The name itself carries something of this. Moray comes from Quechua --- likely a contraction of muyu, meaning circle, and uray, meaning below. Circle of the below. But another tradition connects the name to Aymoray --- what the Inca called the month of the corn harvest. The month of abundance. The month of giving thanks.
A laboratory named for a harvest festival. I have always loved that detail. It tells you, more clearly than anything else, what kind of people these were.
I have stood in temples on every continent. I have watched priests in linen and priests in feathers and priests in silk perform their sacred duties with absolute conviction. I know what devotion looks like when it is formalized --- when it has robes and incense and designated hours and walls built to contain it.
What I saw at Moray was something different. Something I find, even now, difficult to put into words without feeling that the words are too small.
For the Inca, the sacred did not live in a separate building. It did not have its own day of the week or its own set of specialists who handled it so that everyone else didn't have to. The sacred was woven into everything --- into the earth underfoot, into the water moving through the irrigation channels, into the specific angle at which the morning sun struck a particular terrace at a particular time of year. The farmer kneeling in the soil was performing the same essential act as the priest standing before the altar. They were both, in their way, in conversation with something larger than themselves.
The name for the principle at the center of all of this was ayni. Reciprocity. The understanding that nothing is truly owned, that everything is borrowed, and that the correct response to receiving is to give back. Not as transaction --- not as payment --- but as a natural expression of being alive inside a living world.
Pachamama --- the Earth Mother --- was not an abstraction to the Inca. She was not a distant creator god who had set things in motion and stepped back. She was present. She was the soil warming under your hands. She was the water arriving through the channel your grandfather carved. She was the frost that could take your crop in a single night if you had not read the season carefully enough. To farm was to be in relationship with her. And Moray was, among other things, a place where that relationship was studied with extraordinary seriousness.
Think about what they were doing there. They were asking: what does this particular plant need in order to flourish? What temperature? What soil? What moisture? What light? They were not asking these questions abstractly --- they were building the answers into stone, level by level, terrace by terrace, so that the knowledge could be tested and refined and eventually carried back out into the empire, to farmers in a hundred different valleys and climate zones who needed to know how to feed their families and their communities.
That is science. But it is also prayer. Because the question underneath all the other questions --- the one that gave all that patient, precise, backbreaking work its meaning --- was this: how do we take care of what has been given to us?
And then there was the ceremony.
Every August, when the sun began its return and the new agricultural year prepared to turn, the communities around Moray gathered at the rim of those great circles for a ceremony called Wata Qallariy --- in Quechua, the beginning of the agricultural year. They came to give thanks for what the last cycle had provided. They came to ask for abundance in the one ahead. They came to stand together at the edge of what their ancestors had built and to remember, as a community, that the earth was not a resource to be managed. It was a partner to be honored.
I watched those gatherings across many generations. The faces changed. The clothing changed. The specific words of the prayers evolved, as prayers always do. But the posture never changed --- the gathering at the rim, the looking down into the circle, the sense of something owed and something hoped for, held together by the word that means both thank you and please.
Science, ceremony, and daily labor. Not three things. One thing. Seen from different angles on the same cold morning.
I want to tell you something about threads.
I have followed many of them across my long wandering life. I have watched ideas flare up in one place and travel --- carried in books, in ships, in the mouths of travelers, in the memories of refugees --- until they surface somewhere else, centuries later, barely recognizable but still alive. That is usually how it works. Ideas travel because people carry them. They transform in the carrying. They arrive somewhere new wearing different clothes.
Moray is not that kind of story.
What the Inca built on that plateau did not travel. It did not get carried in ships to Europe or copied into manuscripts or translated through a chain of scholars working in candlelit rooms. The Spanish arrived in 1533, and within a generation the empire was gone --- its roads still running, its terraces still standing, but the civilization that had made sense of them shattered beyond recovery. The knowledge of Moray did not flow outward into the world's intellectual tradition. It stayed where it was.
And yet the thread did not break.
Because the people who lived beside Moray --- the Quechua-speaking farming communities of the Chinchero plateau --- never left. They watched the empire fall. They endured the centuries of colonial rule that followed. They adapted, as people do, and survived, as people do. And they went on farming those terraces. Not as an act of resistance, not as cultural preservation in any self-conscious sense --- simply because the land was there and they knew how to work it, and their grandparents had worked it, and theirs before them.
