Hari Om Tat Sat: Meaning, Translation, Pronunciation, and How to Chant
Share
People chant Hari Om Tat Sat as a devotional reminder of the divine and as a contemplation of reality beyond personal gain or attachment to results. Its words bring together Hari, a name associated with Vishnu or Krishna, and Om Tat Sat, a sacred formula from the Bhagavad Gita. You can repeat it quietly, aloud, or in a kirtan setting. There is no universally prescribed repetition count for this exact four-part form.
The Mantra
Translation
A cautious devotional rendering is: “Hari, the divine named by Om, That, and the Real.” A common interpretive rendering is: “Lord Hari is the absolute Reality; That is the Real.”
“Hari; Om; that; existent, real, or good.” The four elements are placed together without an expressed verb.
The Sanskrit does not literally state a complete sentence such as “Hari is the Supreme Truth.” Such translations add an implied “is” and a theological relationship between the terms. In Bhagavad Gita 17.23, Om, Tat, and Sat are presented as a threefold designation of Brahman. Sat has a wider range than English “truth”: it can indicate being, existence, reality, goodness, or what is commendable.
How to Pronounce the Mantra
ohm
tut
sut
| Mantra | Pronunciation | Notes |
|---|---|---|
| hariḥ | huh-ree(h) | Both vowels are short in Sanskrit. The final ḥ is visarga, a light voiceless release that may carry a faint echo of the preceding i before a pause. Many modern lineages chant “Hari Om” without an audible visarga. |
| oṃ | ohm | Use a long, pure o sound followed by a closed-lip m or nasal resonance. The scholarly transliteration of ॐ is oṃ. |
| tat | tut | The a is short, approximately the vowel in American English “cut.” Both t sounds are dental, with the tongue at or just behind the upper teeth. |
| sat | sut | Use a short Sanskrit a and a clear dental final t. It does not normally rhyme with English “cat.” |
Pronunciation Notes
- IAST transliteration is more precise than English phonetic spelling, which is only an approximation.
- Sanskrit does not use English-style lexical stress. Keep the syllables relatively even.
- The popular pronunciation “hah-ree om tut sut” is understandable, but it lengthens the first vowel of hari and leaves out the visarga.
- If you practice in a lineage that uses “Hari Om Tat Sat,” follow that lineage’s established pronunciation rather than adding an exaggerated “hariha.”
How to Chant Hari Om Tat Sat
Hari Om Tat Sat may be chanted as a short devotional repetition, used in meditation, or sung as part of a kirtan or yoga-practice closing.
Repeat the words at a comfortable, steady pace:
Hari Om Tat Sat
You may chant aloud, softly, or mentally. In a devotional approach, rest attention on Hari as a divine name and on Om Tat Sat as a designation of Brahman, or ultimate reality. In kirtan, follow the leader’s melody and repetition pattern.
- Japa, or repeated mantra recitation
- Mental repetition during meditation
- Soft or spoken recitation
- Meditative chanting
- Kirtan or sankirtan
- A closing invocation for yoga or spiritual activities
- Devotional invocation
No universally authoritative repetition count is established for the exact four-part formula. Bhagavad Gita 17.23 - 27 explains the significance of Om, Tat, and Sat but does not prescribe chanting Hari Om Tat Sat three times or 108 times. If you use a customary japa count, treat it as a personal or lineage practice rather than a scriptural requirement.
A mala is optional if you adopt the phrase for japa. No reliable source in this research prescribes a particular mala count for Hari Om Tat Sat.
The phrase is publicly printed and taught by modern Hindu yoga institutions, and no general initiation requirement was found for ordinary japa, meditation, kirtan, or yoga-class use. Formal ritual or lineage-specific uses may have their own guidance.

Word-by-Word Meaning
| Mantra | Basic Meaning | Grammar / Context |
|---|---|---|
| Hari / hariḥ | Hari, a divine name most commonly associated with Vishnu and Krishna | Hariḥ is masculine nominative singular. The formal vocative of hari is hare, so hariḥ is not grammatically a direct vocative equivalent to “O Hari.” In a mantra, it functions as a divine name or invocation. |
| Om / oṃ | The sacred syllable Om, also called pranava | Om is a sacred utterance treated as a quoted word or designation in Bhagavad Gita 17.23. It is not translated as an ordinary lexical noun. |
| Tat / tat | That | Tat is the neuter nominative or accusative singular of the demonstrative pronoun tad. In the Gita passage, it is a sacred designation linked with action performed without seeking its fruit. |
| Sat / sat | Being, existent, real, good, or commendable | Sat is the neuter nominative or accusative singular present participle of the Sanskrit verb “to be.” In the Gita, it is explained through existence, goodness, commendable action, and steadfastness in sacrifice, austerity, and charity. |
What Does Hari Om Tat Sat Mean?
