Why Silence Is Central in the Mandukya Upanishad

 Twelve verses. One sound. One silence. The whole of Vedanta

Abstract: The Mandukya Upanishad is the shortest of all the principal Upanishads. It contains just twelve verses. In the world of ancient Indian philosophical texts, where some Upanishads run to hundreds of pages and the great epics fill entire libraries, twelve verses is almost nothing. And yet the tradition has consistently held that the Mandukya alone is sufficient for liberation. Shankaracharya called it the most important of all the Upanishads. Gaudapada, whose commentary on the Mandukya is the foundational text of Advaita Vedanta, built an entire philosophical system out of its twelve sentences. The question worth asking is simple: how can something so short contain so much?

The answer lies in what the Mandukya Upanishad is actually doing. It is not making arguments to be followed step by step. It is not providing information to be memorised and recited. It is leading the reader, through a precise and careful movement of attention, to the edge of all possible description and then pointing, with its final verses, into a silence that is not the absence of meaning but the fullness of it. Silence, in the Mandukya Upanishad, is not where the teaching ends. It is where the teaching arrives. This article traces that journey from the first word of the text to the silence that its final verses open into, and explains why that silence is the most important thing the Mandukya has to say.

Introduction: The Upanishad That Ends Where Words Cannot Go

Most sacred texts are long. The Bible, the Quran, the Mahabharata, the Pali Canon of Buddhist scripture, all of them fill volumes. Length, in religious literature, is often a sign of comprehensiveness, of the desire to say everything that can be said about the truth so that no one is left without guidance. The Mandukya Upanishad takes exactly the opposite approach. It is as if its authors recognised that the truth they were pointing toward could not be reached by accumulating more and more words, and that at some point the most honest and the most useful thing a text could do was to lead the reader, as efficiently as possible, to the place where words stop working and something else takes over.

That place is what the Mandukya calls Turiya, the fourth. Not the fourth state of consciousness, exactly, though it is sometimes described that way. More precisely, Turiya is the ground in which all three ordinary states of consciousness, waking, dreaming, and deep sleep, arise and dissolve. It is the awareness that is present through all three states without being limited to or defined by any of them. And it is, the Mandukya insists, what you are at the most fundamental level of your existence. The journey to Turiya is the journey to silence, because Turiya, by its very nature, cannot be described in words. It can only be recognised in the stillness that opens when all description has been exhausted.

This article follows the Mandukya Upanishad through its twelve verses, explaining each movement of the text in plain language, and showing how every step of the argument is also a step toward the silence that the text considers the deepest possible truth about the nature of the self and of reality.

Part One: Om Is All This

The First Verse and the Claim That Contains Everything

The Mandukya Upanishad opens with a declaration so enormous that it is easy to read past it without fully registering what is being said. The first verse says simply: Om. This syllable is all this. All that was, all that is, all that will be, all of this is indeed Om. And even what transcends the three divisions of time, that too is only Om.

Every word of this opening matters. Om is not being introduced as a useful symbol, a traditional invocation, or a culturally significant sound. It is being identified with all of reality. Not compared to all of reality, not described as a representation of all of reality, but equated with it. The syllable Om and the totality of existence are, the Mandukya says, one and the same thing. This is the most radical possible starting point for a philosophical text, and the Mandukya does not apologise for it or soften it. It simply states it, and then spends the next eleven verses explaining what it means.

Why does the text begin with Om rather than with a description of Brahman or the Atman? Because Om is a sound that has a unique property among all possible sounds: it contains, within its three constituent elements and its concluding silence, a complete map of consciousness. The tradition identifies the sound Om as being made up of three letters in Sanskrit: A, U, and M. These three letters correspond to the three ordinary states of human consciousness. And the silence that follows the sound of M, the silence into which the resonance of Om dissolves, corresponds to the fourth, Turiya. The Mandukya is telling you, in its very first verse, that the whole of what it is about to teach is already contained in the single syllable that every Vedic recitation begins with. If you can truly hear Om, you have already heard everything.

