Nature does the producing; you do the experiencing, and the two are not the same thing.
It is tempting to think the self is doing everything, including the body's acting and the senses' reaching. This verse draws the line more carefully: the doing belongs to nature, and only the felt undergoing of pleasure and pain belongs to you.
Nature is said to be the cause when it comes to producing the body and its instruments. The conscious self is said to be the cause when it comes to experiencing pleasure and pain.
The reading read whole, as one unhurried piece
Where it stands
Krishna has just named both nature and the self as beginningless. Now he divides the work between them: one side of bound life belongs to nature's producing, the other to the self's experiencing, and the whole round of birth and death depends on both operating at once.
The teaching
Two distinct roles are named here, and it matters that they are not confused with each other. The effect is the body; the instruments are the senses and organs that operate within it, along with the very qualities of pleasure, pain, and delusion that rest in those instruments. Producing all of this, running it, being the agent of the body and its machinery, belongs to nature. You did not build your body, and in the strict sense drawn here, you are not the one running its instruments either. That work is nature's own. What is left to you is something narrower and, in its way, more intimate. You are the cause in the matter of experiencing pleasure and pain. Nature can produce the occasion, the contact, the circumstance, but the actual feeling of it, the undergoing, is credited to the conscious self alone. This is why neither nature nor the self, taken by itself, can produce a wanderer caught in the round of birth and death. Unconscious nature, however elaborate its productions, cannot feel anything on its own. The self, changeless in itself, does not act and does not undergo anything until it is joined to what nature has produced. The round arises only where the two meet. How does something without awareness come to act at all? The commentators reach for the same kind of image: fire makes iron glow, though the iron has no fire in it; a cow's milk flows at the mere nearness of her calf. Nature's agency, in the same way, is lent to it by the bare proximity of the conscious self. And the felt experiencing, the actual pleasure and actual pain, belongs only to what is conscious, and is laid, by that same proximity, onto you. What keeps this joining going, rather than settling once and dissolving, is attachment to the very qualities nature produces. Clinging to the pleasures and pains that arise casts the self into one womb after another, high and low, and from that birth comes action, and from that action another birth, turning as long as the self keeps serving the qualities rather than the deeper thing they were always meant to point toward.
The doubt that rises
If nature does the producing and I only do the experiencing, am I doing anything at all, or only suffering and enjoying what happens to me? And if the joining of the two is what keeps the round turning, is that joining something I can actually loosen, or only something I can understand?
Where the paths divide
Read as an explanation of bondage, not the self's final truth.
For you, the division holds well enough to explain how the round of birth and death comes about: nature genuinely produces the body and its instruments, and you genuinely appear to experience their fruit. But the joining underneath this division is itself of the nature of ignorance. It is not what you finally are. The round of birth and death is precisely your full undergoing of pleasure and pain within that ignorant joining, not a permanent feature carved into your nature.
Read as an ordered division within the Lord's own being.
For you, nature and self are not two independent powers squared off against each other. Both are the Lord's own nature, His lower and His higher, and this verse shows the proper roles within that single ownership: nature as agent of effect and instrument, you as the one who enjoys pleasure and pain, neither straying into the other's work. What keeps this arrangement running, and keeps you cycling through wombs, is your own attachment to the qualities nature produces.
Read as a correction: nature's agency is only a figure of speech.
For you, nature's so-called agency should not be taken literally. It is called the cause of effect and instrument only because it is the material that transforms, never because it truly acts the way a conscious being acts. Genuine doership, exactly like genuine enjoyership, belongs solely to you, the conscious person, since nature has no awareness whatsoever and can only ever undergo change, never bring anything about on its own.
Extant comment here is only a cross-reference; what follows is flagged as extension, not his recorded word.
Abhinavagupta's surviving remark at this exact line does not develop it on its own terms; it points back to his comment at 13.20, which treats this whole stretch as one passage and describes nature and the person as leaning on each other like the lame man and the blind man, each supplying what the other lacks. Extended cautiously from that image, though not his own recorded word at 13.21, the division named here might be read as one more form of that mutual leaning: consciousness lending nature the appearance of doing, nature in turn giving consciousness something through which to recognize itself.
Read through the mechanism by which an unconscious nature comes to act at all.
For you, the puzzle of how something unconscious can act is answered by nearness alone. Nature is lent its agency the way fire lends iron its glow, or the way a cow's milk flows at her calf's mere presence. It does not act on its own steam. And the felt experiencing of pleasure and pain, in turn, belongs only to what is conscious, which is to say, to you, laid onto you by that same bare nearness rather than manufactured by nature itself.
Read as a clean division of causal labor, kept sharp and distinct.
For you, this verse is best held as a working definition: nature is the cause in the sense of agency over effect and instrument; you are the cause in the sense of enjoyership over happiness and sorrow, itself an active grasping colored by a movement of mind, not a bare passive registering. The round of birth and death depends on both roles operating together, and neither can substitute for the other.
All six readings agree that the doing belongs to nature and the felt experiencing belongs to you, and that neither piece alone produces the round of birth and death. They part on what the division ultimately means. Is it a temporary feature of an ignorant joining that dissolves with knowledge, an ordered role inside the Lord's own being, a strict metaphysical fact about two irreducibly different kinds of reality, or a working definition useful chiefly for practice? The verse itself does not adjudicate, and this page will not settle it for you.
A question to carry
Right now, in this moment, can you tell which portfolio is actually running, nature's producing or your own experiencing, and what changes if you stop treating the second as if it were the first?
Where this teaching travels
Verses that sit near this one, each going its own way; follow whichever calls you.
So let the body act and the senses reach where nature takes them. Watch instead for the felt edge that is genuinely yours to hold, and hold it a little more lightly than you have been holding it until now.

