Health, Wellness and Psychology

आयुर्वेदः · योगः

A definition of health from perhaps the second century BCE that includes mental wellbeing — something the World Health Organization added to its own definition only in 1948. A causal analysis of disease that fits on a three-by-three grid. And an eight-stage discipline for the mind that is now the subject of controlled trials.

This chapter sets out the system as it understands itself, and is explicit about where the claims are established and where they are not.

1Health as an individual matterप्रकृतिभेदः

The single most consequential difference between Āyurveda and modern clinical medicine is not a claim about the body. It is a claim about who the norm applies to.

Population norms compared with individual constitution Modern medicine defines health against population averages; Ayurveda defines it against an individual's own constitution. A population norm the average A reference range is defined across everyone, and an individual is assessed against it. An individual norm — prakṛti Each person has their own constitution, and health is balance relative to that — so the first clinical task is to establish what this person's normal is.
Neither approach is complete on its own. Population norms make epidemiology and clinical trials possible; individual constitution makes sense of why the same regimen suits one person and harms another. Modern medicine has been moving toward the second under the name “personalised medicine”, which is worth noting without overstating the parallel — pharmacogenomics and doṣa theory are not the same idea.

The framing sits inside the four puruṣārthas of chapter 4. The body is not the point; it is the instrument by which a person pursues dharma, artha, kāma and mokṣa. Health matters because an unhealthy instrument cannot do the work. That premise produces a system weighted toward prevention and maintenance rather than intervention — most of Āyurveda's content is about what to do when you are well.

2The definitionस्वस्थलक्षणम्

समदोषः समाग्निश्च समधातुमलक्रियः ।
प्रसन्नात्मेन्द्रियमनाः स्वस्थ इत्यभिधीयते ॥

sama-doṣaḥ samāgniś ca sama-dhātu-mala-kriyaḥ |
prasanna-ātmendriya-manāḥ svastha ity abhidhīyate ||

Suśruta-saṃhitā, Sūtrasthāna 15.48

The two halves of the classical definition of health The first line covers physical balance of dosas, digestive fire and tissues; the second covers a pleasant state of self, senses and mind. FIRST LINE — THE PHYSICAL “whose doṣas are in balance, whose agni is in balance, whose tissues and wastes function in balance…” Doṣas · §4 Agni · §7 Dhātus and malas · §6 the three regulating principles the digestive and metabolic fire the seven tissues, and the elimination of wastes SECOND LINE — THE PSYCHOLOGICAL “…and whose self, senses and mind are content — that person is called svastha, established in themselves.” Ātman Indriyas Manas · §8 the self the senses the mind
The word for “healthy” is स्वस्थ, svastha — literally “standing in oneself”. Health is not the absence of disease but a state of being properly established, and the definition requires both halves. The WHO's 1948 constitution defines health as “a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity”; the parallel to the second line is close, and was noticed at the time.

3Borrowed foundationsदर्शनाश्रयः

Āyurveda does not invent its metaphysics. It takes it, explicitly, from two of the darśanas of chapter 3.

From Sāṅkhya

The analysis of a person into twenty-four elements — the evolutes of prakṛti from intellect down through the sense capacities to the gross elements. This is the framework Āyurveda uses to describe the anatomy and psychology of a human being as a single continuous structure rather than as a body with a mind attached.

From Vaiśeṣika

The six categories, and in particular the nine substances of chapter 7. The clinically operative move: when substances become joined to the indriyas, the senses, they become cetana-dravya — sentient substance. A practitioner is treating a substance that feels, and the texts insist this must never be forgotten at the bedside.

4The three doṣasत्रिदोषम्

The word दोष (doṣa) means that which can spoil or go wrong. The three are not humours in the Greek sense and not substances that can be isolated; they are named functional principles, each composed of two of the five elements.

