Convergence
rishna is now describing the second of three kinds of jnana (knowledge), the rajasic. Rajasic means born of rajas, the guna (the strand of nature) of passion, motion, and restless activity. The mark of this knowledge is that it sees separateness. Looking across all beings, it perceives many distinct selves, of many different kinds, each cut off from the others. Where the previous verse's sattvic knowledge sees one undivided being present in all beings, this knowledge fastens on the variety alone. The little word 'tu' ('but') is deliberate: it draws a sharp line between this knowledge and the sattvic knowledge just praised, signaling that they are alike only in the bare name 'jnana' and otherwise opposite in what they see.

The separateness is described in layers, and the commentators are careful that this is not mere repetition. First the beings are seen as 'nana-bhavan', many distinct natures (god, human, animal, bird, plant, and the rest), set apart by their very kind. Then within a single kind they are still sorted into 'prithag-vidhan', various sub-types, distinguished by such marks as happy and sorrowful, fair and tall, big and small. So the rajasic mind divides first across the kinds and then again inside each kind, multiplying distinctions at every level rather than resting in any underlying sameness.

Several commentators stress that the difference grasped here is not merely bodily but metaphysical: this knowledge takes the selves themselves to be genuinely many. It does not just notice that bodies differ; it concludes that there is a true plurality of distinct selves or knowers (kshetrajnas), one cut off from another. This is precisely what makes it rajasic rather than simply observant. The error lies in mistaking the diversity of forms for a diversity in the underlying reality, and in identifying each being with its body, mind, senses, and life-breath instead of seeing the one changeless self that stands within them all.
Śrīdhara Svāmī · Madhusūdana Sarasvatī · Śrī Nīlakaṇṭha · Swami Ramsukhdas
Because it is grounded in passion and motion, this knowledge has the power to deceive. It throws a veil of separateness over the manifold creation and so hides the unity that is actually there, leading even an otherwise wise person astray. The one who has it sees diversity everywhere and beholds only the many; the perception of oneness is lost. A small grammatical point underlies the verse: knowledge cannot literally be the agent that 'knows', so the line means the knowledge by which a person knows. Agency belongs to the knower, and the instrument is spoken of as if it acted, as in the idiom 'the firewood cooks'.

Divergence
Advaita Vedānta
For these commentators the rajasic knowledge is the cognition of the non-dual seeker's opponent: the 'bad logician' who holds difference to be ultimately real. One spells this out as the unfounded fivefold difference: the mutual difference among selves, the difference of selves from the Lord, the difference of both from insentient matter, and the mutual difference within insentient matter. That whole structure of real, irreducible difference is, on this reading, exactly what rajasic knowledge clings to, since the one undivided reality is in truth differenceless. One also takes up an objection, that some dualistic views are themselves correct and sattvic, and answers that the knowledge which sees separate selves body after body is rajasic, and that naming both the separateness and the manifold kinds is not redundant but a real two-step division.

Viśiṣṭādvaita
These commentators read the verse without condemning plurality as such, since for them difference among beings is real. The fault of rajasic knowledge is rather a one-sidedness: it grasps only the variety and misses the unity. One frames the multiplicity concretely as the states of self seen in the brahmin-form and the rest, sorted by such marks as fair and tall, and as fit for connection with results in the hour when one is qualified for action, locating this knowledge in the active, fruit-seeking life. The mark, the other says plainly, is seeing the many as separate while the unity is missed; only the variety is grasped.
Rāmānujācārya · Vedānta Deśika
Śuddhādvaita
These commentators set rajasic knowledge against the sattvic vision of the Lord's single play (lila). The sattvic eye sees one divine sport running through all forms; the rajasic eye, 'devoid of the recognition of the single play', sees only many jivas of differing kinds with differing longings, scattered through the world as so many distinct natures, dharmas, and ends. So defined, the rajasic knower remains caught within the multiplicity of prakriti (nature) and its kinds, unable to abide in the one unaltering being that sattva discloses. This is the cognitive style, one says, of a mind in motion among the gunas, attached to distinctions; the other calls it knowledge marked by a scattered mind.
Vallabhācārya · Śrī Puruṣottama
Bhakti
These commentators dwell on how the rajasic knowledge actively obscures the underlying oneness. One insists the seeing is not of bodily difference alone but of a true metaphysical multiplicity of selves, and that fastening on this multiplicity is what makes the knowledge rajasic. The other develops the point through homely images: this knowledge is like a child who cannot see the gold hidden in the ornament, the fool who forgets the thread within the cloth, or one who loses sight of the canvas behind the painting. As the single fire seems many because of many fire-sticks, and the one moon seems many in many vessels of water, so this knowledge makes the one Self appear diverse through names and forms, displaying the play of waking, dream, and deep sleep as a kind of false infatuation outside the fortress of true Self-knowledge.
Śrīdhara Svāmī · Sant Jñāneśvar
Modern
These commentators give plain, practical restatements. One says simply that rajasic knowledge creates the impression that there are diverse principles in the various created things. Another stresses its deluding power: it wraps creation in a veil of separateness, so the one who holds it sees diversity everywhere and beholds only the many, losing the perception of unity. The third anchors the verse in the Gita's own definition of rajas as the embodiment of raga (attachment, 14.7): wherever attachment enters it produces liking for some and dislike for others, and so the rajasic knower treats devas, humans, animals, birds, insects, and plants, with all their variety of form, nature, name, and quality, as many different things in their very being, never seeing the one imperishable Self standing in them all, and lacking the discrimination between the inert and the conscious.

A Seeker Asks
If seeing the obvious differences between people, animals, and things is rajasic and faulty, am I supposed to pretend the diversity in front of my eyes isn't there?
No. The verse does not fault you for noticing variety; it faults a knowledge that grasps the variety and stops there, missing the unity. The error is one-sided seeing, taking the many as separate while the one is lost from view, not the bare fact of perceiving many forms.
Vedānta Deśika · Rāmānujācārya
What turns ordinary noticing into rajasic knowledge is fastening on the multiplicity as the real truth of things, concluding that the selves themselves are genuinely many and that each being simply is its body, mind, senses, and breath. That fastening, driven by passion and attachment, is what hides the one changeless Self present in all beings.
Śrīdhara Svāmī · Swami Ramsukhdas
And this is why it is called deluding rather than merely partial: the veil of separateness it throws over creation can mislead even the wise, so that one sees diversity everywhere and the perception of oneness is lost. The cure is not to deny the differences but to keep seeing through them to the single being they share, recovering the unity the rajasic eye drops.
Swami Sivananda · Sant Jñāneśvar
Contemplation
The teaching here is not that you must stop noticing differences, but that you should stop taking them as the final truth of a being. Watch how attachment works in your own seeing. As 14.7 puts it, rajas is the very nature of raga, of attachment, and wherever attachment slips in it splits the world into things you like and things you dislike. That splitting is the rajasic knowledge at work: it lets the variety of form, nature, name, and quality become the whole of what you see, so that a person, an animal, even a plant registers as just one more separate thing. The practice is to keep looking until, behind all that genuine variety of body, mind, senses, and life-breath, you begin to sense the one imperishable Self that stands in them all, and to recover the discrimination between what is inert and what is conscious. The differences remain; you simply stop letting them hide the single life within.
