Convergence
rjuna 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.

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.

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.

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.

Divergence
Advaita Vedānta
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.
Śaṅkarācārya · Madhusūdana Sarasvatī · Dhanapati Sūri · Śrī Ānandagiri
Viśiṣṭādvaita
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.
Rāmānujācārya · Vedānta Deśika
Dvaita
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.
Śrī Jayatīrtha
Śuddhādvaita
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.
Vallabhācārya · Śrī Puruṣottama
Bhakti
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.
Śrīdhara Svāmī · Śrīla Viśvanātha · Śrīla Baladeva · Sant Jñāneśvar
Modern
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 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.
Swami Ramsukhdas · Sant Jñāneśvar
Contemplation
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.
