In short
A mantra is a sacred formula in Sanskrit, repeated aloud, in a whisper or silently to steady the mind. The word joins man, to think, and -tra, an instrument. The great mantras come from the Vedas (Gāyatrī, Mahāmṛtyuñjaya), the Upanishads (Om, the peace chants) and later devotional and tantric traditions.

Oṃ, the syllable. The Māṇḍūkya Upaniṣad divides it into three sounds, A, U and M: waking, dream and deep sleep. And a fourth part, the silence that follows.
Sit comfortably. Breathe in through the nose, and chant one long Om on the out-breath. Then rest in the silence for one breath. Three times, at your own pace.
Breathe in.
Om. [you chant]
Rest in the silence.
Breathe in.
Om. [you chant]
Rest in the silence.
Breathe in.
Om. [you chant]
Rest in the silence.
The Gāyatrī. A verse of the Ṛgveda, three, sixty-two, ten, attributed to the seer Viśvāmitra and addressed to Savitṛ, the sun as the divine power that sets all in motion. Listen once.
ॐ, भूर् भुवः स्वः। तत् सवितुर् वरेण्यं। भर्गो देवस्य धीमहि। धियो यो नः प्रचोदयात्॥ (oṃ bhūr bhuvaḥ svaḥ / tat savitur vareṇyaṃ / bhargo devasya dhīmahi / dhiyo yo naḥ pracodayāt)
Now line by line. Repeat each line after me, slowly.
ॐ भूर्भुवः स्वः। (oṃ bhūr bhuvaḥ svaḥ)
तत्सवितुर्वरेण्यं। (tat savitur vareṇyaṃ)
भर्गो देवस्य धीमहि। (bhargo devasya dhīmahi)
धियो यो नः प्रचोदयात्॥ (dhiyo yo naḥ pracodayāt)
Our translation: Om. Earth, atmosphere, sky. May we receive that excellent radiance of the god Savitṛ, who shall inspire our thoughts.
Some traditional families prefer that the Gāyatrī be received from a teacher; others open it to all. Whichever you follow, chant it seated, attentive, without haste. This was an extract from Sacred Mantras, on yogide.com.
A mantra (मन्त्र) is a formula of sacred speech, thought, spoken or sung to act on the mind. Grammatically the word joins the root man, "to think", and the suffix -tra, which makes names of instruments: an instrument of thought. Commentators also play on a traditional etymology, mananāt trāyate, "it protects through reflection". That second reading is devotional rather than historical, but it says how India has always regarded mantra: a protection for the one who repeats it with attention.
Where mantras come from
Not all mantras are the same age, nor used in the same way. Knowing the family of a mantra tells you how the tradition treats it.
| Family | Language and form | Examples |
|---|---|---|
| Vedic | verses of the Vedas, chanted with pitch accents | Gāyatrī (Ṛgveda 3.62.10), Mahāmṛtyuñjaya (Ṛgveda 7.59.12) |
| Upanishadic | the sacred syllable and the peace chants | Om, pūrṇam adaḥ, asato mā |
| Devotional | names of deities with namaḥ, homage | Om namaḥ śivāya, oṃ namo nārāyaṇāya |
| Tantric | short seed syllables (bīja), usually given in initiation | LAṂ, VAṂ, RAṂ of the chakras |
Some verses heard in yoga classes, such as lokāḥ samastāḥ sukhino bhavantu, "may all beings everywhere be happy", are much later and of uncertain source. They are sincere and beautiful; they are simply not Vedic.
Three mantras from the oldest texts
Asato mā: from the unreal to the real
The Bṛhadāraṇyaka Upaniṣad (1.3.28) gives three lines to be murmured (japet, the verb of japa) while the priest begins a Vedic chant; Śaṅkara's commentary says this japa belongs to the patron of the sacrifice (yajamāna):
असतो मा सद्गमय । तमसो मा ज्योतिर्गमय । मृत्योर्मामृतं गमय ॥
asato mā sad gamaya | tamaso mā jyotir gamaya | mṛtyor māmṛtaṃ gamaya ||
From the unreal lead me to the real. From darkness lead me to light. From death lead me to immortality.
