Dashavidha Pariksha: Tenfold Examination

Dashavidha pariksha is the tenfold examination of a person in Ayurveda: the ten-headed assessment by which the tradition gauges a person’s strength and fitness before it chooses any measure. The phrase joins dashavidha, tenfold, with pariksha, examination. Its ten heads range from the constitution a person is born with, through the quality and build of the tissues, to appetite, endurance and age. The purpose behind the whole is a single practical principle: that care must be fitted to the person, and that to fit it well the tradition must first read how much strength a body has to draw on. It is one of the most systematic pieces of classical assessment, set out in full by Charaka.

The source and purpose

The tenfold examination is given its classical statement in the Charaka Samhita, in the eighth chapter of the Vimanasthana, where the ten heads are named and described as the means of judging a person’s strength, or bala. The reasoning is that the same measure does not suit every body: a strong frame with sound tissues and a good appetite can bear what a depleted or delicate one cannot. To dose care safely, the tradition therefore examines the person as carefully as the imbalance, and the tenfold scheme is its checklist for doing so.

Prakriti and vikriti

The first two heads set the person against the moment. Prakriti is the constitution, the settled balance of the doshas a person is born with and carries through life; it tells the practitioner what is natural for this particular body. The ways the tradition reads it are described in How to Find Your Dosha, and rest on the theory of the three doshas set out in Tridosha: The Three Doshas. Vikriti is the present imbalance, the departure from that natural state that has brought the person to be examined. Reading the two together, the settled ground and the present departure, is the first act of the examination.

Sara, samhanana and pramana

The next three heads read the body itself. Sara is the excellence or quality of the tissues, graded from outward signs as a way of judging whether the dhatus are well-formed and resilient or frail; a person of good sara is held to have greater strength. Samhanana is the compactness of build, the firmness and evenness with which the body is put together, a well-knit frame being read as sturdier than a loose one. Pramana is proportion, the measurement of the body’s parts against the classical norms, taken as a further sign of soundness. Together these three read the physical stuff of the person.

Satmya and sattva

The following two heads turn to what suits the person and to the strength of the mind. Satmya is what a person is suited to and habituated to, the foods, routines and conditions that agree with them, which the tradition holds vary from person to person and must be respected in any plan of care. Sattva is the strength of mind, the steadiness and resolve with which a person meets discomfort and follows a course; a strong mind is read as able to bear more than a delicate one, whatever the state of the body.

Ahara shakti, vyayama shakti and vaya

The last three heads read capacity and stage of life. Ahara shakti is the capacity for food, both the ability to take it and the ability to digest it, and it is read closely alongside the state of the digestive fire; see Agni: The Digestive Fire. Vyayama shakti is the capacity for exertion, the endurance a person can sustain, taken as a plain measure of strength. Vaya is age, for the tradition holds that the body’s strength and the balance of its doshas shift across the seasons of life, childhood, the middle years and old age each having its own character.

Why the tenfold reading matters

The value of dashavidha pariksha is that it builds a rounded picture of a person’s strength from many angles at once. No single head decides the matter; a strong build with a weak appetite, or sound tissues with a delicate mind, tells a mixed story that only the ten together can express. From this picture the tradition judges bala, the overall strength, and fits the pace and force of any measure to it, giving less to the frail and more to the robust. It is, in essence, the classical way of asking how much a given body can safely bear.

This concern with strength is especially pointed where a strong or purifying measure is being weighed, for such measures ask a great deal of the body and suit only those with the strength to bear them. Here the tenfold examination becomes a safeguard: it lets the tradition see, before anything is undertaken, whether a person’s constitution, tissues, appetite, endurance and stage of life leave them fit for a demanding course or call instead for a gentle one. The examination is therefore not a formality but the ground on which the whole plan of care is built, and the classical texts return to it whenever the strength of the person must be matched to the strength of the measure.

The honest limit is that the tenfold examination is a framework of trained judgement, not a scored test. Each head is read qualitatively, from signs weighed by an experienced eye, and the heads are balanced against one another rather than added up. The grades of sara, the reading of sattva, the judging of satmya all rest on interpretation within the whole picture of the person. It is offered by the tradition as a disciplined way of assessing strength and suitability, applied by a qualified practitioner, and not as a self-administered measure.
