The Red Book: Jung's Descent into the Unconscious

In 1913, Carl Jung was 38 years old, professionally successful, and quietly falling apart. His friendship with Sigmund Freud had just broken down. He was having visions he couldn't explain. Figures appeared in his mind — insistent, strange, not quite like dreams. Most people, in that position, would have suppressed what was happening and carried on. Jung did the opposite. He wrote it all down. Then he painted it. Then he bound it in red leather. What came out of that decision changed psychology permanently.

The Crisis That Started It All

The break with Freud in 1912 and 1913 was not just a professional disagreement. It was the collapse of a relationship Jung had built his career around. Freud had been mentor, father figure, and collaborator. When they parted — over fundamental differences about the nature of the unconscious — Jung lost his footing. He resigned as president of the International Psychoanalytic Association. He stopped writing academic papers. He later said he did not know who he was without that framework.

Then the visions began. In October 1913, Jung was traveling on a train through Switzerland when a waking vision flooded his mind: a vast wave covering northern Europe, turning the land to rubble, the water running red. It lasted roughly an hour. Two weeks later it came again, stronger. Then in August 1914, the First World War began. He had been seeing its shape before anyone else named it.

That shook him deeply. He did not claim to have predicted the war. He understood the visions as something else — as images rising from a layer of the mind that was not his alone. This was the beginning of his concept of the collective unconscious (the idea that beneath personal memory lies a shared psychological inheritance, common to all humans). He would spend the next sixteen years working out what he meant.

He began a journal. Then he transcribed that journal into a large folio manuscript, calligraphed by hand in Gothic script, illustrated with paintings he made himself. He called it Liber Novus — Latin for "New Book." The bound red-leather volume that housed it became known simply as the Red Book. He worked on it from roughly 1914 to 1930. He never published it. It stayed locked in a family safe until 2009, forty-eight years after his death.

What Is Actually In The Red Book

Norton published the first complete facsimile edition in 2009, edited by Jungian scholar Sonu Shamdasani. The volume weighs nearly nine pounds, about four kilograms. At full size, each page is roughly the dimensions of a medieval illuminated manuscript — which is not accidental. Jung was consciously borrowing that visual language.

The text inside has two main parts. The first is called Liber Primus and Liber Secundus together — a narrative account of Jung's deliberate inner journeys during the period of crisis. The second, called Scrutinies, is more reflective, less visionary. It is him trying to understand what the first part meant.

What he describes in the narrative sections is methodical, not mystical. He would sit, close his eyes, allow an image or a feeling to form, and then consciously engage with whatever appeared. He called this active imagination — a technique where you let the unconscious produce an image and then treat it as real enough to talk to, without directing what happens next. The Red Book records those conversations in dramatic form, like a strange one-man play.

Figures appear to him. Elijah, the biblical prophet — stern, old, quiet. A beautiful young woman named Salome, blind. A serpent. Later, a figure he calls Philemon — a winged old man with the horns of a bull who becomes his primary inner guide. Jung wrote that Philemon said things he had not thought himself, answered questions he hadn't fully formed, and seemed genuinely other. He was clear that Philemon was not real in any literal sense. He was equally clear that the conversations were not nothing.

This is the part many readers find hardest to hold. Jung was not claiming Philemon existed outside his mind. He was observing, as a scientist, that the mind contains material that does not feel like self — that some contents of the psyche seem autonomous (meaning they act on their own, without you choosing them). This observation, made under extreme personal conditions, became the empirical foundation of his theory of archetypes (universal patterns stored in the unconscious that take on particular forms and seem to behave with their own logic). You can read more about how those inner figures divide by gender in our article on anima and animus in Jung's psychology.

The paintings matter as much as the text. Jung painted his visions directly — mandalas (circular, symmetrical images he later identified as symbols of psychic wholeness), landscapes that don't quite follow physical laws, faces of the figures he met. Some are crude and urgent. Some are meticulous. Together they form a visual record of where he was going, and what he found.

Why He Kept It Secret for So Long

Jung did not lock the Red Book away because he was ashamed of it. He said, at various points, that he kept it private because it was unfinished, because it was too personal, and because he feared how it would be received. He had already been dismissed as mystical by some colleagues after his 1912 book Symbols of Transformation. Showing the world a hand-painted manuscript full of visions and inner demons would not have helped his standing.

But there is a deeper reason. Jung came to believe the Red Book was the source — the raw material from which everything else he wrote was distilled. Publishing it before the distillation was complete would, he thought, have been like handing someone an unprocessed ore and asking them to understand a finished metal. He wrote this in a note at the end of the manuscript:

After Jung died in 1961, the manuscript passed to his heirs, who were protective of it. His family was concerned about how it would be interpreted — that the visions would be used to pathologise him, or to strip his psychology of intellectual credibility. It took decades of negotiation by Shamdasani, a historian of psychology at University College London, to secure permission for publication. The 2009 Norton edition included Shamdasani's 200-page introduction, which remains the most rigorous scholarly account of the text's origins and context.

The publication was a cultural event. It appeared on the cover of the New York Times Magazine. It sold out repeatedly. Something about a brilliant man's private descent into darkness — kept secret for a century, then released — hit a nerve that no one had predicted.

What Jung Found, and What It Produced

The practical output of the Red Book period is almost everything Jung is known for. Not in finished form — but in first form, raw and undeveloped. The key concepts all appear there before they appear in his published writings.