The three dosas and their elemental composition Vata from air and space, Pitta from fire and water, Kapha from water and earth, with the function each governs. Vāta वात Vāyu · air Ākāśa · space The principle of motion All movement in the body: breath, circulation, nerve impulse, elimination, the movement of thought. SEATED BELOW THE NAVEL dominant in old age dominant in the evening, and in the last watch of the night chief organ: the digestive system Pitta पित्त Agni · fire Āpas · water The principle of transformation All chemical activity: digestion, metabolism, body heat, vision, and the “digestion” of experience into understanding. SEATED BETWEEN CHEST AND NAVEL dominant in youth and middle life dominant at midday, and at the middle of the night chief organs: liver and pancreas Kapha कफ Āpas · water Pṛthivī · earth The principle of structure The solid substratum: tissue, lubrication, cohesion, immunity, stability — and patience and steadiness of temperament. SEATED FROM HEAD TO CHEST dominant in childhood dominant in the morning, and in the first watch of the night chief organ: the chest
The three coexist in a proportion particular to each person, and function complementarily despite having opposite properties. Health is that proportion holding; disease is its disturbance. Note that each doṣa has a time of day, a season of life and a bodily region — so the same complaint is read differently in a child in the morning and an old person in the evening.

5Balance and imbalanceवृद्धिक्षयौ

What each doṣa does when balanced, in excess, and depleted
VātaPittaKapha
BalancedEnergy; even breath; free movement; regular urgesDigestion, warmth, vision, hunger, thirst, taste; clarity, intelligence, courage, softnessStability, moisture, sound joints, patience
In excessThinness; craving warmth; shivering; constipation; weakness; chattering; dizzinessYellowness in the eyes and excretions; severe hunger and thirst; burning; insomnia; acidityIndigestion; nausea; lassitude; heaviness; feeling cold; slack limbs
DepletedExhaustion of the limbs; disordered speech; giddinessIndigestion; coldness; loss of lustreGiddiness; a feeling of emptiness in the seat of kapha; loose joints
Why both directions matter

Each doṣa can be too much or too little, and the two produce different pictures. This gives the system six failure modes rather than three, and it is why a treatment aimed at reducing something can itself cause disease if carried too far. The tradition's word for the correct target is sama — level, even — not minimum.

6The seven tissuesसप्त धातवः

The body is built of seven dhātus, and the striking claim is that they form a sequence: each is produced from the one before it, in order, over time.

The chain of seven tissues from food to ojas Food becomes plasma, then blood, flesh, fat, bone, marrow, reproductive tissue, and finally ojas. āhārafood Rasaplasma Raktablood Māṃsaflesh Medasfat Asthibone Majjāmarrow Śukrareproductive Ojasthe vital essence Each tissue is the raw material for the next, so a deficiency anywhere propagates downstream — a fault in digestion shows up eventually in bone. Ojas is the refined end-product, held to underwrite immunity, vigour and long life. Its depletion is the general form of debility. The chain has real clinical consequences: it tells the practitioner to look upstream of the presenting complaint.
Signs of excess and deficiency in each tissue
DhātuExcessDeficiency
RasaSymptoms resembling excess kaphaRoughness, weakness, dryness, fatigue, intolerance of sound
RaktaSpreading skin eruptions; enlargement of the spleen; fissures; skin disease; gumboilSlackness of the blood vessels; roughness
MāṃsaBoils, tumours, hardening of vessels, goitre, mumpsSensory fatigue; dryness of the cheeks; joint pain
MedasWeakness and breathlessnessLoss of the sense of touch; thinness
AsthiExcess growth of bone and teethPain in bones; loss of teeth
MajjāHeaviness in the eyes and body; joint painPorosity of bone; giddiness; blackouts
ŚukraExcessive desire; calculiPain in the reproductive organs; premature emission

7Agniअग्निः

Of the three components in the first line of the definition, agni is the one with no European counterpart and the one the tradition treats as most important.

The role of agni and what happens when it is disturbed Agni converts food into tissue; if there is no food it consumes the dosas, then the tissues, then the vital energies. What agni is Not a flame. It exists in the body in liquid form and manifests through Pitta. Its function is conversion: it cooks what is eaten and turns it into what the body is made of. Disturbed agni — too low, too high, or erratic — makes the person ill regardless of what they eat. When agni is extinguished, the person dies. When it is in its normal state, they live long and well. The consequence of not eating If there is no food, the fire does not go out. It burns what is there: first the doṣas then the dhātus — the tissues themselves then the vital energies Which is why keeping agni in balance — not merely fed — is treated as the central discipline of daily life.
Read charitably, agni names the whole of what would now be distributed across digestive enzymes, gut absorption, hepatic metabolism and basal metabolic rate. Read as a clinical heuristic, “assess the digestive capacity before prescribing anything” is sound advice that modern practice arrives at from a different direction.