The Upaniṣad itself explains: the unreal and darkness are death; the real and light are the deathless.
Pūrṇam adaḥ: the peace chant of fullness
पूर्णमदः पूर्णमिदं पूर्णात्पूर्णमुदच्यते । पूर्णस्य पूर्णमादाय पूर्णमेवावशिष्यते ॥
pūrṇam adaḥ pūrṇam idaṃ pūrṇāt pūrṇam udacyate | pūrṇasya pūrṇam ādāya pūrṇam evāvaśiṣyate ||
That is full, this is full. From the full, the full comes forth. Take the full from the full, and the full remains.
It is recited before the study of several Upanishads, followed by oṃ śāntiḥ śāntiḥ śāntiḥ, "peace, peace, peace".
Om, the first of all
The syllable Om opens and closes Vedic recitation and almost every mantra. Patañjali makes its repetition a complete practice:
तस्य वाचकः प्रणवः । तज्जपस्तदर्थभावनम् ॥
tasya vācakaḥ praṇavaḥ | taj-japas tad-artha-bhāvanam ||
Its word is the praṇava, Om. Its repetition, and dwelling on its meaning.
Two words sum up all mantra practice: japa, repetition, and bhāvana, cultivating the meaning.
Public mantras and initiation
In many Indian lineages a mantra is not learned from a book but received from a teacher (guru) in an initiation (dīkṣā): the teacher whispers it with instructions on when and how many times to repeat it. This holds for personal mantras in Vaiṣṇava, Śaiva and Śākta lineages, for most tantric seed syllables and, in orthodox Brahmanical practice, for the Gāyatrī, imparted at the sacred thread ceremony (upanayana).
Other mantras are public by nature: Om, the peace chants, the divine names sung in kirtan. On each mantra page we say how the tradition treats it. Where a mantra is traditionally reserved, we present its text and meaning for study, as countless printed books in India do, and leave the rest to you and, ideally, to a teacher.
Pronouncing Sanskrit correctly
In the tradition a mispronounced mantra is a changed mantra. Five rules cover most mistakes:
- Short and long vowels. a is short, as in but; ā is long, as in father. In namaḥ śivāya: "nuh-muh shi-vaa-yuh".
- ś and ṣ are both "sh" sounds; c is always "ch" (pracodayāt = pra-cho-da-yaat).
- Aspirates (bh, dh, th, kh) are a consonant followed by a breath: dhīmahi is never an English "th".
- ḥ (visarga) is a light breath echoing the vowel: namaḥ ≈ "na-ma-ha", very softly.
- ṃ (anusvāra) nasalises: oṃ ends with the lips closed, humming.
Vedic mantras are also chanted with three pitch accents. They are learned by ear from a trained chanter, not from a page.
How mantras are practised
The repetition of a mantra is called जप (japa). Teachers commonly distinguish three ways: aloud (vācika), murmured with only the lips moving (upāṃśu), and mental (mānasa), the quieter forms being considered the more inward. A mala of 108 beads is used to count. The step-by-step practice is on the page mantra meditation and japa.
Good to know
Begin with one mantra only, for example Om or oṃ namaḥ śivāya, at the same time each day, eleven repetitions aloud, then a minute of silence. Change only if a teacher advises you to.
Questions people ask
What is the most powerful mantra?
The tradition does not rank them that way. Om is called the root of all mantras, and the Gāyatrī holds the central place in Vedic daily practice; a mantra received from one's teacher is, for that person, the most important.
Can I chant a mantra without initiation?
Many mantras are public: Om, the peace chants, the divine names of kirtan. Some, like personal mantras and most tantric seed syllables, are traditionally received from a teacher. Each mantra page says which.
Do I need to understand the words?
Patañjali pairs repetition with dwelling on the meaning (Yoga Sutra 1.28). Knowing the word-by-word sense turns repetition into meditation.
How many times should a mantra be chanted?
Traditional counts are 3, 11, 21 or 108, the number of beads on a japa mala. Regularity matters more than quantity.
