Om Tat Sat is the threefold name of Brahman, spoken to make a flawed sacred act whole.
After sorting every act into pure, restless, and dull, Krishna gives a seeker something to do when even a sincere effort falls short: speak the name at the very origin of sacred life, and let it gather the deficiency back.
Om, Tat, Sat: this threefold word is remembered as the name of Brahman. By it, in the beginning of creation, the priests, the scriptures, and the sacrifices were set in place.
The reading read whole, as one unhurried piece
Where it stands
You have just been told to take up the pure act and let go of the restless and the dull. But sorting your acts this finely can breed a new worry: what if, in practice, almost nothing you do is quite pure enough? Krishna answers that worry directly here.
The teaching
Brahman carries a threefold name: Om, Tat, Sat. Those who know Brahman remember it and hand it down; each of the three words is, on its own, already a complete name of the Absolute, established by its own place in scripture, much the way Om alone already stands whole as a name. Sacrifice, austerity, and gift aim at a fruit you cannot see, so a missing part, a wrong condition, a wandering attention, could keep that unseen fruit from arising even in a sincere, largely pure effort. Here is what to do about that. Speak this name, Om Tat Sat, over the act, and what was lacking is gathered back. You can trust the name's power because of where it stood at the very beginning: by it, of old, the priests, the scriptures, and the sacrifices themselves were brought forth. What founded all sacred action can surely mend one sacred act now.
The doubt that rises
How can three spoken words actually repair a flawed action? Is this a real remedy, or only a comforting story told to the anxious performer?
Where the paths divide
Read as praise of the name, kept close to the text.
Shankara stays narrow here: this is praise of the threefold name, shown worthy of trust because of its place at the very origin of sacred life. He does not himself turn this into a formal ritual rule; that further step, reading an actual injunction into the praise, is taken by later Advaita voices such as Madhusudana, who reason from the name's founding power to its remedial power now.
Read as three words with three distinct offices.
Ramanuja will not let you treat Om, tat, and sat as interchangeable. Om belongs at the very start of carrying out the Vedic act; tat and sat are designators that hold the act worthy of honor. Brahman, for him, is the Veda, so the sacrifice itself joins the word sat. And every part of this, the brahmins, the Vedas, the sacrifices, was set forth of old by the Lord in his own voice: by Me alone.
Read as a lesson in what the Lord does and does not create.
Madhva insists Brahman here is the supreme Vishnu, full and complete, and draws a distinction you should hold onto carefully: the Veda is beginningless and authorless in its own nature, so the Lord only manifests it for the worship of the Self, while the brahmins are genuinely created. Ordained, on his reading, has to carry both senses in the same breath.
Read as instruction for one already past the three gunas.
Abhinavagupta ties this verse to those whose wisdom has already crossed beyond sattva, rajas, and tamas. Om bids continued engagement with scripture while embodied; tat, a bare pronoun, teaches aiming at no fixed fruit at all; sat marks the Real. Act simply because it is to be done, with no fixed fruit in view, and no bondage follows. He also offers, clearly as his own further step, a second reading in which the three words trace peace, the play of will, and an ever-full fullness.
Read as the name's power to redeem a flawed offering.
Sridhara names the worry directly: reasoned out, nearly all sacrifice, austerity, and gift is rooted somewhat in passion or dullness, so the whole labor can seem wasted. His answer is that each of the three words is independently a name of Brahman, and speaking them over an action draws whatever was rajasic or tamasic in it back toward being, toward sat. He calls this the chapter's healing turn.
Read as an argument from origin to remedy.
Madhusudana gives the fullest account of the mechanism. Sacrifice, austerity, and gift serve unseen ends, so a missing part could void their fruit even for a sincere performer; the Lord, out of compassion, supplies a general mending, uttering his own name. He reads an implied injunction into the praise and grounds the name's power causally: it was the very tool by which the priesthood and its sacrifices were founded in the first place, so it can mend a single lapse now.
All six readings agree that the threefold name has real power to mend a flawed act, and all trace that power back to its place at the very origin of sacred life. They do not agree on the mechanism. Is this a formal rule of expiation, quietly implied in praise, as the Advaita line reads it? A matter of each word's distinct grammatical office, as Ramanuja holds? A manifesting, not a creating, of an authorless Veda, as Madhva insists? Or, on Abhinavagupta's reading, an instruction that dissolves the very question of fruit for one already past the three qualities? This page does not choose among them.
A question to carry
The next time an act of yours, however sincere, feels incomplete, can you speak its intention back toward its source rather than filing the whole effort away as wasted?
Where this teaching travels
Verses that sit near this one, each going its own way; follow whichever calls you.
When your own worship or your giving comes up short, a part missing, the time wrong, the attention astray, do not count it lost. Speak the name of what it was always offered to, and let what your hands could not finish be gathered whole elsewhere.