8Manas and the guṇasमनः · त्रिगुणाः

मनस् (manas), the mind, is treated as a subtle internal organ: it cannot be seen, but its presence is inferred from its effects. It is the internal sense by which one is aware of pleasure and pain, and — in a formulation that connects this chapter to chapter 3 — it is the cause both of bondage and of release. Left ungoverned, the sense organs act without restraint.

For the analysis of temperament and behaviour, Āyurveda takes the Sāṅkhya doctrine of the three guṇas.

The three gunas as a psychological framework Sattva, rajas and tamas, with the states each produces; rajas and tamas when disturbed cause psychological disorder. Sattva सत्त्व Clarity, lightness, equanimity. The state in which perception is accurate and judgment is sound. THE TARGET STATE Rajas रजस् Activity, restlessness, craving. Necessary for action — and the source of agitation when unchecked. A DOṢA OF THE MIND Tamas तमस् Inertia, heaviness, obscuration. Necessary for rest and sleep — and the source of dullness in excess. A DOṢA OF THE MIND The framework is used clinically: every action and behaviour can be classified by which guṇa predominates, which gives the practitioner a way to describe a person psychologically. When rajas and tamas are disturbed, they cause psychological disorder — so they are the mental counterparts of the doṣas, and are named as such in the texts.

9Caraka's causal gridत्रिविधो हेतुसङ्ग्रहः

The most elegant single passage in the corpus: a complete aetiology of disease, physical and mental together, in one line.

कालबुद्धीन्द्रियार्थानां योगो मिथ्या न चाति च ।
द्व्याश्रयाणां व्याधीनां त्रिविधो हेतुसङ्ग्रहः ॥

kāla-buddhīndriyārthānāṃ yogo mithyā na cāti ca |
dvyāśrayāṇāṃ vyādhīnāṃ trividho hetu-saṅgrahaḥ ||

Caraka-saṃhitā, Sūtrasthāna 1.54

Three factors by three modes of misuse gives nine causes of disease Time, intellect and sense-objects, each engaged wrongly, insufficiently or excessively. MITHYĀ-YOGAwrong engagement A-YOGAnon-engagement ATI-YOGAexcessive engagement Kālaकाल time · season Doing summer things inwinter; sleeping by day andwaking at night. Ignoring the seasonaltogether; no seasonaladjustment at all. Excessive exposure — toomuch cold, heat or damp fortoo long. Buddhiबुद्धि judgment Acting against what oneknows to be right —prajñāparādha. Failing to use judgmentat all; acting withoutthought. Overthinking; excessivemental exertion beyondcapacity. Indriyārthaइन्द्रियार्थ sense-objects Improper contact — readingin bad light, unwholesomefood, harsh sounds. Sensory deprivation —withholding the sensesfrom their objects. Overstimulation — too muchnoise, light, food, orsensory input. “Of diseases resting on both [body and mind], the summary of causes is threefold” — three factors, each capable of three kinds of misuse: nine causes, covering everything.
The phrase dvyāśrayāṇām — “resting on both” — is the load-bearing word. Caraka does not treat somatic and psychic disease as separate domains requiring separate causes. The same grid explains both, which is a considerably stronger commitment to psychosomatic unity than Western medicine held until well into the twentieth century.
Prajñāparādha

The middle-left cell has a name of its own: प्रज्ञापराध, “the offence against wisdom” — doing what you know perfectly well you should not. Caraka treats it as a major cause of disease, arising when buddhi (comprehension), dhṛti (self-restraint) and smṛti (recollection) are all impaired at once. It is an unusually clear-eyed piece of medicine: most of what damages people is not ignorance.

10The daily regimenदिनचर्या

Because the system is oriented to prevention, its largest body of practical instruction concerns the ordinary day. Dinacaryā covers waking to sleeping.

