Listening to the Unstruck Sound

A sound nobody makes

Every sound you have ever heard was made by two things touching. A hand on a drum, air across a reed, a voice against the throat, rain on a roof. The yogis spoke of another kind of sound, one that is not made by anything striking anything. They called it anāhata nāda, the unstruck sound. It is the same word that names the heart lotus, Anāhata, and that is no accident.

At the end of the Haṭha Yoga Pradīpikā, after all the postures, the breath work, the locks and the seals, Svātmārāma does something that surprises many first-time readers. He sets almost all of that machinery to one side and turns to listening. Of all the ways the mind can be dissolved, he says, attending to the inner sound is the chief one. And he offers it explicitly to people who cannot follow the subtler paths of knowledge.

We find that deeply moving. The most refined practice in the book is also the one most freely given.

In this piece we walk through what the text actually says (roughly verses 4.65 to 4.102, though the numbering shifts by one between editions), look at the four stages it describes, and then set out a simple, careful way to begin.

Where the teaching comes from

Svātmārāma introduces the practice as the method of Gorakṣanātha, the great Nāth teacher. He then tells us that Ādinātha, Śiva himself as the first teacher, gave a crore and a quarter ways of laya, of absorption or dissolving. A crore is ten million, so this is a deliberately enormous number: the tradition is saying that there are countless doors. Among them all, the Pradīpikā ranks attention to nāda as the foremost.

The instructions are brief. Sit in a steady posture, rest in the inward gaze called śāmbhavī mudrā, and listen with a one-pointed mind to the sound heard within, on the right side. Then the text describes closing the ears, eyes, nose and mouth, so that a clear sound becomes audible in the purified central channel, the suṣumnā. Later yoga manuals call this closure of the senses with the fingers ṣaṇmukhī mudrā, the seal that closes the gates of the senses.

Notice what is happening here. The Pradīpikā does not ask you to imagine a sound, chant one or produce one. It asks you to turn around and notice what is already sounding.

The idea is older than this one book, and it is not confined to haṭha. The Vijñāna Bhairava Tantra of Kashmir gives several practices of sound: resting in the unstruck sound that flows without a break like a swift river; listening to the long notes of a stringed instrument until they die away into space; chanting Oṃ and resting in the emptiness at the end of its long fading. The Dhyānabindu Upaniṣad speaks of a nāda above the seed-syllable, and of a state beyond nāda when even that sound ceases.

The four stages

The Pradīpikā says that every kind of yoga passes through four states, and it uses the inner sound to describe them. This map is one of the most precise in haṭha literature, so it is worth reading slowly. Each stage pairs a knot (granthi) with a place in the body, a quality of inner space and a kind of sound.

Ārambha, the beginning. Through breath practice the knot of Brahmā in the heart is pierced. A bliss arises in the void of the heart, and sounds like the tinkling of ornaments are heard within the body. The text adds that the body becomes radiant, fragrant and free of disease.

Ghaṭa, the jar. The breath unites and enters the central channel. The posture becomes firm and the practitioner grows wise. Now the knot of Viṣṇu in the throat is pierced, and in that greater void a sound like a kettledrum is heard.

Paricaya, familiarity. A sound like a mardala, a deep double-headed drum, arises in the space between the eyebrows. The breath reaches what the text calls the great void, the home of all attainments. A natural, unforced bliss arises, beyond pain, ageing and hunger.

Niṣpatti, completion. The knot of Rudra is pierced and the breath reaches the seat of the Lord. The sound now is like a flute or a vīṇā. Mind and sound become one, and the text calls this rāja yoga.

A few honest points about this map. First, it is a description written from the far end of the path, not a checklist for a beginner. Second, the knots and their placement are given differently in other texts. The Pradīpikā places Brahmā’s knot in the heart; many later and modern teachers place it lower, near the root lotus where Kuṇḍalinī lies coiled around the Svayambhū-liṅga, covering the door of the central channel. Neither placement is wrong in its own system. We simply note that the traditions do not speak with one voice.

And third, the stages are not achieved by listening harder. In the Pradīpikā they follow from the whole of the practice, breath, locks and devotion together. Sound is how the progress announces itself.

What you may hear

The text then lists the sounds in three broad phases. At first they are loud and many: like the surging ocean, thunderclouds, a kettledrum, the jingling of a jharjhara. In the middle they become like a conch, a mardala drum, bells and a horn. At the end they are fine and high: little tinkling bells, a flute, a vīṇā, the humming of bees.

The bee keeps appearing in this literature. The Ṣaṭ-cakra-nirūpaṇa, describing Kuṇḍalinī herself as she lies coiled in the root lotus, compares her murmur to the sound of swarms of bees maddened with love. The breath practice called bhrāmarī, the bee breath, is built around that same sound.

