How to Chant Om: A Simple, Correct Practice

Learning how to chant Om takes about a minute; learning to chant it well is the practice of a lifetime — and, happily, the two are not far apart. Om needs no memorising, no qualification and no equipment. It asks only for a slow breath and a little attention. What follows is everything you need to begin today, and to keep the practice honest as it deepens.

The syllable itself

Om is the praṇava, the primordial sound — in the tradition, the syllable said to contain all sounds and to be the nearest audible name of the whole of reality. Before we take it apart, hear how much weight it carries in the Bhagavad Gītā, where Krishna names it the single imperishable word.

ओमित्येकाक्षरं ब्रह्म व्याहरन्मामनुस्मरन्।
यः प्रयाति त्यजन्देहं स याति परमां गतिम्॥

om ity ekākṣaraṃ brahma vyāharan mām anusmaran · yaḥ prayāti tyajan dehaṃ sa yāti paramāṃ gatim

Uttering the one imperishable syllable Om, which is Brahman, and remembering me — one who so departs the body reaches the supreme goal.

You do not need to hold all of that in mind to chant. But it is worth knowing that when you sound Om you are joining a very old current. For the full account of what the syllable means, see the meaning and significance of Om.

The three mātrās: A-U-M

Om is written as one letter but sounded as three units — mātrās — that flow into one another: A (a), U (u) and M (m), together auṃ. Chanting it is simply moving cleanly through these three.

• A — an open aaa, as in "father," begun deep in the throat and belly with the mouth wide. This is the sound of opening.
• U — the aaa rolls forward into ooo as the lips round and the sound moves into the mouth. Feel it travel outward from the chest to the lips.
• M — the lips close and the sound becomes a humming mmm, resonating in the head and behind the face, then thinning into silence.

The Māṇḍūkya Upaniṣad reads these three as the three states of consciousness — A for waking, U for dreaming, M for deep sleep — and, crucially, the silence after the hum as turīya, the fourth: the still awareness in which all three come and go. So the full chant is not three sounds but four movements, and the last one is quiet.

Posture and setting

Sit upright — on a chair, a cushion, or the floor — so the spine is tall and the breath can move freely; a slumped chest muffles the sound and the mind alike. Let the hands rest easily, shoulders drop, eyes close. You need no special place, only one where you will not be interrupted for a few minutes. Early morning suits it well, when the house and the mind are both still. If sitting itself is new to you, our guide on how to meditate with the Bhagavad Gītā covers posture in more depth.

Breath and the sound

Everything hinges on the breath. Take a slow, easy inhale through the nose, filling the belly and then the chest. Then, on a single long exhale, sound the whole syllable: roughly a third of the breath on aaa, a third on ooo, and a third on the mmm, letting the hum fade as the breath runs out. Keep the pitch low and comfortable — you are not performing, only resonating. Then let the next breath come in naturally before the next Om. Done this way, chanting Om is also a slow-breathing exercise, which is much of why it calms the nervous system so reliably.

Pay particular attention to the humming mmm, which most beginners cut short. Held gently, it sends a low vibration up through the chest, throat and skull that you can actually feel — many people find it settles the mind faster than the vowels do. Let it be the longest part of the sound, thinning slowly rather than stopping abruptly, so that the syllable seems to dissolve into the silence rather than end at it. That seamless fade from sound into quiet is the whole art of chanting Om; get that, and the rest follows.

How many, and counting

Begin with three rounds; grow to nine or eleven as it becomes familiar. The traditional full count is 108, often kept on a mālā of beads so the fingers, not the mind, do the counting. But numbers are only a container. It is far better to chant three Oms slowly, feeling each one, than to hurry through a hundred. Let the count serve the attention, never replace it. If a longer verse appeals once Om feels natural, the Gāyatrī mantra is the classic next step and opens with Om itself.

Common mistakes

A few errors are almost universal at first, and easy to correct:

• Rushing. By far the most common. A clipped, quick "ohm" loses the long resonance that does the work. Let each one take a whole slow breath.
• Skipping the silence. The pause after the hum is not dead time between repetitions; it is the practice — the fourth, turīya. Rest in it.
• Straining. Forcing volume or a low pitch tires the throat and tightens the body. Stay well within an easy range.
• Chasing an experience. Some days feel profound, most feel ordinary. Do not grade the sessions; just keep sounding it. The steadiness is the point, not the fireworks.

A simple daily practice

Here is a complete practice small enough to keep. Once a day, sit upright somewhere quiet. Take three slow breaths to arrive. Then chant Om nine times, each on a long exhale, moving through aaa–ooo–mmm and resting in the silence after each. When the ninth fades, do not rush to stand — sit for thirty seconds in the quiet the chanting leaves behind, and simply notice how you feel. That silence is Om still working. Do this daily rather than occasionally, and within a couple of weeks the sound will begin to come to you unbidden in tense moments — which is exactly when it is most useful.
