To know Krishna as the Supreme Person, without confusion, already is to worship him completely.
This verse closes the chapter's long argument about who Krishna is by naming its fruit. Knowing him rightly, it says, is not a private achievement kept in the mind; it shows itself, of its own accord, as a whole life given over to him.
Whoever knows me this way, free of confusion, as the Supreme Person, that one knows everything worth knowing and gives themselves to me completely.
The reading read whole, as one unhurried piece
Where it stands
Krishna has just told Arjuna who he is: the Supreme Person, standing higher than both the perishable multitude of beings and the imperishable witness behind them. Now he tells him what it means, in an actual life, to have understood that.
The teaching
Know Krishna this way, exactly as he has just described himself, and one confusion falls away: the confusion that takes him for merely a remarkable man, or takes the self for the body and its belongings. Nothing elaborate is asked beyond the removal of that single mistake. Once it is gone, the knower is called sarva-vit, knower of all, and the claim is not that such a person has read every book. It is that they have grasped the one root in which everything else stands, so that knowing it is, in the sense that matters, knowing all. And this knowing does not stay folded quietly inside the mind. It shows itself, almost as a matter of course, as worship offered with the whole being, in every state and manner a life can take. Where the sources speak with confidence, this page follows them; where a source, like the fragment attributed to Madhva, offers little beyond a restatement of the verse itself, that thinness is worth naming plainly rather than dressed up as a fuller teaching it does not, in fact, give us.
The doubt that rises
How does knowing one thing make a person the knower of all, when people who have studied every scripture can still, on this same verse's terms, be called deluded?
Where the paths divide
A brief, unelaborated statement of the verse's own claim.
What survives here is short: the undeluded knower of the Purushottama becomes all-knowing, and knowledge and worship meet at the supreme. No extended argument is drawn out for why this is so; the comment lets the fruit stand on its own, as if the chapter's earlier reasoning has already carried the weight, and this verse only needs to name what it has produced.
For the devotee who stays distinct even in the closest knowing of the Lord.
Knowing the Lord here means knowing him as distinct from both the perishable and imperishable persons, marked by his undecaying nature and by his pervading, upholding lordship. Such a knower is called knower of all not by becoming the Self of all but because to know the one who pervades everything is already to know all he pervades. And there is a further note, unusual and tender: this knowing and worship bring a joy to the Lord himself, so that the verse reads, on this account, as his own delight in being rightly known.
Honesty about a thin source, rather than an invented elaboration.
What is actually preserved here is little more than the verse's own words repeated back. No distinctive argument about dependence, gradation among souls, or the Lord's absolute independence survives in this fragment, though such themes are well known from the school elsewhere. A fuller Dvaita reading can be offered, but only if it is clearly marked as a conditional extension of the wider school's principles, not presented as this comment's own settled teaching.
For the one who sees every state of being as already the Lord.
Here the knower worships nothing but the one truth of Brahman that holds all things within it, because he sees all things as made of that truth. Every state, whether shaped as form, as action, or as knowledge, is already the Lord being worshipped. The comment's own appended hymn presses the point further: there is no portion of time left empty of praise, since nothing, rightly seen, was ever separate from the divine to begin with.
For the seeker in whom knowing and serving are a single act.
The right knowing of the supreme Person just is the all-modes service of him. Nothing is left over once the Lord is truly known, except the giving of oneself to him in every state and manner. This reading declines to treat knowledge and devotion as two separate stations on a path a seeker must travel between; they are named here as one and the same accomplishment.
Read as the fulfillment of two earlier promises in the text.
This verse is where two earlier claims of the Gita are finally made good: that devotion carried past the three gunas fits a person for the state of Brahman, and that the Lord himself is Brahman's own footing. The devotional verse appended in support, praising the Lord's radiance and his repeated descent to lift the world's burden, functions as a seal binding this philosophical claim to a felt, lived devotion.
The readings part on the mechanism behind the title knower of all. Is it that the knower becomes the very Self of all, so that one knowing simply is all knowing? Or does the knower remain distinct from the Lord, called all-knowing only because the Lord he knows pervades everything else? And where a source is thin, as with the fragment on Madhva, how much may honestly be extended from the wider school before it stops being that source's own teaching? None of this is settled here, and it should not be settled falsely.
A question to carry
Where does your own attention rest today without your telling it to, and would you call that resting worship if you looked at it plainly?
Where this teaching travels
Verses that sit near this one, each going its own way; follow whichever calls you.
May the one confusion that keeps knowing and giving apart fall away, so that to know him truly and to worship him with your whole being are found, quietly, to have already been the same thing.

Krishna has just named himself the Supreme Person, beyond both the perishable and the imperishable; here he states what it means, in a life, to have actually understood that.
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.
The knowing this verse praises is exact, not vague: it is the recognition of Krishna as the Supreme Person just described, not a general feeling of reverence.
