Ibn Arabi and the Mundus Imaginalis: The Medieval Discovery That Inner and Outer Are One

Something happens when your life stops making sense. The job, the marriage, the self you built carefully over twenty years — it all goes quiet, or falls apart, and you are left with a strange feeling that the world outside no longer matches anything you can find inside. You are not depressed, exactly. You are just — between. A twelfth-century philosopher from Andalusia spent his entire life trying to describe that territory. He called it a world between worlds. He thought it was the most important place a human being could learn to read.

Murcia, 1165: A Mind Formed at the Edge of Two Worlds

Ibn Arabi was born in Murcia, in what is now southern Spain, on 28 July 1165. The city sat at the intersection of Islamic, Jewish, and Christian civilisation. It was a place where three worlds of thought met and argued over the same streets.

His full name was Muhyi al-Din Muhammad ibn Ali ibn Muhammad ibn Arabi al-Hatimi al-Ta'i. Scholars call him al-Shaykh al-Akbar — the Greatest Master. He earned the title not through self-promotion but through sheer scale. By his death in Damascus in 1240, he had written more than 300 works. His two major texts — the Futuhat al-Makkiyya (The Meccan Openings) and the Fusus al-Hikam (The Bezels of Wisdom) — together run to millions of words.

He was not a hermit. He studied with scholars in Seville, travelled across North Africa and the Arabian Peninsula, and spent years in Mecca, Anatolia, and finally Syria. His thinking was shaped by everything he encountered: Greek philosophy (Aristotle and Plotinus especially), the Quran and its interpretive traditions, Sufi practice, and a strand of Islamic philosophy that took seriously the question of how the human mind knows anything at all.

That question — how do we know? — is where his most lasting contribution began.

The Three Worlds: Where Imagination Sits Between Matter and Spirit

Medieval Islamic philosophy inherited a problem from ancient Greece. Aristotle had said that knowledge comes through the senses — you touch, see, hear, and your mind builds a picture of the world. Plato had said the opposite: the real world is not what the senses show you but an invisible realm of pure forms or ideas, and the senses are almost a distraction. Most thinkers picked a side.

Ibn Arabi refused. He said both were partly right and both were missing something. Between the world of pure matter (what the senses touch) and the world of pure spirit (what reason and revelation describe), there is a third territory. He called it the 'alam al-mithal — the world of image, or the imaginal world.

The French philosopher Henry Corbin, who spent decades translating and interpreting Ibn Arabi, coined the Latin phrase mundus imaginalis to describe it. Corbin was precise about the translation for a reason. He did not want the word imaginary, because that word in modern English means "made up" or "not real." The imaginal world, for Ibn Arabi, is absolutely real. It is simply a different kind of real from the rock you can stub your toe on.

The imaginal world, in this framework, is where symbols live. It is where dreams happen. It is where a vision carries information that cannot be reduced to either a physical sensation or a dry logical argument. It sits exactly between those two registers.

For Ibn Arabi, this was not poetry. It was geography. He meant it literally: there is a world there, it has structure, and the faculty of imagination is the organ we use to perceive it — the way the eye perceives light.

Himma: The Imagination That Creates, Not Just Copies

Most people think of imagination as something passive. You picture something that already exists, or you invent something that does not. Either way, the imagination seems to be describing reality, not participating in it.

Ibn Arabi saw it completely differently. He used the Arabic term himma — often translated as "creative power" or "concentrated spiritual energy" — to describe the active capacity of the imagination. Himma is the imagination at full force. It is not just seeing a mental image. It is generating something real.

This sounds strange. It sounds like magical thinking. But Ibn Arabi was careful. He was not saying that if you imagine a cup of tea, a cup of tea appears on your desk. He was saying something more specific: that the act of genuine imagination — deep, sustained, directed attention on an inner image — creates in the imaginal world a form that is real at that level of being. It is real in the way a dream is real while you are in it. Not the same kind of real as a rock, but not nothing, either.

Corbin spent years making this distinction. In Alone with the Alone (1969), he traced how Ibn Arabi's concept of himma anticipates what we now call active imagination — the practice Carl Jung developed in the early twentieth century, where a person consciously engages with the figures and images arising from the unconscious mind.

