What Is Om (Pranava)?
Om (ॐ), also called the Pranava, is the most sacred sound in the Hindu tradition - the primordial vibration from which the whole universe is said to have arisen. The Vedas call it the seed of all mantras; nearly every mantra begins with Om.
The Mandukya Upanishad teaches that all that exists - past, present and future - is Om, and even what lies beyond time is Om. It is not merely a sound but a symbol of Brahman, the supreme reality. To chant Om is to attune oneself to the very vibration of existence and to turn the mind toward the divine.
The Three Sounds: A - U - M
Om is made of three sounds - A (अ), U (उ) and M (म्) - which blend into a single, continuous vibration:
- A (अ) arises in the throat, at the very back of the open mouth - the beginning of all sound. It represents creation and the waking world.
- U (उ) rolls forward through the mouth - it represents sustenance and continuity.
- M (म्) closes the lips, the end of sound dissolving into silence - it represents dissolution and return to the source.
Together A-U-M holds the whole cycle of creation, preservation and dissolution - and is linked to Brahma, Vishnu and Shiva. The sound begins, expands and merges back, mirroring the journey of all that exists.
The Three States & the Silence Beyond
The Mandukya Upanishad links the three sounds of Om to the three states of consciousness:
- A = Jagrat (waking) - the world of the senses and the body.
- U = Swapna (dreaming) - the world of the mind and impressions.
- M = Sushupti (deep sleep) - the state of rest where the mind is still.
But Om is more than these three. After the sound fades, there is a fourth - Turiya, the silence beyond A-U-M. This silence is the pure Self, the witness of all three states, untouched and ever-free.
This is why chanting Om and then resting in the silence that follows is a profound meditation: the sound carries us through waking, dream and sleep, and the silence opens onto the stillness of the Self (Atman).
How to Chant Om & Its Benefits
How to chant: 1. Sit comfortably with a straight spine, eyes gently closed, in a quiet place (early morning is ideal). 2. Take a deep breath, and on the out-breath chant A-U-M as one long sound - 'Aaa-Uuu-Mmm' - letting the M hum until the breath ends. 3. Rest in the silence that follows before the next chant. Repeat 7, 11 or 21 times. 4. Feel the vibration in the chest, throat and head.
Benefits (traditional):
- Calms the mind, steadies the breath and lowers restlessness
- Improves focus and prepares the mind for meditation
- Fills the space and the body with sattvic, peaceful vibration
- Turns the attention inward, toward the silent Self
Om can be chanted alone, before any prayer or mantra, or simply as a daily practice to begin and end the day in peace.
Frequently Asked Questions