Other texts give other lists. The Haṃsa Upaniṣad names ten sounds, in this order: a faint sound like the syllable ciṇī, then ciṇī-ciṇī, then a bell, a conch, a stringed instrument, cymbals, a flute, a drum, a double drum and finally thunder. It teaches that the first nine are to be passed through and the tenth sought. Notice that its order runs almost opposite to the Pradīpikā’s, from fine to loud. Again, the maps differ. What they share is the movement of attention inward.

In practice, most people who sit quietly for a while will notice some inner sound. A high ringing, a soft hiss, something like wind in wires, a hum like distant traffic, a faint pulse. It does not have to match any list. Please do not judge your practice by whether you hear a flute.

Even while loud sounds are heard, keep attending to the subtle ones.After Haṭha Yoga Pradīpikā 4.88

How to begin, step by step

You need nothing special. A quiet room helps, and so does the evening, when the house has settled and the road outside has gone still. Allow about twenty minutes.

Settle the body. Sit on a cushion or a chair with your back upright but not stiff. Let the shoulders drop. If sitting is painful, lie down, though you may find yourself drifting into sleep.

Calm the breath. For a minute or two, breathe in through the nose comfortably and breathe out slowly, a little longer than the in-breath. If you like a count, try in for 4 and out for 7 or 8. Then let the count go and let the breath find its own rhythm.

Close the outer world gently. The classical seal places the thumbs on the ears, the index fingers on the closed eyes, the middle fingers beside the nostrils and the remaining fingers around the lips. That is beautiful but tiring for the arms. A simpler start is to press the small flaps in front of the ear canals lightly with the thumbs, elbows resting on a cushion or the knees, or simply to use soft earplugs. Close the eyes.

Listen for whatever is there. Do not hunt for a particular sound. Find the loudest inner sound you can and rest your attention on it, the way you might listen to a stream from the bank. The Pradīpikā mentions the right ear; if the sound seems clearer on that side, favour it, but do not strain.

Move towards the subtler. After a while you may notice a finer sound underneath or beside the first. Let attention drift towards it, without abandoning the first by force. This is the heart of the method: always leaning a little towards the more subtle sound.

Let the hands rest. After five or ten minutes, lower the hands. Many people find the sound continues without the ears being closed. Keep listening.

When the sound fades, stay. Do not chase it. The Pradīpikā says that while sound is heard there is still the sense of space, and when it disappears, that is the supreme. The Vijñāna Bhairava says something similar of a fading note: rest in the openness it dissolves into. That silence is not an absence. It is what the sound was resting in all along.

Close with the body. Before you get up, feel your weight on the seat and your feet on the floor. Open the eyes slowly. Drink some water.

Why sound works on the mind

The Pradīpikā is wonderfully vivid here, and its images explain the method better than any theory. The mind absorbed in nāda, it says, is like a bee drinking nectar, which no longer cares for the scent of the flower. It is like a wild elephant brought under control by the goad of the inner sound. It is like a bird with clipped wings that stops flitting about. It is like a snake that forgets its restlessness on hearing the sound. And it is like fire that goes out together with the wood it was burning: the mind, working with nāda, becomes still along with it.

That last image is the key. Most concentration practices give the mind something to hold. Nāda gives it something that slowly disappears. As the attention follows the sound into finer and finer layers, the one who is listening grows quieter too.

The text adds one more line we love. Whatever is heard as sound, it says, is śakti. The formless one beyond all the principles is the Lord. In our language: the sound is her, the Goddess as vibration, and the silence she leads into is Śiva. Listening is a way of following her home.

Practising with care

Some people find inner ringing uncomfortable, or it reminds them of tinnitus. If that is you, there is no need to force this practice. Listening to the fading tone of a bell or a singing bowl, and then to the silence after it, trains the same attention in a gentler way.

A practical word on health. If you notice a new ringing that is constant, or that is in one ear only, or that comes with hearing loss, dizziness or pain, please see a doctor before treating it as a spiritual sound. Most inner sounds are harmless, but these signs deserve a proper check, and getting one costs you nothing on the path.

Others find that nāda opens quickly and strongly once the energy is moving. If the sounds become loud, constant or frightening, if they disturb your sleep, or if you begin to hear voices or anything that feels like it is speaking to you, slow down. Spend more time with grounding: walking, warm food, sleep, simple work with the hands. Talk to an experienced teacher, and if you feel confused about what is real, to a mental-health professional as well. Sound is one of the ways she announces herself. It is never something to push.

And if you hear nothing at all for weeks, that is completely normal. The Pradīpikā itself treats nāda as the fruit of long practice. Keep sitting. The listening itself is the practice, and a quieter mind is already the first stage of the sound.

Begin with ten minutes, three or four evenings a week. Note what you hear, if anything, in a simple log. Over a season, you may be surprised by how much was sounding all along.