The outside world did not rediscover Moray until 1932, when an American geographer flying over the plateau looked down and saw the circles and could not account for them. It was the same aerial expedition that spotted the Nazca Lines --- another set of marks made by Andean hands in the earth, waiting patiently to be noticed by people who had not been there to see them made. The academic theories about Moray's purpose --- the agricultural laboratory hypothesis --- were not formally proposed until 1975. Not until 1975 did the outside world begin to understand, in its own terms, what had been built there.
But the communities around Moray had always known. They didn't need a hypothesis. They had the knowledge itself, passed down in Quechua, held in the practices of planting and tending and giving thanks that their ancestors had carried forward through every disruption the centuries had brought. The Wata Qallariy ceremony --- the gathering at the rim every August to mark the beginning of the agricultural year --- never stopped. It was not revived. It continued.
I find that almost unbearably moving. Not because survival against the odds is unusual --- it isn't, people are remarkably tenacious --- but because of what survived. Not just a practice. Not just a ceremony. A way of understanding the relationship between human beings and the living world they inhabit. A conviction, encoded in stone and ritual and the Quechua language itself, that the earth is not a resource. That knowledge exists to be shared. That the correct response to abundance is gratitude, and the correct response to gratitude is care.
The Inca Empire lasted less than a century at its height. The terraces of Moray have stood for somewhere between five hundred and a thousand years, depending on which level you measure. And every August, people still gather at the rim.
That is what a golden thread looks like when it holds.I have been watching your world for a while now. Long enough to notice certain patterns. Long enough to see when a very old question comes back around wearing new clothes.
Here is the question that is back.
How do we take care of what has been given to us?
You hear it in the conversations about climate. About soil exhaustion and vanishing species and rivers that no longer reach the sea. About the slow, incremental damage done by centuries of treating the earth as a warehouse rather than a living partner. The conversations are urgent and necessary and I am glad they are happening. But I notice something missing from most of them. A dimension that the people of Moray would have found so obvious it wouldn't have needed a name.
The sacred dimension.
Your world has become very good at measuring what is wrong. The parts per million of carbon. The percentage of topsoil lost. The rate of species extinction. The data is real and the data matters. Science is doing its work. But data alone does not change how people feel about the earth. It does not tell them what they owe it. It does not give them the posture of ayni --- the deep, practiced, habitual sense that you are in a reciprocal relationship with the living world, that what you take must be returned, that the earth's abundance is not an entitlement but a gift that carries responsibility.
That posture has to come from somewhere else. It has to come from the part of a human being that science does not reach --- the part that gathers at the rim of a circle every August to give thanks for a harvest, that carries soil from a distant valley to give a struggling plant what it needs, that builds knowledge not to own it but to share it, because the point was never profit. The point was that everyone eats.
The Inca did not separate science from spirit. The careful observation of temperature and moisture and seasonal light was not in tension with the ceremony that honored Pachamama. They were expressions of the same underlying conviction --- that the earth is alive, that it deserves attention, and that attention paid with both the mind and the heart is more powerful than either alone.
I think about this when I hear the debates --- and there are so many debates --- between those who trust only data and those who trust only faith, as though these were the only two options available to a human being trying to understand the world. The terraces of Moray were built by people who did not recognize that choice. They studied the earth with extraordinary precision and they loved it with their whole civilization. Both. At the same time. For centuries.
And the knowledge they gathered was not locked away. It was not the property of an academy or a priesthood or a class of specialists who controlled access to it. It moved outward through the empire as a gift --- shared with farmers in every climate zone so that communities could feed themselves with dignity. The organizing question was not who profits from this knowledge but who needs it. That is a different civilization than the one most of us were born into. But it is not an impossible one.
The Wata Qallariy ceremony still happens every August at the rim of those circles. Quechua-speaking communities still gather there to give thanks and ask for abundance. The thread did not break. And I think there is something in that continuity that is more than historical curiosity --- something that the world, in its current urgent conversation about how to live on this earth without destroying it, genuinely needs to hear.
