Ayurveda arrives in most people's lives as a three question quiz on a website that announces, after eleven seconds, that they are a pitta. This is a shame, because the subject underneath is one of the most carefully worked out systems of medicine the ancient world produced, and it deserves better than that.
What follows is the classical material as the texts actually set it out, and an honest account of where the popular version goes wrong.
Where the material comes from
Three texts carry the weight. The Charaka Samhita, the great compendium of internal medicine; the Sushruta Samhita, which is chiefly surgical; and the Ashtanga Hridayam of Vagbhata, a later and beautifully compressed synthesis of the two. Together they are called the Brihat Trayi, the great triad. Everything reliable that is said about dosha comes from these, or from the commentarial tradition that grew around them. If a claim cannot be traced back to that literature or to the clinical practice that descends from it, treat it as somebody's opinion.
The three doshas
The word dosha is usually translated as humour, which is not quite right; it literally carries the sense of that which can become faulty or spoiled. The doshas are the functional principles that run the body. In health they are in a working equilibrium particular to you. In disease they have deviated. That second meaning is why the word means what it means.
They are formed from the five great elements (panchamahabhuta).
Vata
Air and space. Vata is everything that moves: nerve impulse, breath, peristalsis, circulation, the transmission of thought. The classical qualities attributed to it are dry, light, cold, rough, subtle and mobile. Its principal seat is below the navel, and the colon is its home. It has five functional divisions — prana, udana, samana, vyana and apana — each governing movement in a different region and direction. When vata is disturbed the classical picture is dryness, irregularity, cold extremities, disturbed sleep, wandering pain and an anxious, scattered mind.
Pitta
Fire, with water. Pitta is transformation: digestion, metabolism, body heat, the processing of what the eye sees and what the mind takes in. Its qualities are slightly oily, sharp, hot, light, liquid and spreading, and it has a characteristic smell. It sits between the navel and the heart, with the small intestine as its principal seat. Its five divisions are pachaka, ranjaka, sadhaka, alochaka and bhrajaka. Disturbed pitta shows as heat, acidity, inflammation, loose stool, sensitivity to sun, and a mind that is sharp, critical and quick to anger.
Kapha
Water and earth. Kapha is structure and cohesion — the fluid that lubricates a joint, the mucous that protects a membrane, the stability that holds a body and a temperament together. Its qualities are heavy, oily, cold, slow, smooth, dense and stable. It sits above the heart, with the chest and stomach as its seats, and divides into kledaka, avalambaka, bodhaka, tarpaka and shleshaka. Disturbed kapha shows as congestion, heaviness, sluggish digestion, water retention, and a mind that is calm to the point of inertia and reluctant to change.
Notice that none of these is a personality type. They are physiological functions that also have mental correlates. The popular literature has largely inverted this.
Prakriti and vikriti — the distinction that matters most
This is the part the quizzes almost always collapse, and collapsing it makes the whole system useless.
Prakriti is your constitution. Charaka describes it as fixed at conception, shaped by the state of the parents' reproductive material at that moment, the condition of the womb, the mother's diet and conduct during pregnancy, and the elemental influences on the forming embryo. It does not change afterwards. It is the baseline you were issued.
Vikriti — from vi, deviation, and kriti, formation — is what is happening now. It is the current departure from your baseline: the dosha that has increased, this season, in this job, after this illness.
Nearly all useful advice concerns vikriti, not prakriti. Knowing you are constitutionally vata is mildly interesting. Knowing that your vata is currently elevated after three months of travel and irregular meals is actionable. And the two frequently point in opposite directions — a person of kapha constitution in the middle of a pitta disturbance should be treated for the pitta, not fed a kapha-reducing regimen that will make things worse.
One further correction. Charaka does not describe three constitutional types; he describes seven — the three single-dosha types, the three dual combinations, and a balanced sama type. Most people are dual. The single-type person of the magazine article is comparatively rare.
Why the online quiz cannot settle this
I want to be careful here, because I am not saying the framework is worthless. I am saying the measuring instrument is poor, and this has been tested.
A study of interrater reliability in Ayurvedic diagnosis had fifteen registered Ayurvedic physicians, most of them holding an MD and with three to fifteen years of practice, examine the same twenty healthy young subjects. The average pairwise agreement on prakriti assessment, measured as kappa, was 0.28 — fair at best. Tongue examination came out at 0.17 and pulse at 0.07. Only twelve of a hundred and five doctor pairs agreed significantly on prakriti; on pulse, one pair did. The authors concluded that reliability was low across all three methods and called for standardised procedure and training.
Sit with that. If fifteen qualified physicians examining the same person face to face agree only fairly, a fourteen question form that asks whether you prefer summer or winter is not going to do better. Scoping reviews of the assessment tools published since have found the same problem from another direction: there is no agreed gold standard against which any questionnaire can be validated.
The practical conclusion is not to abandon the idea. It is to treat any dosha result — from a website or from a practitioner — as a working hypothesis to be tested against how you actually feel over months, and revised. Ayurveda's own method is observational and longitudinal. It was never meant to be settled in one sitting.
What it means for practice
Used carefully, the framework is a decent guide to how to adjust a practice you are already doing. Some reasonable rules of thumb, offered as tendencies rather than prescriptions.
- Elevated vata responds to warmth, regularity and grounding. Practise at the same time each day. Slower, steadier asana, held longer, with a stable base. Generous savasana. Warming, smooth breathing such as ujjayi. Be cautious with fast vinyasa, long fasting and cold rooms.
- Elevated pitta responds to cooling and to taking the competition out of the practice. Moderate effort, twists and forward folds, practice in cooler parts of the day, sheetali or sheetkari breathing. Avoid practising in heat, avoid measuring yourself against the mat beside you, and stop before exhaustion.
- Elevated kapha responds to stimulation. More vigour, more standing work, more variety, earlier rising. Kapalabhati and bhastrika where suitable and properly taught. Less sitting, less sleeping in the afternoon.
On food, the honest version is simpler than the charts suggest. Ayurveda's first concern is not which foods belong to which dosha but agni — digestive fire. Regular timings, the largest meal at midday when digestive capacity is highest, food that is warm and freshly cooked, no eating before the previous meal has been digested, and enough attention at the table to notice when you have had enough. That advice is unglamorous, it applies to everybody regardless of constitution, and it does more good than any list of permitted vegetables. Seasonal adjustment (ritucharya) and daily routine (dinacharya) come next. The dosha-specific food lists come last, and matter least, and are the only part most people ever read.
Honest limits
Ayurveda is a full medical system with its own long training, its own pharmacy and its own diagnostics. A month of yoga study, ours included, does not qualify anyone to practise it. What a yoga school can properly offer is an introduction to the principles, some sound guidance on routine and diet, and a referral to a qualified vaidya when something needs actual treatment.
Two cautions worth stating plainly. Ayurvedic medicines are medicines: some interact with pharmaceuticals, and some traditional preparations have been found to contain heavy metals, so buy only from reputable sources and tell your doctor what you are taking. And no dosha assessment substitutes for medical investigation of a real symptom. If something is wrong, get it looked at. The classical physicians would have said the same; they were, above all, clinicians.