The daily regimen from waking to sleeping Rising before dawn, self-assessment, drinking water, elimination, oral hygiene, eye care, oil massage, exercise, bathing, and the further practices. Brāhma-muhūrtatwo muhūrtas — 96 minutes — before sunrise Rise. The hour before dawn is prescribed for waking, and is the quietest and coolest of the day. Assess the body Observe the body and the breath before doing anything. This is the basis for planning the day. Uṣaḥpānadrinking water at dawn Eight handfuls of water before sunrise, seated, before even brushing the teeth. Elimination, then oral care Evacuation of the bowels; teeth cleaned with specified tree stems; the tongue scraped with mango or guava leaf. Eyes, ears, and the body Collyrium (sauvīrāñjana) to the eyes; medicated oil in the ears (karṇapūraṇa); oil applied to the body daily. Exercise, massage, bath Physical exercise; udvartana — rubbing with fine astringent herbal powders; then bathing. Through the day Medicated smoking (dhūmapāna) · an aromatic garland · footwear · an umbrella · betel after meals · and the avoidance of wrong acts.
Two observations. First, several items are frankly climatic — footwear and an umbrella are listed as health measures, which in a hot country they are. Second, the whole regimen is organised around the doṣa clock of §4: rising in the vāta hours before dawn, exercising in the kapha hours of the morning, eating the main meal at the pitta peak of midday.

11Suppressed urgesवेगधारणम्

A distinctive and unusually specific doctrine: a major class of illness is caused by holding in natural urges. Thirteen are enumerated, each with its consequences.

UrgeDevanāgarīConsequences of suppressing it
Vāta — flatusवातRetention of faeces and urine; abdominal distension; pain; piles and other abdominal disease
Purīṣa — faecesपुरीषColic; headache; retention; cramp in the calf muscles; distension
Mūtra — urineमूत्रPain in the bladder and genitals; painful urination; headache; bending of the body
Kṣava — sneezingक्षवSpasm of the neck muscles; headache; facial paralysis; hemicrania; weakness of the organs
Tṛṣ — thirstतृष्Dryness of throat and mouth; deafness; exhaustion; weakness; cardiac pain
Kṣudh — hungerक्षुध्Abnormal thinness; weakness; change of complexion; discomfort; loss of appetite; giddiness
Nidrā — sleepनिद्राYawning, malaise, drowsiness, headache, heaviness in the eyes
Kāsa — coughकासWorsening cough; disorders of breath, taste and the heart; hiccup
Śramaśvāsa — panting after exertionश्रमश्वासChronic enlargement of the spleen; cardiac problems; fainting
Jṛmbhā — yawningजृम्भाBending of the body; muscular contraction; numbness; tremor
Aśru — tearsअश्रुInflammation of the nose; eye disease; heart disease; inability to eat; giddiness
Vamana — vomitingवमनItching; allergic reaction; loss of appetite; facial pigmentation; oedema; anaemia; fever
Retas — semenरेतस्Pain in the genitals; general weakness; cardiac pain; urinary retention
Why the doctrine is interesting even where the physiology is not

The observation underneath it is sound and not trivial: bodily processes are regulated, the signals that regulate them are informative, and routinely overriding them has costs. Modern medicine agrees for the clearest cases — habitually deferring defecation causes constipation, and chronic sleep suppression is now among the best-established risk factors in the field. The specific chains from “holding in tears” to “eye disease” are of their period; the general principle that the body's requests should be answered is not.

12Sleepनिद्रा

Caraka names three supports on which the body's strength, complexion and growth rest: food, sleep, and the regulation of the senses. Sleep is given a chapter, not a paragraph.

Sleep is the cause of joy and sorrow, of fatness and thinness, of strength and weakness, of potency and its loss, of knowledge and of ignorance.
Six kinds of sleep Sleep from tamas, from kapha, from exhaustion, from an external agent, from disease, and the natural sleep of night. Tamo-bhavā From tamas covering the mind — thereason one feels sleepy after a heavy meal. Śleṣma-samudbhavā From the influence of kapha — whychildren sleep more than adults. Manaḥ-śarīra-śrama-jā From exhaustion of mind and body —the sleep that follows real effort. Āgantukī From an external agent — a scent, amedicine, a massage, an applied oil. Vyādhy-anuvartinī From a specific disease — as in feverscaused by kapha. Rātri-svabhāva-prabhavā The sleep natural to night.The best of all six. Insomnia Leads to body pain, heaviness in the head, yawning, laziness, exhaustion, giddiness, indigestion, and vāta disorders. Excessive sleep Caused by disturbed kapha and pitta. Addressed by evacuation, medicated smoking, physical activity, fasting, and reducing tamas.
A six-way classification of sleep by cause, ranking one of them as best — that is, a diagnostic taxonomy, since the treatment for sleepiness depends entirely on which kind it is. Sleep after a heavy meal and sleep from illness call for different responses.