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 body's producing and the senses' working belong to nature; only the felt pleasure and pain belong to you.

The verse splits the labor of bound life cleanly in two. Nature is the cause when it comes to producing the effect and the instrument, the body and its senses; the conscious self is the cause when it comes to experiencing the pleasure and pain that result. The doing belongs to one side, the feeling to the other, and no commentator collapses this basic division.
Neither piece alone makes a wanderer: unconscious nature cannot feel, and the changeless self cannot act or undergo anything by itself.

Neither portfolio produces a wanderer caught in birth and death on its own. Insentient nature, however busy, cannot feel anything; the conscious self, however aware, changes nothing on its own and undergoes nothing until it is joined to nature's productions. The round of birth and death arises only where the two are joined together.
Nature's agency is lent to it by the mere nearness of consciousness, the way fire makes iron glow.

There is a real puzzle underneath the division: how can something unconscious act, and how can something changeless feel?

Nature's agency is lent to it by the bare proximity of consciousness; nature does not act on its own steam.
Enjoyership, the felt experiencing of pleasure and pain, belongs strictly to what is conscious, never to the mechanism producing the occasion.

The felt experiencing of pleasure and pain, whatever its ultimate status, belongs strictly to what is conscious. Nature can produce the conditions for pleasure and pain, but the undergoing of them, the actual feeling, is credited to the self alone, never to the mechanism that produced the occasion for it.
What keeps the round turning is attachment to the qualities nature produces, and loosening that attachment is exactly where practice has its place.

What keeps the self tied to this arrangement, on the readings that trace the verse's continuation, is its own attachment to the qualities nature produces. That clinging is what casts the self into one womb after another, and the round keeps turning for exactly as long as the self keeps serving the qualities rather than the means of reaching itself.
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 folds the whole division into the Lord's own twofold nature: prakriti as His lower nature, the self as an aspect of His higher nature. Nature acts, the self enjoys, and neither strays into the other's role, but this is not a standoff between two independent principles; it is an ordered division of labor within one divine ownership, and what perpetuates it is the self's attachment to the qualities.
Dvaita, in their fuller words
Madhva insists that nature's agency is only a figure of speech: prakriti is called the cause of effect and instrument merely because it is the material that transforms, never because it truly acts as an agent. Genuine doership, exactly like genuine enjoyership, belongs only to the conscious person, since prakriti has no awareness whatsoever and can only undergo change.
Bhakti, in their fuller words
Sridhara stresses the mechanism by which an unconscious nature comes to act at all: agency is lent to it by the bare nearness of the conscious self, the way fire makes iron glow. Enjoyership, the feeling of pleasure and pain, belongs only to the conscious and is likewise laid onto the self only by that same nearness. Neither side, alone, could produce the wandering that binds a soul.
A modern reading, in their fuller words
Madhusudana treats the verse as a clean, almost technical division of causal labor: nature is the cause in the agency of effect and instrument, the person the cause in the enjoyership of happiness and sorrow, this enjoyership itself being a grasping colored by a movement of the mind. The round of birth and death depends on both roles operating together, with neither substituting for the other.
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
Notice, right now, which of the two portfolios is actually running. The body is doing something, the senses are reaching toward something, and if you look closely, even the sense of being the one who acts is only a movement passing through you. What is harder to see, and worth sitting with, is the felt edge itself, the pleasure or discomfort you are registering this very moment, and whether it is truly yours to hold onto, or only yours to notice.
So let the body act and the senses reach where they will; watch instead for the felt edge that is genuinely yours, and hold it a little more lightly than you have been holding it.

Advaita Vedānta
Shankara reads the division as real enough to explain bondage but not as the final truth of the self. Nature genuinely produces the body and instruments, and the self genuinely appears to enjoy their fruits, but this joining is of the nature of ignorance. The round of birth and death is precisely the self's full undergoing of pleasure and pain that this ignorant joining makes possible, not a permanent feature of what the self actually is.

Madhusūdana Sarasvatī
A Seeker Asks
If nature does all the producing and I only experience the result, am I responsible for anything at all, and how would I ever act differently?
The verse is not describing helplessness. It is describing where two different kinds of causality operate: nature causes the body and its instruments to arise and function, and you are the cause of nothing there. But the experiencing itself, the actual undergoing of pleasure and pain, is credited to you, and that undergoing is exactly where responsibility and practice have their place.
Śaṅkarācārya · Śrīdhara Svāmī
What keeps the round turning, on the readings that trace the verse forward, is not nature's productions themselves but your attachment to them. Nature will keep producing pleasure and pain regardless. What is yours to change is the clinging that turns those productions into a chain of new action and new birth.
Rāmānujācārya · Madhusūdana Sarasvatī
So the answer is not fatalism but a redirection of effort. You cannot stop nature from producing effects, and you should not expect to. What you can loosen is the felt sense that you are the one inside it all, gathering pleasure and pain as your personal possession rather than letting them pass through as nature's own weather.

What is harder to see, and worth sitting with, is the felt edge itself, the pleasure or discomfort you are registering this very moment, and whether it is truly yours to hold onto, or only yours to notice.