Jung almost certainly did not read Ibn Arabi directly. He arrived at a parallel idea through a completely different route: clinical observation of his patients, his own breakdown between 1913 and 1917, and his immersion in medieval European alchemy. The convergence is striking precisely because the two thinkers were not in contact.

If you want to understand how Jung developed his own version of this practice, the article on active imagination as a psychological technique picks up where this one leaves off.

The Human Being as Barzakh: Living at the Threshold

One of Ibn Arabi's most striking ideas is that the human being is not just a creature who occasionally visits the imaginal world. The human being is, by nature, a threshold creature. The Arabic term he uses is barzakh — an isthmus, a narrow strip of land between two bodies of water. We are the isthmus between matter and spirit.

This is not flattery. It is a description of a job.

Ibn Arabi's argument runs like this. The divine reality — what he calls al-Haqq, the Real — cannot know itself directly, because it is infinite and self-contained. It needs a mirror. The human being is that mirror. But the mirror only works if it is positioned at the boundary — between the visible world and the invisible one. A mirror that sits entirely inside one realm or the other shows nothing.

So the human task, in his framework, is not to choose between matter and spirit, or between the rational and the emotional, or between the outer life and the inner one. The task is to stand at the place where they meet and let both sides become visible through you.

This has immediate consequences for how we understand identity change. If you are in the middle of a divorce, a burnout, or a faith collapse — the kind of experience where the person you were no longer fits — Ibn Arabi would say you are at the barzakh. The old image has dissolved. The new one has not yet formed. The discomfort of that position is not a mistake. It is the exact condition under which a human being functions at full capacity.

The alchemists of medieval Islam and Europe had a name for this stage of dissolution. Jung borrowed it: nigredo, the blackening, the collapse before the new form arrives. If you are in it now, the article on burnout as nigredo maps the same territory from a psychological angle.

What Ibn Arabi Meant by "Inner and Outer Are One"

The title of this article makes a claim that can sound like a spiritual slogan. It is not. Ibn Arabi's argument for the unity of inner and outer is a specific philosophical position with a precise structure.

He begins with the idea of tajalli — divine self-disclosure. God, in his framework, constantly discloses the divine reality through the forms of the world. Every created thing is, in some sense, a name of God made visible. But the disclosure does not happen once, like a painting finished and hung on a wall. It happens continuously. At every moment, a new form arises, shows itself, and passes.

The human being participates in this process through imagination. When you genuinely imagine something — when you hold an inner image with full attention — you are not just passively receiving an impression of the outer world. You are actively participating in the same process of disclosure that produces the outer world. The inner and the outer are two faces of the same movement.

This is why Ibn Arabi calls the imagination al-khayal — and why he says it is the most important human faculty. Not because it produces pleasant fantasies, but because it is the place where the human being touches the process that generates reality itself.

Corbin is careful to say that this is not idealism in the Western philosophical sense — it is not the claim that the world exists only in your mind. Ibn Arabi held that the outer world is real. He is saying something different: that the inner and the outer are not two separate territories with a wall between them. They are continuous. The imaginal world is the membrane where they become one.

For someone in the middle of identity change, this reframes what the strange inner images mean — the recurring dream, the figure that keeps appearing in half-sleep, the symbol that seems to follow you. These are not noise. In Ibn Arabi's framework, they are transmissions from the junction point between what you have been and what you are becoming.

Ibn Arabi in the History of Alchemy

Islamic civilisation in the twelfth century was the primary custodian of the alchemical tradition. The word alchemy itself comes from Arabic — al-kimiya — and the Arabic tradition had absorbed the Greek texts (particularly the Hermetic corpus and the works attributed to Jabir ibn Hayyan) and extended them substantially.

Ibn Arabi was not primarily an alchemist in the laboratory sense. He did not write recipes for turning lead into gold. But his philosophical framework was deeply alchemical in its structure. The movement from matter to spirit and back — the idea that the two are not opposed but interpenetrating — is the central image of both the alchemical tradition and Ibn Arabi's cosmology.