Across Advaita, Viśiṣṭādvaita, BhaktiŚaṅkara · Rāmānuja · Śrīdhara · MadhusūdanaIn Śaṅkara, Rāmānuja, and 2 others’ words
The verse names the fruit of everything the chapter has just argued: the one who knows Krishna 'thus,' exactly as described a moment ago, standing above both the perishable and the imperishable, becomes the knower of all and gives his whole being in worship. The word 'thus' carries real weight; it points back to a precise identification, not a vague feeling of reverence.
Only one confusion needs to fall away, taking Krishna for merely a man or the self for the body; remove it, and the knowing this verse names stands clear.
Across Advaita, BhaktiŚaṅkara · Śrīdhara · MadhusūdanaIn Śaṅkara, Śrīdhara, and 1 others’ words
Being undeluded is read, across the readings that address it, as the absence of one specific error: mistaking Krishna for merely a remarkable man, or mistaking the self for the body and its belongings. Remove that single confusion and the knowing this verse praises stands clear on its own.
To be called knower of all is to have grasped the root in which everything rests, not to have memorized every fact there is.
Across Viśiṣṭādvaita, Bhakti, AdvaitaRāmānuja · Śrīdhara · MadhusūdanaIn Rāmānuja, Śrīdhara, and 1 others’ words
Such a knower earns the striking title sarva-vit, knower of all, and though the readings differ on the mechanism, they agree on the shape of the claim: to know the Supreme rightly is somehow to have grasped everything worth knowing, so that further learning adds nothing essential once this one recognition is secure.
This knowing does not sit still in the mind; it shows itself as worship offered with the whole being, in every state and manner of a life.
Across Viśiṣṭādvaita, Kashmir Śaiva, Bhakti, AdvaitaRāmānuja · Abhinavagupta · Śrīdhara · MadhusūdanaIn Rāmānuja, Abhinavagupta, and 2 others’ words
Knowledge and worship are held together rather than treated as two separate achievements. Whatever the school, the right knowing of the Supreme is not left to sit inertly in the intellect; it issues, as though by its own nature, in worship offered with the whole being, in every state and manner of a person's life.
Where the sources themselves are thin, as with the fragment attributed to Madhva, the honest path names that thinness rather than inventing a fuller doctrine in the master's voice.
Across DvaitaMadhvaIn Madhva’s words
Where the source material is thin, as with the fragment attributed to Madhva, the honest reading declines to manufacture a full doctrine and instead notes plainly what is and is not preserved, rather than presenting a guess as though it were the master's settled teaching.
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 reads the knowing as recognition of the Lord's distinctness from both the perishable and imperishable persons, marked by his undecaying nature and his pervading, upholding lordship. Sarva-vit follows not from becoming the all-Self but from knowing the one who pervades all and is the means to reach all; strikingly, this knowing and worship are said to bring a joy to the Lord himself, so the verse becomes his own praise of being rightly known.
Dvaita, in their fuller words
The material actually on file here is a bare restatement of the verse, offering no distinctive Dvaita elaboration of dependence or gradation. Any fuller Dvaita reading, of a self whose very capacity to know and worship is itself granted by the Lord's sanction, would have to be flagged explicitly as a conditional extension of the wider school's principles rather than attributed to this fragment.
Bhakti, in their fuller words
Sridhara refuses to let knowledge and devotion stand as two separate stages. The right knowing of the supreme Person just is the all-modes service of him; nothing remains to be added once the Lord is truly known except the giving of oneself, so that metaphysical clarity and loving service are named as a single accomplishment.
A modern reading, in their fuller words
Madhusudana ties this verse back explicitly to two earlier statements, that devotion beyond the gunas fits one for Brahman, and that the Lord himself is Brahman's footing, reading 15.19 as where those two claims are finally made good. The devotional verse he appends, praising the Lord's radiance, functions as his own seal binding a philosophical argument to a lived, felt devotion.
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
Sit for a moment with the claim that knowing and worship are not two separate tasks. Notice where your attention keeps returning today, on its own, without effort. That is where your worship already is, whether or not you have named it that. The invitation of this verse is not to add a new practice on top of your day, but to let that same attention rest, finally, on what it was always straining toward.
May the one confusion that keeps you at a distance fall away, so that knowing and giving are no longer two different things you must still learn to join.

Madhusūdana Sarasvatī
A Seeker Asks
How can knowing one thing, Krishna as the Supreme Person, make me the knower of all, when people who have studied everything are still called deluded?
Because what is known here is not one fact among many but the root in which everything else stands. To know the root is to know, in essence, everything that grows from it; the claim is not that you have memorized every fact, but that the one thing needed to be free has been grasped.
Rāmānujācārya · Madhusūdana Sarasvatī
The line is drawn not at how much a person has studied but at whether one confusion remains: taking Krishna for merely a remarkable man, or taking the self for the body. Vast learning that keeps that confusion intact has missed the point; a simpler knowing that has released it has not.
Śaṅkarācārya · Madhusūdana Sarasvatī
The proof asked for is not an argument but a life: this knowing shows itself in worship offered with the whole being, in every state and manner. If the claim to know feels doubtful, the practical test is simply whether it has begun, of itself, to turn into that giving.
