You know what you mean before you know how to say it.
Everyone has stood in that gap. The thought is complete โ you can feel its shape, its weight, whether it is an objection or an agreement โ and yet no words have arrived. Then they arrive, and they are not quite it. Something was lost between having the thought and saying it.
Indian philosophy took that gap seriously and asked an obvious question: if the meaning existed before the words, what was it made of?
The answer became one of the most precise maps in the entire yogic tradition โ four levels of sound, descending from the undifferentiated to the audible. Para, Pashyanti, Madhyama, Vaikhari.
This is not a mystical curiosity. It is the structural backbone of Nada Yoga, and it explains why sound practice is organised the way it is: why chanting moves from loud to whispered to silent, why the tradition treats listening as a discipline rather than a preparation, and why a mantra is not considered finished when you stop saying it.
What "Four Stages of Sound" Actually Means
The four are levels of vak (เคตเคพเคเฅ) โ speech, voice, utterance. Not four different sounds, and not four techniques. Four grades of the same thing, from most subtle to most gross.
An analogy that holds reasonably well: ice, water, vapour, and the atmospheric conditions that produce all three. Different states, one substance. Moving between them is a change of density, not a change of identity.
The critical point, and the one most often missed: these levels exist simultaneously. Vaikhari is not something that happens after Para finishes. When you speak a word, all four are present โ three of them simply escape notice.
That is the practical claim. Not that subtler sound exists somewhere far away, but that it is operating in you right now, beneath the threshold of attention.
The Vedic Seed
The framework has a specific origin. In a much-discussed verse of the Rig Veda, speech is said to be measured in four quarters: the wise know all four, three lie hidden and do not stir, and human beings speak only the fourth.
Three concealed. One audible.
That single verse is the germ of everything that follows. It establishes, thousands of years before the system was formalised, that what we call speech is a fraction of speech โ and that the remainder is not missing but motionless.
An Honest Note on the Sources
Most articles on this subject present the four levels as a single ancient teaching. The actual history is more interesting, and knowing it makes the map easier to read.
Bhartrhari, the fifth-century grammarian-philosopher, describes three levels in his Vakyapadiya: Pashyanti, Madhyama, and Vaikhari. In his system Pashyanti is the highest โ identified with Shabda Brahman itself, and with pratibha, the flash of intuitive understanding that precedes articulation. He does not name a fourth above it.
Abhinavagupta and the Kashmir Shaiva tradition give four, adding Para vak โ supreme speech โ above Pashyanti, identified with the undifferentiated consciousness of Shiva and with Shakti as its self-awareness. In this framework Para is the source, and the other three are what she becomes when differentiation begins.
Different schools โ grammarians, Mimamsakas, tantrics, Vedantins, the Upanishadic tradition โ each work with these terms slightly differently, and their bodily correspondences vary too.
So when a teacher presents the four levels as one seamless doctrine, they are smoothing over a real philosophical conversation. The four-level version used in Nada Yoga is essentially the tantric one, and it is worth knowing that the fourth level was a considered addition rather than an original given.
The Four Levels
The tradition describes these descending โ Para becoming Vaikhari โ because that is the order of manifestation. But a practitioner meets them in the opposite order, so that is how they are set out here.
Vaikhari โ Articulated Sound
Vaikhari is speech you can hear. Sound that has fully emerged: divided into syllables, sequenced in time, produced by breath moving through the vocal apparatus, and audible to someone else.
The name is traditionally connected to vikhara, the gross body โ vaikhari is sound that has taken bodily form.
Its defining features are division and sequence. A spoken sentence arrives one piece at a time. You cannot hear the end of it while hearing the beginning. Meaning must be assembled.
It is usually located at the throat and mouth.
This is where all sound practice begins, and there is nothing lesser about it. Chanting aloud, kirtan, mantra spoken clearly โ this is the level at which the tradition insists on precision, because vaikhari is the only level you can correct. Pronunciation is a vaikhari discipline.
Madhyama โ Intermediate Sound
Madhyama means "middle" โ sound that exists in the mind but not in the air.
This is the inner voice. Silent recitation. The sentence you rehearse before saying it. Reading these words without moving your lips is madhyama in operation right now.
Bhartrhari associates it with buddhi, the discriminating intellect. It still has words, still has sequence, still has grammar. Its whole structure is the structure of articulated speech โ minus the air.
It is generally located at the heart region, though sources differ.
Crucially, madhyama is fully accessible. Every practitioner can move between vaikhari and madhyama deliberately, and this transition is the first real step in mantra practice: chanting aloud, then whispering, then repeating mentally with the same clarity you had out loud.
