Nadi

Nadi in Sanskrit means river. In yoga, the word applies specifically to the subtle currents of energy one may experience within the body — not the circulatory system, not the nervous system, but a third architecture, felt rather than measured, that organises the body’s inner life along channels as precise as veins. In the throat and the pelvis there is a confluence of three rivers: ida, pingala, and sushumna — the lunar, the solar, and the central. These internal rivers are experiential, embodied. They are not metaphors for information. They are the body’s own hydrography, as real to the practitioner as the bloodstream is to the surgeon.

The portrait format of this painting is itself a nadi. In contrast to the vast, horizontal endlessness of the landscape format, the portrait focalises us in relation to the spine of space. It is the landscape finding its feet — the earth standing upright, acquiring a vertical axis, a throat, a pelvis. The iron rivers that run through this work no longer flow laterally, as they do in the aerial landscape paintings. Here they descend. They find their channel. The beleaguered earth, thrown upright, becomes a body.

The iron is gathered from landscapes throughout the world: the slopes of Snæfellsjökull, the 700,000-year-old glacier-capped volcano in Iceland that Jules Verne chose as the entrance to the centre of the Earth; the Atlas Mountains of Morocco, where Berber miners have extracted iron ore since antiquity. These are not interchangeable sources. Each landscape deposits a different iron into the pigment — different oxidation states, different mineral companions, different geological memories. The iron from Snæfellsjökull carries the memory of oceanic rift; the iron from the Atlas carries the memory of the African plate’s collision with Europe. When these pigments are thrown, disgorged, emanated onto cotton paper, they do not illustrate landscape. They *are* landscape — compressed, transported, and released into a new field.

Iron is the element of conduction. Every atom of it was forged in the core of a star that died — the last element a star can produce by fusion before it collapses. It conducts electricity. It conducts heat. It generates the magnetic field that shields the biosphere. And it conducts the subtle currents of the earth’s own body: the liquid iron alloy churning in the outer core, four thousand kilometres below the surface, producing the geodynamo that orients every compass, every migrating bird, every magnetotactic bacterium swimming in the dark.

In 1858, the Transatlantic cable was installed on the seabed, connecting Europe to North America. The cable was encased in an iron sheath — intended only to strengthen it. But iron, as a conductor, interfered with the propagation of electromagnetic fields, increasing the capacitance of the line. The sheath meant to insulate instead conducted. The boundary meant to contain instead transmitted. This is why today most power lines are suspended in air rather than buried in earth — the planet’s iron, like a vast battery, generates electrical fields in the very ground where we dwell. The insulating skin of iron summoned what it was designed to prevent: a non-dual state of energy, where the current passed ecstatically beyond its sheath.

This is the principle I follow in the studio. The iron pigment is not applied as surface. It is applied as conductor — a substance that cannot help but transmit what passes through it. The drawing becomes a cable. The paper becomes a seabed. The current that moves through the work is not depicted but conducted, and the iron — remembering fire, remembering pressure, remembering the stellar furnace where it was forged — cannot be inert. It carries what it has always carried. It conducts.

On the ocean floor, close to the tectonic spreadings where plates pull apart and the earth’s interior is exposed to seawater, fresh mantle rocks lie bare. Water drips down beneath the sea floor, deep into the blazing currents of iron. There it reacts with olivine to form serpentinite — a green, veined, sinuous mineral whose name derives from the serpent. The reaction produces intense heat and hydrogen gas. And it is from the chemical remainder of this process — in the superheated vents where serpentinite meets water — that life began. Not from sunlight. Not from the surface. From the depths, from iron, from the serpentine reaction in the dark.

The metabolism that arose at those vents was chemical, not photosynthetic. It did not depend on the sun. It depended on the flux of electrons between minerals — a current that we find, today, inside the mitochondria of our cells, the ancient bacterial engines that still run on iron-sulphur chemistry. This flux precedes our genetic code. It precedes DNA. It precedes the distinction between plant and animal. It is older than the categories we use to organise life, because it is the current from which the categories emerged.

The serpentinite is the geological nadi. The ocean ridge is the body’s spine. The vent is the confluence — the place where three rivers meet: mineral, water, heat. And what rises from that confluence is not a substance but a process: the transformation of potential into life, the passage of current through matter, the moment where chemistry becomes metabolism and the dead begins to breathe.

In yoga, the central channel — sushumna — must remain empty for the current to rise. It is a riverbed, not a river. The energy does not flow through a full channel. It flows through a cleared one. The nadis must be purified — *nadi shodhana*, the cleansing breath, the alternation of ida and pingala until sushumna opens — before the dormant force at the base of the spine can ascend.

The same principle governs the painting. The iron is thrown onto the paper with force — disgorged, not placed. But the composition is not the iron. The composition is what the iron *reveals*: the channels between the rivers of pigment, the clearings in the dark field, the empty passages where the current can move. The painting, like the body in practice, is a system of nadis. What matters is not where the pigment lands but where it doesn’t — the bare paper, the exposed cotton, the white spine running through the iron field like sushumna through the body’s dark interior.

It is the movement that creates the form. And the form is not the iron, not the pigment, not the mountain’s memory or the star’s residue. The form is the clearing — the river that runs through everything, visible only where the ground has been opened, audible only where the noise has been stilled. A form disgorged by the crack that is in everything.