Hari Om Tat Sat combines a personal divine name with a sacred formula associated with ultimate reality. For many practitioners, it offers language for devotion to Hari, often understood as Vishnu or Krishna, while also contemplating Brahman, the absolute reality named in the Bhagavad Gita.
At the most literal level, the phrase places together Hari, Om, “that,” and sat, meaning being, reality, goodness, or what is commendable. It does not contain an expressed verb. A translation such as “Hari is the absolute Reality” is therefore a devotional interpretation rather than a word-for-word sentence.
Bhagavad Gita 17.23 identifies Om Tat Sat as a threefold designation of Brahman. The verses that follow connect Om with beginning prescribed religious acts, Tat with acting without attachment to results, and Sat with reality, goodness, worthy action, and steadfast dedication.
In modern yoga and Vedanta settings, the expanded phrase is often understood as joining personal and impersonal language for the divine. That synthesis is meaningful within these traditions, but it is not grammatically stated by the four words alone.
Hari and the Threefold Designation of Brahman
Hari is a major divine name associated especially with Vishnu and Krishna. Traditional theology often connects the name with the Sanskrit root hṛ, “to take away or remove,” leading to devotional interpretations of Hari as one who removes sin, distress, or bondage. This is an interpretive epithet rather than the complete literal meaning of the name.
Om Tat Sat is identified in Bhagavad Gita 17.23 as a threefold designation of Brahman. Brahman is a central Sanskrit term for absolute reality in Vedantic traditions.
Adding Hari gives the phrase a personal devotional dimension not present in the Gita’s Om Tat Sat formula alone. Depending on the lineage, the combined phrase may identify Hari with Brahman, invoke Hari before affirming the Gita’s designation, or symbolize the unity of manifest and unmanifest reality.
Origin and History of the Mantra
The history has two distinct layers. Om Tat Sat is the scriptural formula found in Bhagavad Gita 17.23, with further explanation in verses 17.24 - 27. Hari Om Tat Sat is an expanded devotional and liturgical form whose exact origin and first use are unknown.
The earliest secure source identified for Om Tat Sat is Bhagavad Gita 17.23. The date of the Bhagavad Gita is disputed in academic scholarship, with estimates spanning the final centuries BCE and early centuries CE. Hindu tradition attributes the Gita to Vyasa within the Mahabharata and places it within a much earlier sacred chronology.
For the exact expanded phrase, an undated Bhagavad Gita manuscript catalogued by the National Library of Scotland contains a final colophon beginning hariḥ oṃ tat sad iti. Because it was catalogued from notes supplied in 1906, it shows that this manuscript witness was known by then, but it does not establish when the phrase was first used.
The earliest securely dated printed use located in this research is Swami Sivananda’s 1941 Bhakti and Sankirtan. Sivananda publications used Hari Om Tat Sat in devotional songs, sankirtan refrains, mantra lists, and conclusions. Swami Satyananda later described joining Hari Om and Om Tat Sat for his own yoga mission, an explanation that documents his lineage-specific use rather than the phrase’s first historical creation.
Today, the formula appears in Sivananda and Satyananda settings as a chant, japa formula, sign-off, greeting, and closing expression. These modern uses are documented institutional practices, not requirements set out in Bhagavad Gita 17.
Traditional Interpretations
In Shankara’s Advaita commentary on Bhagavad Gita 17.23 - 27, Om, Tat, and Sat are the threefold designation of Brahman. Their use relates prescribed religious acts to Brahman and, in that commentary tradition, may consecrate or address deficiencies in sacrificial and related actions.
In Ramanuja’s Sri Vaishnava commentary, Brahman in this passage can refer to the Veda, especially its ritual portion. Om accompanies the beginning of Vedic recitation and rites, while Tat and Sat indicate the honor, goodness, or auspicious character of the Veda and actions enjoined by it.
Swami Sivananda and the Divine Life tradition teach Om Tat Sat as an expression or symbol of Para Brahman, and present it as suitable for repetition. Their literature also lists Hari Om Tat Sat as a mantra of Lord Hari and uses it in devotional singing.