The Three Letters and the Three States

The second verse of the Mandukya introduces the concept of the four quarters of consciousness, the four Padas, which will be the main subject of everything that follows. The text says that the Atman is fourfold, that it has four aspects or quarters, each corresponding to a different dimension of conscious experience. Three of these four dimensions are the states of consciousness that every human being moves through every single day of their life. The fourth is the ground of all three.

The first state is Vaishvanara, the waking state. When you are reading these words, you are in the waking state. Your senses are open and engaged with the physical world. You are aware of the room around you, the weight of the book or device in your hands, the sounds of the environment. The waking state is the state of outward-turned consciousness, consciousness oriented toward the external world of objects and experiences. In the Mandukya's framework, this state corresponds to the letter A in Om, the first letter, the most open sound in the human voice, the sound produced with the mouth wide open and the breath flowing freely outward.

The second state is Taijasa, the dreaming state. Every night, when your body rests and your senses withdraw from the outer world, another world appears: the dream world. In that world you see, hear, feel, and experience things with complete vividness, and while the dream is happening it is entirely convincing. You experience genuine emotion in dreams. You make decisions, feel fear, feel joy. The dreaming state is the state of inward-turned consciousness, consciousness creating its own world from the materials stored in memory and imagination. It corresponds to the letter U in Om, the middle sound, produced with the lips beginning to close and the sound turning inward from its most open position.

The third state is Prajna, the state of deep dreamless sleep. This is the state you enter every night after dreaming has ceased and before waking begins. In deep sleep there is no experience of a world, inner or outer. There is no specific thought, no emotion, no narrative. And yet it is not nothing: people emerge from deep sleep feeling rested, refreshed, having received something, even though they cannot say what they experienced. The Mandukya describes this state as a mass of pure awareness with bliss as its face, the closest that ordinary consciousness comes to its own deepest nature without quite recognising itself. It corresponds to the letter M in Om, the sound produced with the lips completely closed, the most inward and the most unified of the three sounds, just before the sound ends.

Part Two: The Sound Ends and the Fourth Begins

Turiya: Not a State but the Ground of All States

And then the sound of Om ends. The M closes into silence. And it is in that silence, the Mandukya says, that the fourth, Turiya, is to be found. But found is perhaps the wrong word, because Turiya is not something hidden that you discover after looking for a while. It is something always already present that you simply have not noticed, because all your attention has been directed toward the three states that arise within it.

The Mandukya's seventh verse, which introduces Turiya, is one of the most carefully worded passages in the entire Upanishadic literature, and it is worth sitting with every phrase. The text says that the fourth is not that which is conscious of the inner world, and not that which is conscious of the outer world, and not that which is conscious of both worlds, and not a mass of consciousness, and not conscious, and not unconscious. It is unseen. It cannot be grasped. It has no distinguishing features. It cannot be thought about. It cannot be pointed to. It is the essence of the certainty of the self. It is the cessation of all phenomena. It is peace. It is bliss. It is non-dual. This is the Atman. This is what must be known.

Read that passage slowly and you will notice something remarkable happening. The Mandukya begins by saying what Turiya is not. It is not conscious of the inner world, meaning it is not the dreaming state. It is not conscious of the outer world, meaning it is not the waking state. It is not conscious of both worlds simultaneously. It is not a mass of consciousness, meaning it is not the deep sleep state. It is not conscious in the ordinary sense, meaning it is not any identifiable experience. And it is not unconscious, meaning it is not simply the absence of awareness. Every possible description has been excluded.

What remains after all those exclusions? The text gives the answer in a series of the most economical and the most beautiful phrases in Sanskrit philosophy. Peace. Bliss. Non-dual. The Atman. What remains after every possible description has been removed is not nothing. It is the awareness itself, which was never any particular state and never any particular experience, but which was the silent, steady, utterly present ground within which all states and all experiences arose. Turiya is not a fourth thing added to the other three. It is what all three arise in. It is the silence that was always already present underneath the sound of all three.

