God alone, by His own Self, knows Himself.

Arjuna gathers five names into a single breath, best of persons, bringer of beings, Lord of beings, God of gods, Lord of the world, and beneath them all he lays one confession: You alone, by Your own Self, know Yourself. All that praise names what He alone fully knows.

Sanskrit recitation by Swami Brahmānanda

Audio from the Gītā Supersite, IIT Kanpur

Arjuna's words of praise here seal an asymmetry already named, that only the Lord knows the Lord, and prepare the request that follows, that the Lord Himself name His glories, since no one else can supply the list.

Where they agreethe convergence

God alone knows Himself, by Himself, without any instrument or outside teaching; He is at once His own proof and His own knower.

Across schools and centuries the commentators come to the same ground. These are the points they share, and the voices that hold each one.

No creature stands at any vantage from which to measure Him; what He is, He alone knows, and He knows it by Himself.

In Śaṅkara, Madhusūdana, and 11 others’ words

Arjuna says that God alone, by Himself, knows Himself. The verse opens with 'svayam eva atmana atmanam vettha tvam,' which the commentators render as 'You alone, by Your own Self, know Yourself.' The point is not just that God knows a great deal, but that He is the only knower of His own nature, and He knows it without any outside instrument or teaching. No creature stands at a vantage point from which God could be measured, so He is both what is measured and the one who measures, His own proof and His own knower.

All beings come after Him, so none can reach back to know their origin in full; whoever knows Him receives that knowing from His side.

Across Advaita, Śuddhādvaita, BhaktiMadhusūdana · Ānandagiri · Puruṣottama · Viśvanātha · Baladeva
In Madhusūdana, Ānandagiri, and 3 others’ words

Several commentators explain why this self-knowledge is exclusive: God is the source and beginning of all beings, so the beings that come after Him cannot reach back to know their origin in full. Some add a softening: a rare devotee, perfected over many births and favored by God's own grace, can come to know God, but only because God Himself gives the very power of awareness by which He is known. Even such a one does not grasp how the seemingly impossible features of God (being unborn yet taking birth, and the rest) hold together. So the knowing always begins from God's side, never from the creature's own faculties.

Love here overflows into five names at once, and each name closes a gap the one before it leaves open.

Arjuna heaps up five names of address (vocatives) in a single verse, more than appear in any other verse of the Gita, and the commentators read this as an outpouring of love and reverence. The five are Purushottama (best of persons), bhuta-bhavana (bringer of beings into being), bhutesha (Lord of beings), deva-deva (God of gods), and jagat-pati (Lord of the world). Madhusudana, Vishvanatha, and Baladeva read the last four as a tight chain of objections answered: a father may not rule, so 'Lord of beings'; a ruler may not be worthy of worship, so 'God of gods'; one worthy of worship may not protect, so 'Lord of the world.' Each name closes a gap the previous one leaves open, building the full case for calling God the very best of persons.

He brings all beings into being, rules them, receives the worship of the gods themselves, and guards the world, teaching it what helps and harms.

In Śaṅkara, Madhusūdana, and 9 others’ words

The commentators unpack the four descriptive names as a portrait of God's complete relation to the world. As bhuta-bhavana He produces and begets all beings; as bhutesha He governs and controls them; as deva-deva He is worthy of worship even by the gods who are themselves worshipped; and as jagat-pati He protects and sustains the whole world. Several add that He guards the world by giving the Veda that teaches what is beneficial and what is harmful, so His protection works through instruction, not force alone. The cumulative picture is of a God who is at once father, ruler, supreme object of worship, and guardian of all that exists.

This is the shared ground; it can be carried as it is. Below is where they differ.

The question they answer differently
If God alone knows Himself, what exactly does He know, and how can anyone else ever come to know Him?
The traditional commentators
Advaita VedāntaŚaṅkara, Madhusūdana, Dhanapati
By Himself God knows both the formless Self that no cognition can reach and the Lord arrayed in knowledge, strength, and sovereignty.
Read as spanning God's unconditioned and conditioned aspects.
Advaita Vedānta, in their fuller words

The Advaita commentators draw a sharp distinction between God's two aspects, the unconditioned (nirguna) and the conditioned (saguna), and say He knows both by Himself. The unconditioned aspect is the inmost Self, beyond being an object of any cognition; the conditioned aspect is endowed with unsurpassed knowledge, lordship, strength, and the other powers. On this reading the deepest knowing is of the formless Self that no faculty can reach, while the name 'best of persons' itself points to His power of knowing that objectless Self. The creating, ruling, and protecting names then describe the saguna side, the Lord as maker of the world.

Only the Lord knows the Lord, for quality upon quality His nature outruns the knowing of every creature, even the gods.
Read as the ground of Arjuna's coming request for God's own glories.
Viśiṣṭādvaita, in their fuller words

These commentators read the asymmetry of knowing as fixed by God's surpassing nature: only the Lord knows the Lord because His nature exceeds the cognitive reach of any creature. They stress His host of auspicious qualities, His beauty, and His gracious accessibility. Just as a human surpasses beasts, birds, and reptiles by such qualities, so God surpasses even the gods by quality after quality. One source ties this directly to the coming request for God's glories (vibhutis): Arjuna asks God to name them precisely because no creature could supply the list, since only God knows His own glories in their truth.