Swami Satyananda described Hari as manifest life and the universe, Om as unmanifest absolute reality, and Tat Sat as an affirmation of reality or truth. He identified this as his own understanding: a reminder that the seen and unseen, or manifestation and its source, are one. It should not be treated as the only traditional meaning.
Sanskrit and Grammar
Hari Om Tat Sat is a verbless formula. Hariḥ is the nominative singular form of hari, while hare would normally be the formal Sanskrit vocative. Om is a sacred syllable used as a name or designation. Tat is the neuter singular demonstrative pronoun meaning “that.”
Sat is the neuter singular present participle of the Sanskrit verb “to be.” It can function as “being,” “existent,” “real,” “good,” or “commendable.” Translating the phrase with “is” supplies a copula that is not expressed in the Sanskrit.
In Bhagavad Gita 17.23, the formula appears as oṃ tat sad iti. The change from sat to sad occurs because of external sandhi, a regular Sanskrit sound change: the final t is voiced before the vowel at the beginning of iti. Sad in this colophon form is not a separate word.
Variations of the Mantra
Om Tat Sat
This is the threefold formula found in Bhagavad Gita 17.23. It does not include Hari.
Hariḥ Om Tat Sat
This is the scholarly or grammatically explicit expanded form, retaining the visarga in hariḥ.
Hari Om Tat Sat
This is the common modern spelling and chant form. It usually omits the written and audible visarga after Hari.
Hariḥ Om Tat Sad Iti
This colophon form occurs when sat is followed continuously by iti. The final t changes to d through Sanskrit sandhi.
Sivananda kirtan arrangement
Hari Om Tat Sat
Sri Om Tat Sat
Siva Om Tat Sat Om
This musical and liturgical arrangement adds repetitions and other divine names for congregational singing. It is not the canonical wording of Bhagavad Gita 17.23.
How This Mantra Is Used Today
In modern Sivananda and Satyananda institutions, Hari Om Tat Sat is used as a devotional chant, japa formula, yoga-associated mantra, greeting or sign-off, and closing expression.
In a yoga class or retreat, you may hear it at the end of practice as a way of concluding an activity in a devotional or contemplative spirit. This use is institutionally documented, but it is not prescribed by Bhagavad Gita 17.23 - 27.
Recordings and kirtan arrangements may extend Om, repeat the phrase many times, add names such as Sri or Siva, or include prayers and peace chants. These are practice forms created for singing and communal participation, not additions required by the underlying scriptural formula.

Common Questions About Hari Om Tat Sat
Is Hari Om Tat Sat actually found in the Bhagavad Gita?
Bhagavad Gita 17.23 contains Om Tat Sat. Hari is a later devotional or liturgical addition and is not part of the verse’s threefold designation.
What is the literal meaning of Hari Om Tat Sat?
Literally, the formula places together Hari, Om, “that,” and “existent, real, or good.” It has no expressed verb, so sentence-like translations are interpretive.
Does sat mean truth?
Truth can be used in a broad interpretation, but sat more directly means being, existent, real, good, or commendable. Satya is the more specific Sanskrit word for truth or truthfulness.
Should it be written Hari or Harih?
The grammatically explicit Sanskrit form is hariḥ, written हरिः. Hari is the common modern spelling and chant form. The final ḥ represents visarga, not the English letter h.
Is Hari Om Tat Sat a Vedic mantra?
No secure Vedic source for the exact four-part phrase was located in this research. Its terms have older Vedic and Upanishadic histories, and Om Tat Sat occurs in the Bhagavad Gita, but the complete expanded phrase should not be called Vedic without qualification.
Is Hari Om Tat Sat a Vishnu mantra?
Hari commonly names Vishnu or Krishna, and Sivananda literature associates the expanded mantra with Lord Hari. The Om Tat Sat portion is a designation of Brahman interpreted across more than one Vedantic tradition.
Can Hari Om Tat Sat be chanted without initiation?
Modern Hindu yoga institutions publish and teach the phrase openly. No general initiation requirement was found for ordinary japa, meditation, kirtan, or yoga-class use, though specialized ritual settings may follow lineage rules.
How many times should Hari Om Tat Sat be repeated?
No universal or scripturally prescribed count was found for the exact phrase. Bhagavad Gita 17.23 - 27 does not require three, 108, or any other number of repetitions.
Why does sat sometimes appear as sad in a Gita colophon?
In Sanskrit, the final t of sat is voiced before the vowel beginning iti, producing sad iti. This is a regular external sandhi change, not a different word.