The Emerald Tablet, the foundational text of Western alchemy attributed to Hermes Trismegistus, contains the phrase: "That which is below is as that which is above, and that which is above is as that which is below." Ibn Arabi's three-world model is one of the most sophisticated medieval attempts to give that phrase precise meaning. If the Emerald Tablet interests you as a document, the article on the Emerald Tablet and human transformation traces its history directly.

The transmission of these ideas from the Islamic world into European alchemy and eventually into Jung's psychology is one of the more underappreciated stories in intellectual history. It moved through specific channels: through the translation movement of the twelfth and thirteenth centuries in Toledo and Palermo, where Arabic texts were rendered into Latin; through the influence of Islamic philosophers like Avicenna and Averroes on European universities; and through the Sufi mystical tradition that preserved Ibn Arabi's work across centuries when it was politically dangerous to reproduce it.

Why This Matters at 2am in 2026

You did not search for "Ibn Arabi" or "mundus imaginalis." You probably searched for something much closer to the ground: why you feel hollow, why you cannot recognise yourself in the mirror you used to trust, why the life you built so carefully feels like someone else's.

Ibn Arabi's framework does not fix that. Nothing does, quickly. But it offers something specific: a map of the territory you are actually in.

The territory has a name. It is the barzakh — the threshold, the isthmus, the between-space. The person you were has dissolved. The person you are becoming has not yet become concrete. You are in the imaginal world, whether you call it that or not. The images arising from that place — the strange dreams, the sudden clarity at 3am, the sense that something old is ending — are not symptoms of malfunction. They are the process working.

Ibn Arabi would say: pay attention to them. Not with analysis. Not with the part of your mind that makes spreadsheets and assigns blame. With the older, quieter faculty he called imagination — the one that can hold a symbol without immediately converting it into an action plan.

This is what the alchemists meant when they said the work begins in the black stage — the nigredo — and does not end there. The dissolution is not the problem. It is the beginning of the process. The imaginal world is where the new form starts to take shape, before it is solid enough to be visible in ordinary life.

Eight hundred years later, in a different language and a completely different cultural context, Carl Jung described exactly the same thing. He called it the transcendent function: the capacity of the psyche (the whole self, conscious and unconscious) to generate a new position that neither the old self nor the crisis alone could have produced. The imaginal — the mundus imaginalis — is where that function operates.

Frequently Asked Questions

What is the mundus imaginalis?

The mundus imaginalis is a term coined by the French philosopher Henry Corbin to translate Ibn Arabi's concept of the 'alam al-mithal — a middle world between pure matter and pure spirit. It is not fantasy or make-believe. It is the domain where symbols, dreams, and visions carry real information about reality. Ibn Arabi treated it as a third territory that most people never learn to read.

Who was Ibn Arabi and why does he matter today?

Ibn Arabi was a twelfth-century Andalusian mystic and philosopher born in Murcia in 1165. He wrote over 300 works, including the Fusus al-Hikam and the Futuhat al-Makkiyya. He matters today because he developed a detailed account of how imagination mediates between the self and reality — an insight that modern psychology, particularly Carl Jung's work on the unconscious, later rediscovered independently.

How does the mundus imaginalis connect to personal transformation?

Ibn Arabi argued that the imagination is the primary place where a person changes. When you are in the middle of a real identity shift — a burnout, a divorce, a faith collapse — the images that rise up in dreams or quiet reflection are not escapes. They are diagnostics. They show you what is dissolving and what is trying to form. Working with them, rather than suppressing them, is what transformation actually looks like from the inside.

What is the connection between Ibn Arabi and Carl Jung?

Jung and Ibn Arabi arrived at similar conclusions eight centuries apart. Both argued that imagination is not mere fantasy but a real cognitive faculty capable of producing genuine insight. Jung called it active imagination and the transcendent function. Ibn Arabi called it the creative imagination, or himma. Henry Corbin, who studied both thinkers, was the first to make this parallel explicit and wrote extensively about it in Alone with the Alone.

Is Ibn Arabi's philosophy compatible with science?

Ibn Arabi was not a neuroscientist and made no such claims. But modern research on the default mode network — the brain system most active during imagination, self-reflection, and dreaming — suggests that inner imagery and outer perception share much of the same neural machinery. The brain does not cleanly separate imagined and real experience. This does not prove Ibn Arabi right, but it makes his central intuition harder to dismiss.
