Autoimmunity is a heart that is breaking.
Autoimmune signals are not an error. They are the body reorganizing around what it cannot digest. An essay on the depletion of ojas, the vagal channel, and the metabolism of a world in pain.
Autoimmunity is a heart that is breaking. Not metaphorically. Not in the way we say heartbreak when we mean sadness, or heartache when we mean longing. The heart: the physical organ, the muscular fist behind your sternum. It is the reservoir of something the body cannot function without, and when that reservoir cracks, the body loses its capacity to recognize itself.
In Sanskrit, the heart is called hṛdaya. Ayurveda describes it as the home of ojas. Ojas is the final distillation of everything the body digests. Not just food. Everything.
Every sensation, every encounter, every piece of information you take in gets processed through a sequence of tissue layers, each one refining the substance further, and what arrives at the end of that long metabolic cascade is ojas: a small, luminous, unctuous essence that the classical texts describe as honey-coloured, sweet, and cool. Eight drops of it live in the heart. These never move; they are the anchor.
The rest circulates. It coats your tissues. It lines your vessels. It is what allows your immune system to scan your body and say: this is me. This is mine. This belongs. Ojas is not a defense system, it is a marker of recognition. It is the substance by which the body knows itself.
When ojas is depleted, the body’s skill for self-knowledge is lessened. The immune system listens to the tissues and hears a language it no longer speaks. It encounters its own marrow, its own nervous tissue, saturated with material that was never fully digested — residue from experiences the system couldn’t metabolize. The inflammation begins. The joints swell. The skin erupts. The fatigue descends like a door closing.
This is autoimmunity. The body attempts to purify what it can no longer recognize, working under duress. A desperate, burning effort to clear the archive.
And ojas, the substance that would prevent this, the substance that holds the self together — lives in the heart.

So when I say autoimmunity is a heart that is breaking, I mean the vessel is cracked. The reservoir is leaking. The place where the body stores its most refined capacity for self-recognition has been damaged, and what damages it is grief.
The classical texts are explicit. Charaka, one of the foundational authors of Ayurvedic medicine, writing over two thousand years ago, lists the causes of ojas depletion: excessive exertion, prolonged hunger, harsh exposure to the elements, intense worry, fear, anger, and shoka. Grief. He also names vishada, despair, as the single most potent aggravator of disease.
Grief depletes ojas through a precise mechanism. When you grieve, the body’s principle of movement — vata, which governs everything that shifts, dries, contracts, and cools — surges. It moves like a cold wind across the digestive fire. The fire gutters. Digestion falters. Instead of producing the refined, nourishing substance that eventually becomes ojas, the system produces ama: a heavy, sticky, toxic residue. The incomplete product of incomplete processing. And at the same time, that same cold wind dries out the existing ojas. The reserves evaporate. The container empties from both ends, production stops, and stores deplete.
You know this in your body. You have felt what grief does. The heaviness. The fog. The sense that your skin is thinner, that sounds are louder, that you cannot tolerate what you could tolerate before. That you are porous where you were once intact.

Hold that. And juggle with this:
The heart is not just a pump. It contains approximately forty thousand sensory neurons — its own intrinsic nervous system. It sends more information up to the brain than the brain sends down to it.
The vagus nerve is the longest nerve in the body. It runs from the brainstem through the throat, past the heart, into the gut. It is not a wire. It is a living tissue, a wet rope of fibres, and eighty-five to ninety percent of those fibres run upward. From the viscera to the brain. The heart is not receiving orders. It is issuing reports. It reads the blood, the rhythm, the hormonal tide, and it tells the brain what is happening in the body.
When the parasympathetic system is doing its work, it holds inflammation in check through regulation. The way a riverbank holds a river. The channel keeps the water where it can move, where it can nourish. When the channel erodes, the water goes everywhere. The fields flood. Nothing is reached. Everything is saturated.