13Foodआहारः

Most disease, the texts hold, comes from wrong or excessive eating. The primary classification is by digestibility.

Guru — heavy गुरु

Hard to digest. Increases the quantity of bodily waste. Strengthening, satiating and growth-promoting; also causes fatigue.

Laghu — light लघु

Easy to digest. The opposite on every count: reduces weight, and assists the healing of wounds.

Neither is simply better. The judgment is a match between the food's weight and the eater's agni — which is why the assessment in §7 comes before the prescription. There is also a freshness rule: food should not have been cooked more than about three hours before eating, on the grounds that it then digests poorly and increases tamas.

14Four pillars of treatmentचिकित्सा-चतुष्पादः

Caraka's account of what a successful treatment requires names four parties, each with stated qualities. It is a systems view of clinical practice, and the patient is one of the four.

The four components of successful treatment Physician, drug, attendant and patient, each with required qualities, around the management of disease. Disease management catuṣpāda Bhiṣak — the physician Proper training · knowledge · experience The texts add: skill, and the intention to relieve suffering. Dravya — the drug Abundantly available · effective relatively safe · suitable to the form required Availability is a stated criterion — a remedy no one can obtain is no remedy. Upasthātā — the attendant Cleanliness · knowledge of patient care Affection for the patient, and skill in nursing. Rogī — the patient Provides full information · complies with instruction has the means, and the resolve The patient has duties, and treatment can fail because they are not met.
The inclusion of the attendant as a full quarter of the system, with named qualities, is notable — nursing is not treated as a subordinate activity. So is the requirement that the patient disclose fully and comply: a framework in which non-adherence is a named cause of failure rather than an inconvenience.

15Diagnosisपरीक्षा

Two examinations run in parallel: one of the disease, and one of the person who has it. The second is the longer.

The tenfold examination of the patient and the sixfold examination of the disease Ten aspects of the patient assessed, and six methods for assessing the disease. EXAMINATION OF THE PATIENT — TENFOLD Prakṛticonstitution — the person's own baseline Vikṛtimorbidity — the departure from it Sāraquality of the tissue elements Saṃhananabuild and compactness of the body Pramāṇameasurements of the body Sātmyawhat the person is habituated to and tolerates Sattvapsychological condition and resilience Āhāra-śakticapacity for food — intake and digestion Vyāyāma-śakticapacity for exertion Vayasage Six of the ten are about capacity and tolerance, not pathology. EXAMINATION OF THE DISEASE — SIXFOLD Darśana-parīkṣāinspection Sparśana-parīkṣāpalpation Praśna-parīkṣāquestioning — the history Nāḍī-parīkṣāthe pulse Mūtra-parīkṣāthe urine Mala-parīkṣāthe stool Inspection, palpation, history, pulse, urine and stool — the same six a physician without instruments has today.
The proportion is the point. Ten questions about the patient, six about the disease. A framework in which health is individual (§1) requires that most of the diagnostic effort go into establishing who this person is before asking what is wrong with them.

16Drugsऔषधम्

Rasāyana रसायन

Compound preparations of multiple herbs and minerals, closest in function to modern dietary supplements. The stated mechanisms are worth listing because they are specific: improving the nutritional value of food; improving digestion and absorption; improving transport of nutrients to the tissues; improving their availability and metabolism; strengthening immunity; and clearing the srotas, the microcirculatory channels.

Bhasma भस्म

Metal and mineral preparations reduced to a fine calcined powder by the process of chapter 10 — repeated grinding with herbal extracts and firing, sometimes for dozens or hundreds of cycles. The chemistry is real: the repeated treatment changes the particle size and the compound present.