Why Silence Cannot Be Described and Must Be Experienced

Here is the central challenge that the Mandukya Upanishad honestly acknowledges: you cannot describe silence with words. The moment you say something about it, you have broken it. The moment you point to it, it has already become an object of attention, and an object of attention is not the awareness that is doing the attending. Every attempt to capture Turiya in a concept produces a concept, which is precisely not Turiya. Turiya is what is aware of concepts, not another concept to be aware of.

This is not a failure of the Mandukya. It is the most honest philosophical observation possible. And it is the reason why the Mandukya is structured the way it is: twelve verses that systematically eliminate every possible description, not to leave you with nothing but to leave you with the one thing that is left when everything describable has been eliminated. You cannot think your way to Turiya. You can only stop thinking enough to notice that something has been present through all the thinking, something that was not produced by the thinking and is not disturbed when the thinking stops.

The Chandogya Upanishad, in a different context, makes a similar point when it says that Brahman is where the mind goes and does not return, having no words. The Brihadaranyaka says Neti, neti, not this, not this, until the negation itself reveals what cannot be negated. The Mandukya does the same thing through the structure of Om: three sounds that are knowable, describable, experienced, followed by a silence that is none of those things. The three sounds prepare you for the silence. The silence is the point.

Part Three: Gaudapada and the Deeper Silence

The Karikas: When Philosophy Points Beyond Itself

The Mandukya Upanishad does not stand alone in the tradition. It is accompanied by the Mandukya Karikas of Gaudapada, the teacher who was Shankaracharya's teacher's teacher, the founder of the Advaita Vedanta lineage as a formal philosophical school. Gaudapada's Karikas are a commentary on the Mandukya that expand its twelve verses into several hundred, developing the philosophical implications of the Upanishad's teaching on the four states and the nature of Turiya into one of the most rigorous and complete systems of non-dual philosophy ever constructed.

Gaudapada's central contribution is the doctrine of Ajativada, which means the doctrine of non-origination. He argues, building directly on the Mandukya's teaching about Turiya, that nothing has ever actually been created. The entire apparent world of multiplicity and change, of birth and death, of one thing becoming another, is, from the perspective of Turiya, an appearance within the one, unchanging, non-dual awareness. Nothing comes into being. Nothing ceases to be. There is only the one awareness, appearing to itself as a world of many things through the mysterious power of its own creative capacity.

This teaching sounds extreme. But Gaudapada's argument for it is philosophically precise and practically important for understanding why silence is central to the Mandukya. He asks: what is the waking world like? It appears real, solid, external, permanent while you are in it. Now consider the dream world. It also appears real, solid, external, permanent while you are in it. But the moment you wake up, you recognise instantly that the dream world was not external, not independent, not truly other than the mind that was dreaming it. The whole vivid world of the dream, with its people and its places and its dramas and its dangers, was produced by and within your own awareness.

Gaudapada asks: what makes you confident that the waking world is different in its fundamental nature? From within the waking state, of course, it seems entirely different. It seems solid and real and independent in a way the dream world was not. But that is exactly what the dream also seemed like from within it. The waking state has no independent criterion by which to judge itself superior in reality to the dream, because the very instrument of judgment, the waking mind, is itself part of what is being judged. The only truly independent vantage point is Turiya, the awareness that is equally present in and through waking, dreaming, and deep sleep, and which is not produced by any of the three.