This is what happens when grief overwhelms the vagal channel. The inflammatory signalling that the parasympathetic system normally regulates spills into every tissue. The cytokines — the body’s alarm signals — rise and stay risen. The immune cells, bathed in distress signals, begin to read the body’s own tissue as debris to be cleared.
There is a cardiac event called Takotsubo — named for the Japanese octopus trap, because of the shape the left ventricle takes when it balloons under acute emotional shock. It happens after the death of a spouse. After the death of a child. After witnessing something the heart cannot metabolize. The catecholamines surge. The vagal tone collapses. And in the heart itself — in the actual muscle — inflammatory cells flood the tissue. The heart’s own immune environment destabilizes. The organ that holds ojas becomes the site of its unravelling.
Grief is not a psychological event with physical side effects. It is a physical event. It happens in the flesh of the heart, the lining of the gut, and the fibres of the vagus. It has a distinct biological signature — not the same as depression, not the same as post-traumatic stress. Complicated grief, the kind that does not resolve, that sits in the body like a stone the system cannot pass, produces its own specific pattern of immune reorganization. The body does not merely “react” to grief. It reorganizes around it. It takes the shape of what it cannot digest.
The heart reads the blood, the hormonal tide, the vagal signals ascending from the gut. It is in constant contact with the interior of the body. Through the vagal afferents, through the breath, through the skin, the heart reaches into the space that surrounds you.
And what does it encounter there?
I don’t need to explain this. You already know the world is in pain. The rivers are poisoned, the forests are burning. The political structures meant to protect collective life are cannibalizing themselves. The creatures are dying, the ice is gone; the air carries particulate matter into the deep tissue of the lungs and from there into the blood. Microplastics are in every human placenta ever tested. The soil, stripped of its microbial intelligence by decades of industrial agriculture, produces food that fills the stomach and starves the cells.
You feel all this. It is not an idea. You feel it as a weight in your body, a visceral fog. As something saturating.
Children who lose a parent, who experience attachment disruption, the grief-shaped wound at the foundation of self, carry measurably altered immune landscapes into adulthood. Not because of the other adversities that often accompany loss, but because of the loss itself. The grief sensitizes the immune terrain. The inflammatory baseline shifts. The capacity for self-recognition narrows. And decades later, autoimmune conditions emerge at higher rates than in those who experienced other forms of adversity. The loss itself is the sensitizing event. The grief is the substance that reshapes the immunological soil.
The heart feels it too. The heart is in constant contact with the suffering of the environment it inhabits. It is not buffered from the world. It is open to it. It was designed to be open to it.
Here is what no one has measured: the inflammatory markers of farmers watching their land die. The vagal tone of Indigenous communities watching their rivers turn. The immune self-tolerance of populations living inside environmental collapse. Ecological grief — the term now exists, the psychological descriptions proliferate, the scales are being adapted across cultures — but no one has drawn blood. No one has asked the body what it knows.
Not because the question is unanswerable. Because the question has not been asked in a form that crosses the disciplinary walls. The body is not waiting for these conversations to happen.
If you are living with an autoimmune condition, you have likely been told that your immune system is confused. That it is overreacting. That it has made a mistake.
Your body has not made a mistake. Your body is responding to the weight of what it has received. The grief you carry is not neurotic. It is not a failure of positive thinking. It is the felt registration of real damage to the real world, processed through a real organ, along a real nerve, into a real immune landscape that reorganizes around what it cannot metabolize.
The grief is real. The body is real. The vessel is not confused. The cargo is real, and the seas are rough. The relationship between them is direct, physical, and ancient.
The first gesture of navigation is to stop treating the body’s signal as noise. To recognize that the wounded heart is telling the truth, and that the truth has weight, and that the weight is what the vessel is carrying.
The heart is grieving the world. The grieving heart is no fit container for ojas. And from that cracked vessel, the conditions of autoimmunity emerge — not as error, but as echo. The body registers the state of the earth it inhabits. Deha to desha. The body to the land.
