Convergence
his verse is an announcement. Krishna tells Arjuna that he is about to sort three things into categories. The three things are jnana (knowledge), karma (action, here meaning the act that is performed, not a technical grammatical sense), and karta (the doer, the one who accomplishes the act). Each of these three is said to be of just three kinds. The dividing principle is the guna-bheda, the difference of the gunas, the three strands or qualities of nature: sattva (clarity, harmony), rajas (passion, restlessness), and tamas (dullness, inertia). So the verse promises a coming typology of nine items in all: three knowledges, three actions, three doers, one sattvic, one rajasic, one tamasic in each set.

The little word 'just' or 'only' (eva in tridhaiva, 'threefold only') is doing real work. It restricts the count. There is no fourth class beyond the three gunas; once you have sattvic, rajasic, and tamasic, the divisions are exhausted, because knowledge, action, and the doer are by their very nature woven of the gunas. Several commentators stress that this 'only' is meant to rule out any further variety and any rival scheme of classification.

The phrase guna-sankhyane, 'in the reckoning of the gunas,' points to the Sankhya system, the philosophy of Kapila, which counts and expounds the gunas by tracing the difference of their effects. Krishna draws on this established system as supporting authority for the analysis that follows. Several commentators are careful here: the Sankhya of Kapila disagrees with Vedanta on the highest matter, the supreme oneness of Brahman, yet on the narrower technical question of how the gunas function and divide their effects it is competent and reliable, so it can be cited in support without contradiction.

Krishna ends by telling Arjuna to hear these distinctions yatha-vat, 'as they truly are,' duly and in proper order. This is an instruction to listen accurately, not to filter the teaching through habitual assumptions. The purpose of the whole exercise, as the placement-minded commentators read it, connects to the wider arc of the Gita. Chapter fourteen set out how the gunas bind, and chapter seventeen set out the threefold inborn dispositions of the gunas so that one might move from rajasic and tamasic tendencies toward the sattvic. Here the threefold analysis serves a further end: to show that all activity, with its factors and fruits, belongs to the gunas, so the self in its own nature stands apart from action.

Divergence
Advaita Vedānta
These commentators read the verse as preparing the ground for liberation by detaching the self from all activity. The threefold sorting is meant to show that knowledge, action, and the doer are entirely products of the gunas, so that the true self, which is by nature beyond the gunas, has no real connection with acting, with the factors of action, or with its fruits. On this reading the restrictive 'only' (eva) denies agency to the self itself, leaving agency to belong only to the limiting adjunct of the three gunas. One of these commentators adds a sharp point on why the doer is even mentioned separately: it is to ward off the error of bad logicians who imagine the doer to be the self. Another explains why only three of the six items from the previous verse (knowledge, knowable, knower, instrument, action, agent) are sorted here: the knower and agent are really one conscious principle, while the knowable and the instrument are insentient like a pot or an axe and so are not given an independent guna-threefoldness, against a Sankhya tendency to extend the threefoldness even to them.

Viśiṣṭādvaita
These commentators keep the gloss close and functional. Knowledge is specified as the knowledge whose object is the action to be done, the action is the deed actually being carried out, and the doer is its carrier-out; all three are declared threefold by the difference of the gunas, sattva and the rest. The verse simply announces the guna-sorting of this action-triad, and Arjuna is to hear them as they truly are. There is no move here to dissolve the self's connection with action; the focus stays on accurately receiving the coming classification.
Rāmānujācārya · Vedānta Deśika
Śuddhādvaita
These commentators identify the triad precisely: jnana as the means, karma as the activity, and karta as the person, each becoming threefold as sattvic and so on. One of them draws out a distinctive purpose from the very phrase 'spoken in Sankhya, listen also to these.' On his reading, the threefold actions Krishna taught in chapter seventeen were the kind that fit a person for the nirguna (quality-transcending) state, whereas the distinctions taught here are not of that liberating kind; they are presented so that the difference of their intrinsic natures may simply be known and recognized.
Vallabhācārya · Śrī Puruṣottama
Kashmir Shaivism
This commentator reads the terms of the verse as compressed pairs, recovering all six items of the previous verse within the three named here. 'Knowledge' stands for the instrument that operates in both knowing and acting, taken as twofold; 'action' covers both the knowable and the thing-to-be-done; and 'doer' covers both the knower and the agent. So the verse, in brief, shows the difference among all six by the difference of the gunas, and the Sankhya conclusion is the doctrine in which this enumeration of the gunas is settled.
Ācārya Abhinavagupta
Bhakti
These commentators emphasize the practical, devotional weight of the sorting. One reads it as a direct caution: since knowledge, action, and the doer each come in three kinds, and two of them, the rajasic and the tamasic, are fettering while only the sattvic can lead toward salvation, Arjuna is told not to put blind faith in knowledge, action, and doership as such, but to learn to recognize and prefer the sattvic kind. He praises the Sankhya as the very science that distinguishes Purusha from Prakriti and measures the mountain of ignorance with its enumeration of elements. The placement-minded among them recall chapters fourteen and seventeen to mark that here the threefoldness is set out to show the self's standing apart from action, factor, and fruit.