Most people discover something uncomfortable here โ mental repetition is harder to hold steady than spoken repetition, because there is no air, no muscle, and no sound to catch you when attention slips. That difficulty is the practice working.
Pashyanti โ Seeing Sound
Pashyanti means "the seeing one," from โpaล, to see. Sound apprehended as vision rather than as sequence.
This is the level the opening of this article was pointing at. The thought you have before the words: complete, undivided, present all at once.
Its defining feature is the absence of sequence. Where madhyama unfolds in time like a sentence, pashyanti is whole. There is no beginning and end because there is no order. And at this level word and meaning are not yet two things โ the split between the sign and what it signifies has not occurred.
Bhartrhari identifies it with pratibha: the sudden flash in which you grasp an entire idea before any of it is verbal.
It is usually located at the navel region.
A necessary caution here. The ordinary experience of "knowing what you mean before you say it" is a useful pointer toward pashyanti, but the tradition would not call it pashyanti. Ordinary pre-verbal knowing is still shot through with mental structure โ still madhyama, just not yet linguistically resolved. Pashyanti proper is a meditative attainment, not an everyday cognitive event.
The pointer is genuinely useful. It is just not the destination.
Para โ Supreme Sound
Para means beyond, supreme, transcendent. In Kashmir Shaivism, Para vak is speech in its undifferentiated state โ described by Abhinavagupta as the luminous vibration of pure consciousness before any division at all.
At this level there is no distinction between sound and silence, between word and meaning, between the one who knows and what is known. Not because these have been merged, but because they have not yet separated.
It is sometimes located at the base of the spine, and sometimes given no location, on the reasonable grounds that location is itself a form of differentiation.
Para cannot be described accurately, and any description makes it into something it is not โ the moment you say what it is, you have used vaikhari to point at what precedes even pashyanti. The texts acknowledge this openly rather than pretending otherwise.
What can be said is what it does. Para is the source. The other three are what it looks like from progressively further away.
Two Directions
The map runs both ways, and this is the part that makes it useful rather than ornamental.
Descent โ how sound manifests. Para condenses into Pashyanti, which divides into Madhyama, which emerges as Vaikhari. Undifferentiated to differentiated, whole to sequential, silent to audible. This is the cosmological direction, and it mirrors the manifestation of the world itself in the doctrine of Shabda Brahman.
Ascent โ how practice works. Vaikhari refines into Madhyama, which subtilises toward Pashyanti, which resolves into Para. Audible to inaudible, sequential to whole, gross to subtle.
The two directions are the same road.
This is why the tradition is confident that sound practice leads somewhere. You are not inventing a route inward. You are walking back up one that was already travelled in the other direction โ which is also why the practice feels less like construction and more like recognition when it goes well.
The Correspondence With Waking, Dreaming, and Sleep
A traditional mapping worth knowing, because it appears constantly in teaching and clarifies the whole scheme:
Vaikhari corresponds to jagrat, the waking state โ outward, differentiated, engaged with objects.
Madhyama corresponds to svapna, the dream state โ inward, still full of forms and sequence, but not externally manifest.
Pashyanti corresponds to sushupti, deep sleep โ undifferentiated, without objects, yet not unconscious.
Para corresponds to turiya, the fourth โ the ground of all three.
This is the same fourfold structure the Mandukya Upanishad uses to analyse AUM: A for waking, U for dreaming, M for deep sleep, and the silence that follows for turiya.
Which means chanting Om attentively is not merely similar to this map. It is a rehearsal of it. Every complete Om walks the ladder from Vaikhari to the edge of Para and back.
Working the Ladder in Practice
The classical progression uses three modes of repetition, and it maps directly onto the first two levels.
Vachika japa โ spoken aloud. Clear, audible, correctly pronounced. Vaikhari.
Upamshu japa โ whispered. Barely audible, lips moving, breath still involved. The hinge between levels.
Manasika japa โ mental. No sound, no movement, the mantra repeated internally with full clarity. Madhyama.
A practical session:
Begin with five minutes of vachika japa. Chant your mantra aloud with attention to pronunciation. Let the body feel the vibration.
Move to upamshu for two or three minutes. Reduce the volume until the sound is nearly gone but the articulation remains exact.
Move to manasika and stay there. Repeat the mantra mentally with the same precision you used aloud. Do not let it become vague or fast โ vagueness is not subtlety.
Then, after some minutes, stop deliberately generating the mantra and see whether anything continues on its own.
That last instruction is the one that matters. The tradition's term for a mantra that continues without being produced is ajapa japa โ unrepeated repetition. Whether or not it arrives, the act of stopping and listening is the doorway the whole four-level map exists to describe.
Fifteen to thirty minutes is enough. The progression should be unhurried; rushing to the mental stage before the spoken stage has settled produces a wandering mind, not a subtle one.
