The ten questions behind Dashavidha Pariksha
A viva examiner asks, “What is the patient’s prakṛti?” You answer the constitution. Then comes the follow-up: “What about vikṛti, sāra, satmya, and sattva?” Many students know the ten names in Dashavidha Pariksha but cannot explain what information each one actually contributes.
That is the central difficulty: Dashavidha Pariksha is not merely a list to memorise. It is a structured way of asking whether the person’s baseline constitution, present disturbance, tissues, body build, adaptation, mental strength, intake capacity, exercise capacity, and age are understood well enough to interpret the illness correctly.
This article makes the sequence usable. It begins with the classical foundation, then separates the commonly confused parameters, explains what each parameter tells you, and ends with exam-ready formats. The aim is not to replace the mūla texts, but to make the organising logic of the tenfold examination visible.
Why Dashavidha Pariksha matters for your exams
Dashavidha Pariksha is a standard theory and viva topic in BAMS, especially under Charaka’s Vimāna Sthāna, clinical examination, and rogi-parīkṣā discussions. It also appears in short notes, long essays, matching questions, and AIAPGET-style one-liners; the ten names, their order, and the distinction between parameters are frequent scoring points.
A full-mark answer normally needs four things: the classical source, the ten factors in the correct order, the meaning and components of each factor, and a short statement of their practical interpretive value. The order itself is examinable, so do not rearrange the list casually.
Classical foundations of Dashavidha Pariksha
Charaka’s tenfold examination
The principal classical source is the Vimāna Sthāna of the Caraka Saṃhitā, particularly the discussion of examination of the patient in the eighth chapter, Rogabhīṣagjijñāsā or Rogabhīṣagjitiya Vimana. Charaka presents ten aspects through which the physician should examine the patient before deciding how the disease and its management should be understood.
The classical order is:
- Prakṛti — constitution or natural bodily-mind disposition
- Vikṛti — present pathological deviation
- Sāra — excellence or quality of the tissues
- Saṃhanana — compactness and structural integrity of the body
- Pramāṇa — bodily measurement and proportionality
- Sātmya — habituation and compatibility
- Sattva — mental strength or psychological resilience
- Āhāraśakti — capacity to ingest and digest food
- Vyayāmaśakti — capacity for physical exertion
- Vayaḥ — age or stage of life
Cakrapāṇidatta’s commentary on Charaka is important because it helps students read these as distinct examination domains rather than as ten interchangeable descriptions of “strength.” For example, sāra concerns the excellence of tissues, while saṃhanana concerns the compactness of the body; both may influence strength, but they are not synonyms.
Suśruta’s contribution
The Suśruta Saṃhitā discusses examination, bodily assessment, constitution, measurement, and the interpretation of physical features across its Sūtrasthāna and Śārīrasthāna. Suśruta’s emphasis on structural observation, bodily proportions, and the assessment of the person is especially useful for understanding why saṃhanana and pramāṇa cannot be collapsed into one category.
Suśruta also gives a strong anatomical and observational context to patient assessment. Thus, when writing about Dashavidha Pariksha, Charaka should be named as the principal source for the tenfold framework, while Suśruta may be cited for the broader classical examination of bodily structure, proportion, constitution, and physical features.
Vāgbhaṭa’s concise presentation
The Aṣṭāṅga Hṛdaya of Vāgbhaṭa preserves the practical spirit of patient examination in its Sūtrasthāna, especially in the early chapters dealing with the physician, patient, disease, and therapeutic decision-making. Vāgbhaṭa’s style is more compressed than Charaka’s, so the student should use the Aṣṭāṅga Hṛdaya to reinforce clinical application while using Charaka’s Vimāna Sthāna for the fullest tenfold enumeration.
Aruṇadatta and Hemādri, commentators on the Aṣṭāṅga Hṛdaya, are valuable when interpreting Vāgbhaṭa’s compact terminology. However, do not attribute a detailed commentarial explanation to them unless you have checked the relevant commentary. In an examination answer, a secure citation to the Aṣṭāṅga Hṛdaya Sūtrasthāna is better than an invented verse number or uncertain quotation.
What is common—and what must remain separate
The texts share an important principle: the disease is not interpreted in isolation from the person who bears it. Yet the ten parameters do not all measure the same thing. The following table is the quickest way to prevent category errors.
| Parameter | Main question | What it primarily describes |
|---|---|---|
| Prakṛti | What is the person’s baseline constitution? | Natural doṣic and bodily disposition |
| Vikṛti | What has changed now? | Present disease and doṣic disturbance |
| Sāra | How excellent are the tissues? | Dhātu quality or excellence |
| Saṃhanana | How well is the body structurally joined? | Compactness and bodily build |
| Pramāṇa | Are the body parts proportionate? | Measurement and symmetry |
| Sātmya | What has the person adapted to? | Habitual compatibility |
| Sattva | How strong is the mind? | Mental resilience and steadiness |
| Āhāraśakti | How much food can be handled? | Intake and digestion capacity |
| Vyayāmaśakti | How much exertion can be tolerated? | Exercise or exertional capacity |
| Vayaḥ | Which life stage is present? | Age and age-related predominance |
First principle: examine the person, not only the disease
The most useful organising idea is that Dashavidha Pariksha gives a patient-specific context to diagnosis and prognosis. Two people may present with the same disease name but differ in constitution, tissue excellence, mental strength, digestive capacity, or age. Those differences change the clinical interpretation of the same label.