From Turiya's vantage point, both the waking world and the dream world arise in the same way: within awareness, from awareness, as appearances of awareness. Neither is more ultimately real than the other. Both are modifications of the one non-dual consciousness. And the recognition of this is not a depressing discovery. It is, the Mandukya and Gaudapada together insist, the most liberating recognition possible, because it means that the small, frightened, separated self that seems to be trapped in a solid and threatening world is itself only an appearance within the one awareness, and that the one awareness, which is what you truly are, is never trapped, never threatened, never limited by any of the forms it appears as. It is always free. Always full. Always silent in the deepest sense, because it is never disturbed by any of the noise that arises within it.

The Silence Between Thoughts Is the Same Silence as Turiya

Here is the most practically useful implication of the Mandukya's teaching on silence, and the one most directly accessible to an ordinary person who is not a professional philosopher: the silence that the Mandukya is pointing to is not somewhere else. It is not a special state that requires years of practice to enter. It is present right now, in this very moment, as the background of your experience.

You are reading these words. Between each word, there is a tiny gap. Between each sentence, a slightly longer one. Between each thought that arises in your mind as you read, there is a moment of silence, a brief interval in which the previous thought has dissolved and the next has not yet arisen. In that interval, what is there? Not nothing. There is awareness. There is presence. There is the quiet sense of being here, being conscious, being alive to this moment. That quiet presence in the gap between thoughts is the same silence that the Mandukya calls Turiya. It is not a special experience reserved for advanced meditators. It is the ordinary background of every moment of conscious experience, usually overlooked because the attention is so fully absorbed in the foreground of thoughts and sensations and stories.

The practice that the Mandukya Upanishad implicitly recommends, the practice that the tradition of Advaita Vedanta has developed in many forms from Gaudapada through Shankaracharya through Ramana Maharshi to teachers of the present day, is precisely the practice of noticing this background. Not manufacturing it, not achieving it through effort, not working yourself into a special state. Simply noticing what is already here. Turning the attention from the foreground of experience to the background within which the foreground arises. Letting the sound of the Om in your mind dissolve into the silence that follows. And recognising, in that silence, something that has always been present, something that the tradition dares to say is what you most fundamentally are.

Conclusion: The Upanishad That Teaches by Stopping

There is a paradox at the heart of the Mandukya Upanishad that every reader eventually has to sit with: it is a text whose entire purpose is to lead you beyond texts. It is a teaching whose conclusion is that the teaching cannot take you all the way. Words can describe the three states of waking, dreaming, and deep sleep, because those states are objects of description, experiences that can be talked about. But Turiya, the ground of all three, the silence that underlies all sound including the sound of Om, cannot be described. It can only be recognised directly, in the stillness of attention turned back on itself.

This is why the Mandukya is so short. A longer text would simply be more words, and the problem that the Mandukya is addressing is not a shortage of words. It is a surplus of attention directed outward. Twelve verses are enough to map the territory, to show you the three states and point to the fourth, to give the mind enough of a framework that it can, at least for a moment, stop its habitual outward movement and rest in the silence that was there all along. That is what the twelve verses are for. They are a hand pointing at the moon. The moon itself is the silence.

The Mandukya Upanishad begins with Om. Om is all this. All that was, all that is, all that will be is Om. And even what transcends the three divisions of time is only Om. If you chant Om slowly, you can hear it: the A rising from the belly, the U moving forward through the chest, the M closing at the lips, and then the sound ends. And what is left? Silence. The same silence that was there before you began. The silence that the sound arose from and returns to. The silence that was never not there. The Mandukya Upanishad calls that silence the Atman. It calls it Brahman. It calls it the fourth. It says it is what you are. And then, having said that much, it says no more. Because saying more would only take you further from the silence it is trying to introduce you to. The loudest teaching is a silence. And the silence is enough.

Om ity etad aksharam idam sarvam

Tasyopavyakhyanam

Bhutam bhavad bhavisyad iti sarvam omkaara eva

Yac canyat trikalaatitam tad apy omkaara eva

Om. This syllable is all this.

All that was, all that is, all that will be is indeed Om.

And what transcends the three divisions of time, that too is Om.

(Mandukya Upanishad 1.1)