Where the honest line falls

Two things must be said plainly. First, the pharmacopoeia is a genuine body of empirical knowledge, and several of its plants have yielded compounds of established activity — the tradition was a productive source of leads and remains one. Second, bhasmas prepared from mercury, lead and arsenic carry real toxicity risk, published analyses have found heavy metals at hazardous levels in some marketed products, and the traditional preparation's claim to render them safe is not something texts can settle. The correct response to both facts is the same: test. Efficacy and safety are empirical questions, and a tradition confident in its remedies has nothing to fear from measuring them.

17Pañcakarma and marmaपञ्चकर्म · मर्म

Treatment of an established illness typically begins with cleansing, on the premise that the accumulated products of metabolism must be removed before anything else can work.

The three phases of pancakarma Preparation with oils and sweating, then the five purification procedures, then recuperation. STEP 1 · PŪRVA-KARMA Preparation · oils and fats applied to the body · sweating (svedana) · herbs to improve digestion and metabolism The purpose is to loosen and mobilise what is to be removed. STEP 2 · PRADHĀNA-KARMA Purification — the five · emesis (vamana) · purgation (virecana) · two kinds of enema (basti) · nasal administration (nasya) Bloodletting (rakta-mokṣaṇa) is counted among them in some enumerations. STEP 3 · PAŚCĀT-KARMA Recuperation · a graduated diet, rebuilding digestive capacity slowly · prescribed changes of lifestyle The third step is the one most often skipped in commercial settings, and the texts treat it as essential. These are strong interventions. A subset is prescribed according to the patient's condition, never the whole set indiscriminately — and the ten-point assessment of §15 is what decides which.

Marma

Distribution of the marma points over the body Twenty-two points on each set of extremities, twelve on the abdomen, fourteen on the back and thirty-seven on the head and neck, totalling one hundred and seven. 37 — head and neck 22 — upper extremities 12 — abdominal region 14 — the back 22 — lower extremities 107 marma points in all What a marma is A point where muscle, cartilage, nerve, vessel and bone meet. The texts hold that vital energies concentrate there. Their first documented use is surgical, not therapeutic: Suśruta lists them as places a surgeon must avoid, graded by whether injury there is fatal, disabling or painful. In treatment, they are massaged with medicated oils, the oil and stroke chosen for the doṣa, constitution and injury.
The count of 107 is exact and consistent across the texts. The surgical origin is worth emphasising: a list of anatomical sites where injury is dangerous is precisely what an experienced battlefield surgeon would compile, and it is the kind of knowledge that gets written down because getting it wrong kills the patient.

18The eight limbsअष्टाङ्गयोगः

Patañjali's Yoga-sūtra presents a graded discipline for progressively stilling the fluctuations of the mind. Chapter 3 treats it as philosophy; here it is treated as a health regimen, which is how it is largely used today.

The eight limbs of yoga as a graded sequence From ethical restraints and observances through posture, breath and sense-withdrawal to concentration, meditation and absorption. OUTWARD — behaviour and body INWARD — attention and awareness 1 · Yamaयम Restraints. Abstention fromviolence, falsehood, dishonesty,sexual excess and acquisitiveness. Control of mind, body and speech. 2 · Niyamaनियम Observances. Purity, contentment,austerity, self-study, forbearance. Sustained practice of 1 and 2 clearsanger, envy, greed and ego — arriving at citta-śuddhi, purity of mind. 3 · Āsanaआसन Posture. Physical fitness, comfortand steadiness. The limb that in modern usage hascome to stand for the whole. 4 · Prāṇāyāmaप्राणायाम Regulation of the breath. Together, 3 and 4 discipline the bodyand regulate subtle energy flow, makingthe mind alert and more observant. 5 · Pratyāhāraप्रत्याहार Withdrawal of the senses fromtheir objects. External input is regulated so themind is not pulled about. 6 · Dhāraṇāधारणा Concentration — holding the mindon one thing, inner or outer. 7 · Dhyānaध्यान Meditation — an unbroken flow ofattention toward that object. 8 · Samādhiसमाधि Absorption — the distinction betweenthe attending mind and its objectno longer holds. Why the order matters The sequence is cumulative and the first two limbs come first for a reason: a mind agitated by its own conduct cannot be stilled by sitting still. Modern practice usually begins at limb three, which is a defensible entry point but not the one the text describes.
The physiological account

In any stress disorder, the parasympathetic mechanisms fail to damp the response to a stressful stimulus adequately. The claim made for yoga is that its practices influence autonomic regulation — restoring the balance between sympathetic and parasympathetic activity, and so preventing the accumulation of stress. This is a testable claim, and unlike most in this chapter, it has been tested.