Dvaita
These commentators are mainly concerned to establish the relevance of this passage to the present topic and to fix the reference of 'guna-sankhyana.' The point of restating the guna-distinctions, introduced with 'again,' is that these divisions according to the qualities serve as a means to liberation and have been touched on earlier as well. As for 'the enumeration of the qualities,' while it points to the system of Kapila, what is ultimately intended is the Vedic enumeration of the gunas, not a merely sectarian Sankhya authority.
Madhvācārya · Śrī Jayatīrtha

These commentators bring out the structural and practical value of the announcement. One notes the technical mechanics behind action: before any deed, the mind must first resolve upon it (karma-codana, the inner inspiration to act, carrying the triad of knower, knowable, and knowledge), after which the doer gathers instruments and produces the external act (karma-samgraha); the verse now defines 'jnana' from the inner triad and 'karma' and 'karta' from the outer. Another stresses that Krishna is pre-announcing nine items so the seeker will not lose his way as the verses unfold, and that the whole apparatus is a mirror in which one is to recognize one's own knowledge, action, and doership and shift each toward the sattvic. A third underlines that the Sankhya, though opposed to Vedanta on the supreme truth, is a genuine authority on the science of the gunas.

If knowledge, action, and even the doer are all just products of the gunas with no fourth option, where am 'I' in any of this, and what difference does it make whether my activity is sattvic, rajasic, or tamasic?
The verse is deliberately exhaustive: 'threefold only' rules out any fourth category, because knowledge, action, and doership are by their nature woven of the three gunas. That very completeness is the point. When you see that all of it, including the felt sense of being the doer, belongs to the play of the gunas, you begin to see that your true self is not located inside that machinery at all.
Śaṅkarācārya · Śrī Ānandagiri · Madhusūdana Sarasvatī · Śrī Nīlakaṇṭha
Several commentators say this is exactly why the verse exists. After chapter fourteen showed how the gunas bind and chapter seventeen mapped the dispositions they produce, this analysis is given to show that action, its factors, and its fruits all relate to the gunas, so the self stands apart from them. One adds that the doer is named separately precisely to correct the mistake of thinking the doer is the self; the restrictive 'only' denies agency to the self and leaves it to the limiting adjunct of the gunas.
Madhusūdana Sarasvatī · Śrīdhara Svāmī · Śaṅkarācārya
Yet the difference between sattvic, rajasic, and tamasic still matters enormously while you are on the path. Of the three, the rajasic and the tamasic fetter, and only the sattvic can lead toward release; so you are told not to put blind faith in knowledge, action, and doership as such, but to learn to recognize the kinds and prefer the sattvic. The whole nine-fold scheme is a mirror in which to recognize your own knowledge, action, and doership and to shift each, deliberately, toward the sattvic.
Sant Jñāneśvar · Swami Ramsukhdas
Contemplation
Take this verse as a mirror held up to your own life. Krishna is about to lay out nine kinds of inner experience: three sorts of knowledge, three sorts of action, three sorts of doer, one sattvic, one rajasic, one tamasic in each. The whole apparatus is not abstract philosophy. It is a mirror in which you are meant to recognize your own knowledge, your own activity, and your own sense of being the doer. As the coming verses unfold, do not lose your way in the list. Instead, keep asking honestly: of these three, which is mine right now? And then let the recognition move you, gently, toward the sattvic in each. Hear it yatha-vat, as the matter truly is, not as you are used to imagining yourself to be.
