Ujjayi & Nadi Shodhana — the first two named breaths in your toolkit
From this lesson on, the breath starts having names. The two that open a teacher's toolkit sit at opposite ends: Ujjayi — the “ocean breath” — is the breath for moving, a sound like surf that holds the rhythm of a whole sequence; while Nadi Shodhana — alternate-nostril breathing — is the breath for stillness, bringing a cluttered head back to balance. With these two in hand you already have one tool to “hold the rhythm” and one to “settle” for any session you teach.
Close the throat slightly and the breath turns into the sound of the sea
Normally the throat is wide open and the air goes in and out silently. In Ujjayi the student closes the throat slightly — leaving a narrow gap — so the air brushes through it and makes a low, even sound, like waves against a shore. Both the in-breath and the out-breath go through the nose, mouth closed, but the sound comes from the throat. The Sanskrit name means “victorious, rising” — it carries the sense of being master of your own breath.
If a student is curious about where the sound comes from, the short answer is: the glottis — the gap between the two vocal folds in the throat, the same place the voice comes from. Ujjayi only narrows that gap a little. No need to go deeper; what matters is the feeling, not the anatomical name.
Fog a mirror, then close the mouth
Step one: have the student open the mouth and breathe one long breath onto the palm as if fogging a mirror — they hear a slightly hoarse “haaa” in the throat. Step two: keep that same gentle narrowing but close the mouth, letting the air out through the nose. The “haaa” now becomes the rushing of surf. For a class that struggles to picture it, “the throat as it is when you whisper very softly” usually lands straight away.
New students often assume the sound has to be loud to be right. Correct that immediately: the Ujjayi sound only needs to be loud enough for the person breathing to hear it, quiet and even. The smoother and lighter the sound, the more comfortable the throat. A loud hiss or a strained rasp is the sign of over-gripping — the throat goes dry and raw, the shoulders hitch up, and the student ends up tense instead of released. If you see shoulders shrugging, a clenched jaw or a reddened, straining face, have them drop back to ordinary breathing for a few rounds and start again more lightly.
The anchor line that holds the rhythm of a vinyasa sequence
Rhythm: the sound becomes a natural metronome — one movement to one breath, in or out. Focus: the surf gives the mind something to hold on to. Warmth: a controlled breath warms the body from the inside. A longer breath: the narrow gap slows the air leaving, so each breath lasts longer and you are less likely to run out partway. Because the out-breath lengthens steadily, students often feel calmer and more comfortable even in the middle of effort — that is a feeling of ease, not a medical effect.
For you, the room's Ujjayi is a gauge of intensity. When the sound starts to rasp, break up or disappear, that is the class telling you it is overloaded and needs to slow down or rest. A class that keeps the sound smooth is a class working inside a safe, comfortable range.
It is not to be held on to at all times. In the deep rest at the end (lying down), let the students drop back to a natural breath. A complete beginner should learn belly breathing solidly first, and only then add Ujjayi. And Ujjayi is at its strongest while the body is moving — for the quiet seated practices such as Nadi Shodhana just below, we breathe gently and normally and do not lay the Ujjayi sound on top. Being able to tell “a breath for moving” from “a breath for stillness” is what lets you design a coherent session.
Close one nostril, breathe through the other — then change sides
Nadi Shodhana (“clearing the channels”) is breathing through alternate nostrils. With the right hand, fold the index and middle fingers lightly into the palm; the thumb rests on the right nostril and the ring finger on the left — pressing only lightly on the soft part to close it, never poking in, never pressing on bone. Keep the shoulders down, lift only the hand and forearm as far as the nose, head straight. If the arm is weak or the shoulder tires, prop the elbow on a knee or change hands.
The order: close the right nostril, breathe all the way out through the left → breathe in through the left → change hands, close the left → breathe out through the right → breathe in through the right → change back. That is one round; starting with an out-breath empties the lungs so the rounds that follow are even and clean. A suggested rhythm for beginners: in on a silent four, out on four or six — a slightly longer out-breath is the more comfortable. Slow, quiet, even, no held breath, no forcing. Three to five minutes is plenty; finish by lowering the hand, breathing naturally, and noticing the difference between before and after.
A doorway that takes a whole room from a noisy rhythm into a quiet one
Because the rhythm is slow and even and the out-breath is drawn out, Nadi Shodhana helps the nervous system shift towards release — it feels comfortable, the mind is less scattered, attention gathers more easily. In other words: it supports balance, settling and focus — it does not cure or treat anything. It sits best right before sitting in meditation, before any quiet sitting, or before bed, as a “doorway” taking a student from the rhythm of the day into the rhythm of stillness. Students can do three to five minutes of it at home before sleep.
If one nostril is blocked by a cold or sinusitis, closing the other one leaves the student unable to breathe and distressed — the technique is simply not suitable then; let them wait until the nose is clear. Anyone with a respiratory condition should ask a doctor first. And as with every breathing practice: at any dizziness, shortness of air or tightness in the chest, stop, lower the hand, breathe normally — the breath should never be pushed to the point of discomfort.
Remind students that the finger pressure is very light — enough to stop the air, not enough to push the nose out of shape or redden the skin. The commonest fault is still breathing too forcefully, or straining to draw the breath out so long that it becomes tense; alternate-nostril breathing is meant to be comfortable, not gripped.