The Inca already answered the question. They answered it in stone and ceremony and a word --- ayni --- that means the earth gives to you and you give back, and the giving is not a transaction but a relationship, and the relationship is sacred, and the sacred is not separate from the practical but woven all the way through it.
That answer is still there. Still waiting at the rim.
I want to ask you something, and I want you to take it seriously.
What do you tend?
Not in the grand sense. Not your career or your legacy or the impression you make on the world. I mean the small things. The things you return to quietly, regularly, without an audience. The things you give your attention to not because anyone is watching but because something in you knows they need it.
A garden, maybe. A friendship you check on even when there is no particular reason to. A skill you practice in the early morning before the day makes its demands. A child you sit with. A patch of earth you have learned to read --- the way it holds water after rain, the angle of light it receives in late afternoon, the particular cold that comes off it before a frost.
The Inca farmers who worked the terraces of Moray were not remarkable people in the sense we usually mean. They were not rulers or priests or philosophers whose names were recorded. They were people who showed up, season after season, to a cold plateau at eleven thousand feet and paid close attention to how things grew. They carried soil from distant places to give their plants what they needed. They built stone walls that released heat slowly through cold nights to protect roots that couldn't protect themselves. They did this work with their hands and their knowledge and their prayers, and they did it not for themselves alone but for the twelve million people who would eat because of what was learned there.
That is an extraordinary life, lived without any of the markers we usually use to call a life extraordinary.
I think about the word ayni --- reciprocity --- and I wonder what it would mean to carry it as a practice rather than just an idea. Not as a political position or a philosophical stance but as something lived. A habitual returning. A regular giving back. A quiet conviction that the world has been generous to you and that generosity deserves a response.
You don't need a high plateau in the Andes to practice that. You need whatever is in front of you. Whatever has been given to your care. Whatever is waiting, quietly, for you to pay attention.
The farmers of Moray knew something that is easy to forget in a world that moves very fast and measures very carefully and sometimes forgets to be grateful. They knew that tending is itself a form of love. That showing up, season after season, to something you did not create and cannot fully control, and giving it your best knowledge and your honest care --- that is not a small thing.
It is, in fact, the thing.
I have one more thing to show you before we part today.
Every August, when the sun begins its return over the Sacred Valley and the new agricultural year prepares to turn, the Quechua-speaking communities of the Chinchero plateau gather at the rim of those great circles. They have been doing this for longer than anyone can precisely say. The Spanish came and the empire fell and the centuries rolled over this plateau like weather, and still, every August, the people come. They give thanks for what the last cycle provided. They ask for abundance in the one ahead. They stand together at the edge of what their ancestors built and they remember, out loud, in Quechua, that the earth is a partner and not a possession, and that the correct response to receiving is to give back.
Wata Qallariy. The beginning of the agricultural year. It is not a reconstruction. It is not a revival. It simply never stopped.
I have stood at that rim many times. I have watched the morning light move down the terraces level by level, warming each stone in turn, the way it has always done, the way it will do long after all of us are gone. And I find myself thinking, every time, that this is what a civilization looks like when it gets something fundamentally right. Not perfect --- no civilization is perfect --- but right about the thing that matters most. Right about the relationship between human beings and the living world that holds them.
The circles are still there. The ceremony is still there. The word ayni is still there, in the mouths of people who have carried it across centuries of hardship and loss and quiet persistence.
The thread held. It is still holding. And I think, wherever you are, in whatever landscape you call home, you already know something of what it means. You have felt it --- in a garden, in a season, in the particular satisfaction of returning something you borrowed and finding the world a little better for the exchange.
That feeling has a name. The Inca had it first.
Next time, I want to take you somewhere very different --- to the streets of nineteenth century New York, to a young man named Isaac Hecker who pushed a baker's cart as a boy, wandered into the company of some of the most restless minds in America, and ended up in Rome arguing with the Pope about the future of faith in a democracy. He was looking for something too. And what he found --- and what it cost him, and what he built from the ruins of what was taken away --- is a story I have been wanting to tell you for a long time.
Until then, tend what is yours. With knowledge. With care. With gratitude.
Much love. I am, Harmonia.