19Tested at workप्रयोगपरीक्षा

A controlled study conducted inside an operating industrial plant, using a standard instrument — the kind of evidence this field needs more of.

Design of the Birla Cellulose burnout study Eighty-four volunteers split into a yoga group and a physical-exercise control group, both given equal hours, with burnout measured before and after using the Maslach Burnout Inventory. 84 volunteers managers at Birla Cellulose, a Grasim Industries unit Group I — yoga · n = 42 30 hours of practice — 75 minutes daily 25 hours of lectures on the philosophy of yoga 55 hours in total Group II — control · n = 42 Equal hours of ordinary physical exercise Equal hours of lectures on success factors in life, drawn from modern thought and not from yoga 55 hours in total Maslach Burnout Inventory, before and after a standard self-report instrument; paired t-test on the pre/post data
Adhia, Nagendra and Mahadevan, Vikalpa 35:2 (2010). Note what the design gets right: an active control matched for time and attention, rather than a do-nothing group; a validated instrument rather than an ad-hoc questionnaire; and a real workplace rather than a laboratory. Note also its limits — self-report, a modest sample, no blinding, and volunteers who chose to participate. It is a well-designed small study, not a definitive one, and that is how it should be cited.

The wider context is straightforward. Burnout — exhaustion, irritability, ineffectiveness, and the discounting of oneself and others, with hypertension, ulcers and cardiac problems following — is the endpoint of stress that has not been coped with, and it does not stay at work. Whatever one concludes about mechanisms, the question of whether a structured practice reduces it is answerable, and answering it is more useful than either asserting or denying that it does.

20Self-checkपरीक्षा

Check your reading

1 · What does svastha literally mean, and why does it matter?

The second line of the verse is not an afterthought; the definition fails without it. The parallel with the WHO's 1948 formulation is close.

2 · The doṣas are best described as —

Vāta from air and space, pitta from fire and water, kapha from water and earth. Each has a bodily region, a time of day and a season of life associated with it.

3 · What does Caraka's threefold analysis of causation cover?

The word dvyāśrayāṇām, “resting on both”, is what makes it a unified psychosomatic aetiology rather than two separate accounts.

4 · Why does the patient examination have ten items and the disease examination six?

Six of the ten patient items are about capacity and tolerance — constitution, habituation, food capacity, exertion capacity, psychological resilience, age — not about pathology at all.

5 · What is the correct position on bhasmas?

Long use does not establish safety, and dismissal ignores a genuine body of empirical pharmacology. Testing settles both.

Questions worth arguing about

Can a system with a different physiology be evaluated by trials designed for another?

The objection has force at the level of mechanism and none at the level of outcome. It is true that a trial testing a single molecule against a single diagnosis is a poor fit for a system that individualises treatment. It is not true that the outcomes are untestable: whether patients get better, and whether they come to harm, are the same questions regardless of the theory. Trial designs that accommodate individualised treatment exist — the difficulty is real and solvable, not principled.

Is the psychosomatic unity of Caraka's account a strength or a licence?

A strength when it prompts attention to sleep, stress and conduct as causes of physical illness — which is now mainstream. A licence when it is used to attribute any illness to the patient's own prajñāparādha, which shades quickly into blaming the sick for being sick. The framework does not decide between these uses; the practitioner does.

What has been lost in the modern popularisation of yoga?

Six limbs out of eight, mostly. What travels well is āsana, and to a lesser extent prāṇāyāma and meditation; what does not travel is the ethical foundation the text places first, and the graded structure in which each limb prepares the next. That is not necessarily fatal — a practice can be useful in fragments — but the claims made for the fragments are often the claims the text makes for the whole.
