Sadhana Pada 2.16 — The Suffering Yet to Come Is to Be Avoided

The suffering that has not yet come is what is to be prevented.

Unpacking the words: future suffering as the field of action

The sutra is austere — three words — yet each carries weight. Heya (from the root ha, “to abandon, to leave, to be discarded”) is a verbal adjective meaning “that which is to be given up, prevented, or removed.” It is the technical term that organizes this whole section of the pada: what is to be removed (heya), the cause of what is to be removed (heya-hetu), removal itself (hana), and the means of removal (hana-upaya). Duḥkha — literally “a bad axle-hole,” the wheel that turns roughly on its axle — is suffering in its widest sense: pain, dissatisfaction, the friction inherent in changing experience. Anāgata is built from the negative an- and āgata, “come, arrived” (from ā-gam, “to come”); it means “not yet come,” the future that has not yet arrived. Read together, heyaṃ duḥkham anāgatam declares that the suffering still to come is precisely what is to be prevented.

The choice of anāgata is deliberate and exact. Patanjali does not say all suffering is to be removed, as if one could unmake the past or instantly dissolve the present. He marks out the one region where action has purchase: the unwritten future. The grammar itself enacts the teaching — it points the practitioner away from grief and toward work.

What the sutra asserts

Having declared in the previous sutra that all changing experience carries suffering, Patanjali immediately narrows the field of action with a single practical line: only future suffering can be averted. The past is gone and cannot be unmade; present suffering is already arising and must be borne. But the suffering that has not yet come stands open, not yet inevitable, and it is here that the whole effort of yoga is directed.

There is a quiet wisdom in this focus. It spares the practitioner the futile grief of trying to rewrite the past and the equally futile demand that present pain simply vanish. It places the leverage exactly where leverage exists — in the unwritten future. Because the causes of suffering ripen in time, intervening now in those causes can keep tomorrow’s pain from forming at all. Yoga is therefore preventive at its root: it does not merely soothe suffering once it arrives but works to ensure that the deeper suffering of bondage never arises again.

The phrasing also carries hope. To say suffering is to be prevented is to assert that it can be — that the chain of cause and effect, once understood, can be broken before its painful fruit appears. The diagnosis of the preceding sutra might have sounded like a sentence; this sutra reveals it to be a problem with a solution, and turns the practitioner from a sufferer into someone with work to do.

The place in the pada’s argument

This sutra is the second member of a deliberate fourfold structure that the classical commentators compared to the framework of medicine: the disease, its cause, the cure, and the means of cure. Sutra 2.15 named the disease — the universal suffering that the discerning feel in all changing things. The present sutra names what is treatable within that diagnosis: the suffering still to come. Sutra 2.17 will name the cause — the conjunction of seer and seen. And the later sutras 2.25 and 2.26 will name the cure (the cessation of that conjunction) and its means (unbroken discriminative discernment). By isolating future suffering as the target, Patanjali keeps the teaching from collapsing into either despair over what cannot be changed or denial of what already is.

This medical analogy is not a later imposition but is woven into the very vocabulary of the section. The four-term skeleton — the removable, its cause, the removal, the means — mirrors the physician’s movement from symptom to diagnosis to prognosis to treatment. Placed here, the sutra is the hinge between bleak diagnosis and hopeful prescription: it is the moment the text turns from describing the human condition to acting upon it.

The commentary tradition

Vyasa, in the foundational Yoga-Bhāṣya, draws out the medical parallel explicitly, treating this sutra as the statement of what is to be cured and reading the future tense as the whole rationale for the discipline that follows: a science worth undertaking only because something can yet be prevented. He stresses that past suffering, being consumed, and present suffering, being already in the moment of experience, fall outside the scope of what practice can touch; the energy of yoga is reserved for what has not yet ripened.

Vacaspati Misra, in his sub-commentary the Tattva-vaiśāradī, sharpens the point by anticipating an objection — if suffering is the very nature of changing existence, how can any of it be avoided? — and answers that it is avoidable precisely because it is not yet present; what has not arisen can be kept from arising by removing its conditions. Vijnanabhiksu, reading the text through his more theistic and reconciliatory lens, underscores that this preventability is what dignifies the whole undertaking, distinguishing the yogic project from mere endurance: the goal is not to tolerate suffering but to end its future production altogether. Bhoja, in the Rājamārtaṇḍa, reads the line tersely as the definition of the object of avoidance, fixing the term heya as the technical pivot on which the next several sutras turn.