The Lord is the supreme Brahman, great and making all full, who by His own might becomes manifold and so pervades all.
Read at the level of the words themselves, with grammar and scripture as guides.
Dvaita, in their fuller words

This commentator works at the level of the words 'Brahman' and 'all-pervading' (vibhu), explaining each in order with grammatical and scriptural authority. 'Brahman' is the supreme reality, so called because it is great, full, and makes others full, fills them; the word is derived from the root 'brh.' The Lord, though other than the deity Brahma, is the supreme Brahman because He became manifold, of many forms. His first, seminal form is the bestower of seed; being capable of mighty becoming He is 'lord' (prabhu), and having become manifold He is 'all-pervading.' A scriptural text on God's desire to become many is cited to support this reading of His self-multiplication.

ŚuddhādvaitaVallabha, Puruṣottama
God knows His own form by His own free will, and the devotee knows Him only through a gifted share of that self-awareness.
Śuddhādvaita, in their fuller words

These commentators keep the focus on God's self-disclosure by His own will. Vallabha keeps the gloss short: the verse seals the asymmetry that an earlier verse named and prepares the request for God's glories, since no one else can supply the catalogue, the matter being wholly God's own self-revelation. Purushottama adds that God knows His own form of His own free will, not impelled by anything; he cites a Purana that this One is fit to be contemplated by none, and explains that the devotee comes to know God only because God, by His own grace, gives him a portion of the very power of self-awareness, which is why an earlier verse promised to bestow the yoga of understanding.

No one stands anywhere to take God's measure; His compassion alone brings His devotees to the sight of His real form.
For devotees, whether among the gods or among the demons.
Bhakti, in their fuller words

The devotional commentators emphasize that God is His own measure and His own measurer at once, with no creature standing at a vantage to measure Him. Two of them add that God's devotees, even among the gods or among demons, do come to know His real form, though they still cannot grasp the manner of His unborn-yet-born nature, and they know even this only because His boundless compassion makes Him the protector of beings like the speaker himself. Jnaneshwar offers vivid images for the impossibility of knowing God by one's own power: outstripping the mind in speed, clasping the wind in one's arms, or swimming the ocean of the primeval void; only God's own infinite knowledge equals the task, yet God also has the power of His word to make others realize Him.

God's knowing of Himself needs no instrument at all, and the soul, being His part, may know its own nature the same way.
Read as a pointer for the soul's own self-knowledge.
A modern reading, in their fuller words

The modern commentators largely consolidate the shared reading. Sivananda explains that God is called best of persons because He assumes the four forms named, and that He is God of gods because even Indra and the other gods worship Him, and Lord of the world because He protects and guides people through the Veda. Ramsukhdas develops a distinct practical turn: God knows Himself with no worldly instrument, no arising of any mental movement or inquiry, no inner or outer means, because His knowing is independent of any instrument. He then applies this directly to the individual soul, who is a part of God: just as God knows Himself by Himself, so the soul ought to know its own real nature by itself alone, since that self-knowledge too is independent of the senses, mind, and intellect.

A few questions to carry

These ask for understanding, not recall; each answer is settled by the commentary itself.

1
When Arjuna says that You alone know Yourself by Yourself, what is he confessing about God's knowing?
2
Yet a rare devotee, perfected over many births, does come to know God. What makes that knowing possible?
3
Within Śaṅkara's school, what is the deepest thing God knows when He knows Himself by Himself?
4
Rāmsukhdās turns this praise toward your own life. What does God's instrument-free self-knowing mean for you?
For a second sitting2 more questions
5
Why can no creature, however exalted, come to know God's nature in full by its own powers?
6
For Rāmānuja's school, why must Arjuna ask God Himself to recount the divine glories?

Carry this with youwhat stays

Ramsukhdas turns this verse from a statement about God into a pointer for your own inner life. God knows Himself by Himself, with no instrument, no stirring of thought, no searching inquiry; His self-knowing simply is, needing nothing borrowed. Because you are a part of that same God, your knowing of your own true nature works the same way. It does not finally come through the senses, the mind, or the intellect, which can only reach outward objects. Your own being is already self-evident to itself. So the invitation here is to stop trying to grasp your deepest self as if it were one more object to be examined, and instead rest in the awareness that is already, effortlessly, aware of itself.

The awareness in you already knows itself, the way He knows Himself, without reaching for anything.

A Seeker Asks

If only God can know God, and even the rare devotee knows Him solely by God's gift, what room is left for my own effort to know the divine?

Start by accepting what the verse actually claims: God alone, by Himself, knows Himself, with no outside instrument or teaching. This is not a discouragement of your effort but a description of where the deepest knowing comes from. Since God is the source from which all beings arise, the faculties that came after Him cannot reach back to net their own origin, so the knowing must begin from His side.

Śaṅkarācārya · Rāmānujācārya · Vedānta Deśika · Swami Ramsukhdas

Yet the commentators do leave real room for you. A rare devotee, refined over many births and favored by grace, does come to know God, and this happens because God Himself bestows the very power of awareness by which He is known. So your effort is not wasted; it is the readiness that opens you to receive what only God can give, and even an earlier verse promised that He would grant the yoga of understanding.

Śrī Ānandagiri · Madhusūdana Sarasvatī · Śrī Puruṣottama

There is also a thread you can act on directly. Because you are a part of God, your own true nature is known the way God knows Himself, by itself and not through the senses, mind, or intellect. So rather than straining to seize the divine as an object, you can turn toward the self-evident awareness that is already aware of itself, and Jnaneshwar's images remind you that no feat of mind or speed will capture God, while God's own word still has the power to make you realize Him.