It closes the long teaching on the three gunas by naming the remedy for the fear that ordinary heedlessness might void a sattvic act's unseen fruit.
Where they agreethe convergence
Across schools and centuries the commentators come to the same ground. These are the points they share, and the voices that hold each one.
Om, Tat, Sat is remembered as the threefold name of Brahman; each single word is already, on its own scriptural warrant, one complete name of the Absolute.

All six readings agree on the plain sense: Om, Tat, Sat is a threefold name of Brahman, handed down by those who know Brahman, and each single word is itself a complete name of the Absolute drawn from its own place in scripture, the way Om alone already stands whole as a name.
The verse answers a real fear: that a sincere but imperfect act of sacrifice, austerity, or gift might lose its whole unseen fruit through some missing part.

Most of the commentators read the verse against a fear left over from the previous teaching: having just sorted food, sacrifice, austerity, and gift into pure, restless, and dull, a sincere performer may worry that some missing part or wrong condition voids the unseen fruit of even a sattvic act, so that the whole labor seems wasted.
The remedy is not repetition or abandonment of the act, but speaking the name over it, so its deficiency is gathered back toward what founded sacred action itself.

The remedy the verse supplies, on this shared reading, is uttering the name itself over the deed. Speaking Om Tat Sat upon the act makes good whatever was lacking, gathering an imperfect offering back to the source from which sacred action itself first came.
By this very name, at the very beginning, the priests, the scriptures, and the sacrifices were themselves brought into being, of old.

The schools part on the mechanism, an implied rule, a set of distinct word-offices, a manifesting of an authorless Veda, or a dissolving of the question of fruit, but not on the remedy's direction: back toward the source.

Every reading treats ordaining as an act with an agent rather than a bare impersonal happening, though the commentators differ sharply on who or what that agent finally is and on the precise relation between the name, the Veda, and Brahman.
This is the shared ground; it can be carried as it is. Below is where they differ.
Where they differthe divergence
Viśiṣṭādvaita, in their fuller words
Ramanuja distinguishes how each word attaches: Om as a subsidiary at the very outset of Vedic action, tat and sat as designators holding the act worthy of honor, with Brahman identified as the Veda so that sacrifice itself joins the word sat. He confirms the verse as the formula that cures a limb-defect, ordained of old by the Lord in his own first person, by Me alone.
Dvaita, in their fuller words
Madhva insists Brahman here is the supreme Vishnu, not any lesser power, and draws a sharp distinction between manifesting and creating: the Veda is beginningless and authorless in its own nature, only made manifest for the worship of the Self, while the brahmins are genuinely created. Ordained, on his reading, must carry both senses at once.
A modern reading, in their fuller words
Madhusudana gives the most technical account of the mechanism: an injunction is read into the praise on the model of established interpretive rules, supported by the recollection that heedless lapses in ritual are made whole by remembering Vishnu, and traced causally to the name's having been the very tool by which Prajapati enjoined the sacrifices in the first place.
A few questions to carry
These ask for understanding, not recall; each answer is settled by the commentary itself.
For a second sitting
Carry this with youwhat stays
Bring to mind one act you carried out with real intent but felt fell short somewhere, a distracted prayer, a gift given without quite the right spirit, a promise kept only partly. Rather than filing it away as wasted, try speaking its intention back toward its source, quietly, as this verse teaches: not to erase the falling-short, but to let it be gathered up by something larger than your own effort.
When your own worship or giving feels incomplete, do not count it wasted. Speak the name of what it was always offered to, and let what was lacking in your hands be gathered whole.

Divergence
Advaita Vedānta
Shankara keeps the verse's own work narrow: it is praise of the threefold name, nothing more elaborate, showing the name's worth by its place at the very origin of sacred life. He does not himself press the expiation-reading into a formal injunction, letting the verse rest as an honoring of the name that the surrounding chapter's argument can then draw on.

A Seeker Asks
If a name spoken over a flawed action can make it whole, isn't that just wishful thinking dressed up as scripture?
The commentators do not treat the name as a magic word independent of understanding. Sridhara and Madhusudana both read it as drawing the act back to the very source from which sacred action first came, an intelligible return, not an arbitrary spell.
Śrīdhara Svāmī · Madhusūdana Sarasvatī
The reasoning offered is from cause to effect, not from superstition: what gave rise to all sacrifice, brahmins, and Vedas at the very beginning can reasonably be trusted to mend the deficiency of one sacrifice now. That is an argument, even if you are free to weigh it.
Śaṅkarācārya · Madhusūdana Sarasvatī
And Madhva's insistence that Brahman here is Vishnu, worshipped through the name, reframes the whole question: this is not a claim that syllables have power in themselves, but that sincere address to the Real, however imperfectly voiced, is heard by what the address is aimed at.