Being Honest About What Is Accessible
This is worth stating plainly, because vagueness here does students no favours.
Vaikhari and Madhyama are directly available to anyone. You can move between them at will, today, without preparation. Most of what is actually taught as Nada Yoga practice operates in this range, and there is a great deal of depth in it.
Pashyanti is glimpsed rather than occupied. Practitioners describe moments where the mantra stops being a sequence and becomes a single presence. These tend to be brief and are not producible on demand.
Para is not an experience. It cannot be, since experience requires a subject and an object. Whatever the texts mean by it, it is not something that happens to you while you remain you.
A teacher who claims routine access to the upper levels should be treated with the same scepticism you would apply to any other large claim. The map is valuable as orientation. It is not a set of stages to tick off, and treating it as a ladder to climb competitively is a reliable way to stay at the bottom of it.
Three Things This Is Often Confused With
Not the four avasthas. The Hatha Yoga Pradipika describes four stages of progress in nada practice โ arambha (beginning), ghata (vessel), parichaya (increase), nishpatti (consummation). Those describe the practitioner's development. The four levels of vak describe grades of sound itself. Two different maps, frequently merged in online summaries.
Not the chakras. The bodily locations associated with each level loosely echo chakra positions, but the systems are not equivalent, the correspondences vary between sources, and the four levels are a theory of language rather than a model of subtle anatomy.
Not stages of a technique. You do not "do" pashyanti. These are levels at which sound exists, not exercises to perform.
Common Misunderstandings
1. "You progress through them one at a time and leave the earlier ones behind." All four are present in every act of speech. Practice does not abandon vaikhari โ accurate chanting remains important at every stage of the path.
2. "Pashyanti is just having a thought before you speak it." Ordinary pre-verbal knowing is a helpful pointer but still belongs to the mental level. Pashyanti is defined by the absence of sequence and the absence of any split between word and meaning, which ordinary cognition does not satisfy.
3. "Silent mantra is more advanced, so skip the chanting." Mental repetition is subtler, not better. Attempting it before spoken practice has developed steadiness usually produces a distracted mind congratulating itself on being subtle. The tradition's order is deliberate.
4. "This is one unified ancient teaching." It is a genuine tradition with a real internal history โ three levels in Bhartrhari, four in Kashmir Shaivism, with variation across schools in both terminology and bodily correspondence. The four-level model is well-founded, but it is a particular position rather than a universal given.
Conclusion
You know what you mean before you know how to say it.
The tradition's response to that ordinary experience was not to shrug at it but to follow it โ inward, past the words, past the mental voice, toward whatever is there before either.
Vaikhari is what you can hear. Madhyama is what you can think. Pashyanti is what you can see without looking. Para is what was there before any of these were separate things.
The map's real value is not that it describes exotic states. It is that it tells you which direction to go, and assures you that the direction continues.
You begin with a syllable spoken out loud. That is enough to start with โ and, according to this map, it was never only a syllable spoken out loud.
Frequently Asked Questions
What are the four stages of sound in Nada Yoga?
They are four levels of vak or speech: Para (supreme, undifferentiated), Pashyanti (non-sequential, seen rather than heard), Madhyama (mental, the inner voice), and Vaikhari (audible, articulated speech). They descend from subtle to gross in manifestation, and practice moves back up in the opposite direction.
What is the difference between Vaikhari and Madhyama?
Vaikhari is sound produced in the air and audible to others. Madhyama is the same structured, sequential speech occurring mentally โ the inner voice โ without breath or vocalisation. Moving deliberately between the two is the first real transition in mantra practice.
What does Pashyanti mean?
Pashyanti means "the seeing one." It refers to sound apprehended whole, without sequence, and before word and meaning have separated. Bhartrhari associates it with pratibha, the flash of intuitive understanding that precedes articulation.
Are the four stages of sound the same as the four stages in the Hatha Yoga Pradipika?
No, and this is a common confusion. The four levels of vak describe grades of sound. The four avasthas in the Hatha Yoga Pradipika โ arambha, ghata, parichaya, nishpatti โ describe stages in a practitioner's progress. They are separate frameworks.
Where do the four stages of sound come from?
The seed is a Rig Vedic verse stating that speech has four quarters, three hidden and one spoken. Bhartrhari's Vakyapadiya formalises three levels, and the Kashmir Shaiva tradition โ particularly Abhinavagupta โ adds Para above them to give the fourfold model used in Nada Yoga.
How do I practise moving between the levels?
The classical method is the japa progression: vachika (spoken aloud), then upamshu (whispered), then manasika (mental repetition), holding the same precision at each stage rather than letting the mantra become vague as it quietens.