The shadow — the parts of yourself you've rejected or never fully acknowledged — appears in the Red Book as an actual figure Jung meets and has to reckon with. It is not yet named "the shadow." But the encounter is described in enough detail that you can see exactly what he later meant by the term. Our article on the collective shadow traces how he extended this idea beyond the individual into society.

The concept of individuation — the long process of becoming more fully yourself, integrating the parts you've split off — appears as the Red Book's central narrative arc. Jung goes down, meets figures, has arguments with them, comes back changed. He does this again and again. That pattern became the template for his clinical method and his theory of psychological development.

The Self — Jung's term for the organising centre of the whole psyche, not just the conscious mind — appears in the Red Book as a figure of wholeness he calls Atmavictu (breath of life) and later simply encounters as the mandala, the circular image of completeness. He began painting mandalas daily during this period and noticed that on days of particular distress, the mandalas were asymmetrical. On calmer days they were balanced. He concluded they were measuring something real about his internal state.

The science block below is important here, because it addresses a real question: is any of this testable, or is it just one man's private mythology?

Active imagination — the technique Jung developed precisely during the Red Book period — is now the subject of modest but serious clinical research. Cwik (2011), in the Journal of Analytical Psychology, discusses reverie and active imagination as clinical practice. It is a theoretical and clinical paper, not an outcome study, and reports no symptom-reduction findings. The evidence base is small. The methodology varies. But the technique is no longer treated as purely speculative in the clinical literature.

Reading the Red Book When You Are Already in the Dark

The Red Book is a demanding text. It is deliberately archaic in style, written in a kind of heightened, prophetic prose that can feel alienating if you approach it expecting clarity. Shamdasani's 2009 introduction helps enormously. So does reading alongside Jung's more accessible autobiography, Memories, Dreams, Reflections, which gives the personal context in plain language.

But the harder question is not how to read it. It is why it still matters to someone who is not a therapist, not a historian, and not a student of Jung — someone who is just trying to understand what is happening to them right now.

The answer is this: the Red Book is the most detailed record we have of what happens when a person chooses to face their own interior honestly, rather than manage it. Jung was not trying to feel better. He was trying to understand. He made that choice at personal cost — to his reputation, his certainty, his professional standing. And he documented every step.

That is rare. Most people who fall apart do not take notes. Most people who lose the story they were living do not pause to write down what they see in the dark. Jung did. And what he found was not destruction. It was the rough material of a larger self.

This maps closely onto what alchemists called the nigredo — the black phase, the stage of dissolution, where everything you thought you were breaks down into something unrecognisable. We have written about that phase in depth in burnout and the nigredo. Jung knew the alchemical literature well, and he recognised in it an external metaphor for exactly what the Red Book had described internally. His engagement with alchemy shaped the second half of his career, producing works like Psychology and Alchemy (1944) that remain foundational in both fields.

The Red Book matters because it is evidence. Evidence that a serious person — a physician, a scientist, a man who had every professional reason to suppress what was happening — looked at his own dissolution and concluded that the images rising from it were worth attending to. Not acting on blindly. Not worshipping. Attending to. Sitting with. Writing down.

If you are in the middle of something that has no name yet — a divorce that makes sense on paper but feels like amputation, a career you built correctly and now cannot stand to walk into, a faith that simply stopped holding — the Red Book offers something more honest than comfort. It offers the testimony of someone who stayed in the room with the hardest material his mind could produce, and came out the other side with enough to build something real.

He was not the same person who went in. That is the point. Individuation is not recovery. It is not a return to the person you were before things broke. It is the slow emergence of someone wider — someone who contains the break as part of their structure, the way scar tissue contains the memory of a wound while being stronger than the original skin.

For a way to begin working with this material directly, rather than just understanding it conceptually, see our article on Jung's active imagination technique — the practice the Red Book gave us.

Frequently Asked Questions

What is Jung's Red Book?

The Red Book is a large, hand-calligraphed manuscript Carl Jung worked on between roughly 1914 and 1930. It records the visions and inner dialogues he deliberately entered during a period of personal crisis. He called the work Liber Novus, meaning "New Book." Norton published the first complete edition in 2009, almost a century after Jung began it.

Why did Jung have a breakdown before writing the Red Book?

Jung did not have a clinical breakdown in the standard sense. He experienced what he later called a confrontation with the unconscious — a period of intense, destabilising visions and emotional upheaval following his public split from Freud in 1913. He chose to face those visions rather than suppress them. The Red Book is the record of that deliberate confrontation.

What is active imagination, and how does it relate to the Red Book?

Active imagination is a technique Jung developed during the Red Book period. You enter a relaxed state, allow an image or figure from a dream or fantasy to appear in your mind, then consciously engage with it — asking questions, listening to answers — without directing the outcome. The Red Book contains Jung's first and most extended use of this method, with figures like Philemon and Elijah.

Was Jung psychotic when he wrote the Red Book?

Jung himself asked this question. His answer was no, and most scholars agree. He remained professionally active throughout the period, seeing patients and writing academic papers. The key difference from psychosis is that he retained what he called the "standpoint of consciousness" — he could enter the visions and return from them at will. He was choosing to go in.

How does the Red Book connect to Jung's later theory of individuation?

Almost every major idea Jung published after 1920 — the shadow, the anima, the Self, individuation, active imagination, and the archetype — has its first, raw appearance in the Red Book. He described the book as the prima materia, meaning the raw material, from which his entire published psychology was refined. It was the laboratory, and everything else was the result.