A note on the discipline of focus

Underlying the sutra is the Samkhya conviction that experience unfolds according to cause and effect — that the impressions and afflictions accumulated in the mind ripen, in time, into further experience and further suffering. Because this ripening lies in the future, it is workable. The practitioner does not fight the harvest already gathered; the practitioner tends the field where next season’s crop has not yet sprouted. This is why the entire architecture of yoga — the cultivation of discernment, the loosening of the afflictions, the stilling of the mind’s turnings — is fundamentally forward-facing. It is an investment of present effort against a future that has not yet hardened into fact.

There is a further subtlety in the term anāgata that the tradition does not let pass. The future suffering Patanjali means is not chiefly the ordinary pains of the coming years — illnesses, losses, disappointments — for many of these are the ripening of seeds already sown and cannot all be averted. What is most fully preventable is the deeper suffering of continued bondage: the perpetuation of the conjunction that keeps the witness mistaking itself for the changing field, life after life. The future the sutra opens onto is therefore not merely tomorrow but the whole onward momentum of unliberated experience, and it is this momentum, above all, that the discipline is built to arrest.

Why prevention, not mere endurance

It is worth marking how this sutra distinguishes the yogic stance from simple stoic endurance or resignation. To endure suffering nobly is admirable, but it leaves the machinery that produces suffering intact. Patanjali asks for something more demanding and more hopeful: to act on the causes so that the suffering need not be produced in the first place. Endurance meets pain at the door; prevention dismantles the road by which it comes. The whole weight of the sādhana pāda — the practices, the restraints and observances, the limbs of yoga taken up from sutra 2.28 onward — rests on this single conviction that future suffering is not fated but conditioned, and that what is conditioned can be unconditioned.

This is also why the line is placed before the cause is named rather than after. Patanjali first establishes that there is something to be done — that a portion of suffering is genuinely open to action — and only then, in the next sutra, identifies what that action must address. The order is pedagogical: hope before diagnosis, the assurance that the disease is curable before the unflinching account of its root. A practitioner who did not first believe suffering preventable would have no reason to undertake the long and exacting work that the rest of the pada describes.

The Buddhist path

The orientation toward preventing future suffering is the practical hinge of the Buddha’s path as well. The third and fourth noble truths — that suffering can cease, and that there is a way leading to its cessation — rest on exactly this confidence: that by acting now on the causes, the suffering that would otherwise arise need not arise. Both traditions reject fatalism in favor of a clear-eyed, forward-looking discipline, and both locate the leverage in the conditions of suffering rather than in the suffering itself.

The Stoic division

The Stoics drew the same line between what we can and cannot affect. The Enchiridion opens by dividing all things into those within our power and those not, counseling us to spend our effort only where it can reach. The past and the unalterable belong to nature; our own future responses, judgments, and disturbances are ours to shape. To work on the suffering still to come, and to release what is already fixed, is the heart of Stoic practice as much as of yoga.

Acting upstream

The contemplative and wisdom traditions broadly favor this preventive posture over remedial complaint. The Tao Te Ching advises dealing with the difficult while it is still easy and the great while it is still small — to deal with a thing before it comes into existence — a counsel almost identical in spirit to averting suffering before it forms. The shared intuition across these schools is that wisdom acts upstream, at the causes, rather than downstream, at the symptoms.

Everyone instinctively understands that some pain is unavoidable and some is preventable, and that wisdom lies in telling the two apart. We cannot un-break what is broken, and we cannot will away the grief that is on us now — but we can, often, keep tomorrow’s troubles from taking root by what we attend to today. This sutra crystallizes that ordinary good sense into a principle: aim your effort where it can still make a difference.

The teaching is freeing because it relieves us of two heavy and useless burdens — regret over the unchangeable past and the demand that present pain instantly disappear. With those set down, our energy returns to the one place it can actually work. Whether the suffering in question is a health crisis, a strained relationship, or the deeper restlessness of a life built on the impermanent, the counsel is the same: stop fighting what is fixed, and tend the causes of what is still to come.

1. A charter for prevention

This sutra reads almost as a charter for the modern idea of prevention. Preventive care, financial planning, conflict de-escalation, building resilience before a crisis — all rest on the same logic, that acting on causes now spares us larger suffering later. Patanjali’s spiritual psychology shares its grammar with these practical disciplines, treating the inner life as something that can be cared for upstream rather than only patched up after it breaks.

2. A corrective to rumination

It also speaks to a common modern affliction: the mind’s habit of circling endlessly over a past it cannot change. The useful, forward-looking work of problem-solving is one thing; the corrosive replaying of what is already done is another, and this sutra draws exactly that line.

3. Grieve, release, then act

The counsel is to grieve what must be grieved, release what cannot be altered, and pour genuine effort into shaping the suffering that has not yet arrived. In a culture prone both to anxious dwelling on the past and to naive denial of consequences, that balance is quietly radical — it neither suppresses present pain nor squanders energy on the unchangeable.