This does not mean that every parameter independently diagnoses a disease. Rather, each parameter answers a different question about the rogi (patient). The examiner wants to see whether you understand this division of labour.
The one-line discriminator
Prakṛti is the person’s long-standing baseline; vikṛti is the present departure from that baseline.
This is the most important distinction in the entire topic. A person may have a vāta-pradhāna prakṛti (a constitution in which vāta is predominant) while currently showing a pitta-vikṛti (present aggravation or disturbance of pitta). Constitution is not the same as disease.
1. Prakṛti: the baseline constitution
Prakṛti means the individual’s natural constitution or inherent bodily disposition. In the Vimāna Sthāna of the Caraka Saṃhitā, prakṛti is linked with the condition established during development and is understood through the relative predominance of the doṣas and other constitutional features.
In study answers, you may describe the familiar constitutional categories—vāta, pitta, kapha, and their combinations—provided you make clear that the precise constitutional assessment is broader than assigning a quick body type. The physician considers enduring patterns of body, physiology, temperament, and susceptibility.
What prakṛti tells you
Prakṛti tells you the person’s starting point. It helps explain why individuals differ in appetite, activity, body structure, tolerance, and tendency toward particular imbalances. It is therefore a baseline variable, not a snapshot of the current complaint.
Do not write that prakṛti changes every day. Temporary changes belong to vikṛti. A person’s observed condition may be modified by season, age, diet, habits, and disease, but that does not make the constitutional category identical to the current disorder.
2. Vikṛti: the present deviation
Vikṛti means the current altered state, especially the present disturbance of doṣas, tissues, channels, or other disease factors. In Charaka’s patient examination, vikṛti directs attention from “What is this person normally like?” to “What has changed in this person now?”
Vikṛti includes the disease picture as it is actually manifest: the disturbed doṣa, affected dūṣya (body tissue or other substrate involved in disease), site, stage, strength, and associated signs. Its interpretation belongs with roga-parīkṣā (examination of disease) as well as with examination of the patient.
Why prakṛti and vikṛti must be read together
If the examiner asks for the diagnostic value of these two parameters, write the contrast explicitly:
| Feature | Prakṛti | Vikṛti |
|---|---|---|
| Time frame | Long-standing baseline | Present condition |
| Meaning | Natural constitution | Pathological deviation |
| Main use | Understand susceptibility and individual variation | Identify the current disease process |
| Exam phrase | “What is normal for this person?” | “What is abnormal now?” |
By way of modern correlation, prakṛti may be compared cautiously with a baseline phenotype and vikṛti with a current altered clinical state. This is only a teaching analogy, not an equation between Ayurvedic categories and modern biomedical diagnoses.
3. Sāra: excellence of the tissues
Sāra means essence, excellence, or the qualitative strength of the dhātus (body tissues). The Vimāna Sthāna of the Caraka Saṃhitā describes assessment of tissue excellence through features visible in the person. The commonly taught sequence follows the seven dhātus: tvak (skin), rakta (blood), māṃsa (muscle), medas (adipose tissue), asthi (bone), majjā (marrow or nervous tissue in interpretive usage), and śukra (reproductive tissue); sattva is also discussed as a distinct excellence in the classical presentation.
The important word is excellence, not merely quantity. A person can have a large body without every dhātu being of superior quality, just as a thin person cannot automatically be labelled low in all tissue qualities.
What sāra tells you
Sāra gives an idea of tissue quality, stability, endurance, appearance, and—in the classical framework—capacity to withstand disease. It contributes to assessment of bala (strength), but it is not identical to immediate physical strength.
The classical descriptions are observational. They refer to features such as clarity, lustre, firmness, stability, and other signs associated with the excellence of a particular tissue. When writing a short note, define sāra first, name the dhātu-based assessment, and then state that it indicates qualitative tissue status.
4. Saṃhanana: compactness of the body
Saṃhanana means compactness, firmness, or the quality with which the bodily components are joined. It is principally a structural assessment. The Caraka Saṃhitā discusses it in the tenfold examination, while Suśruta’s anatomical orientation in the Śārīrasthāna helps clarify why bodily structure and joining matter.
The classical concern is not simply “How heavy is the patient?” It is whether the bones, joints, muscles, and bodily parts are well formed, properly connected, and compact. A well-formed, compact body is classically associated with greater capacity to withstand strain than a poorly compacted one.
Saṃhanana versus pramāṇa
Saṃhanana asks how well the body is joined; pramāṇa asks whether its measurements and proportions are appropriate.
| Parameter | Assessment focus | Typical error |
|---|---|---|
| Saṃhanana | Compactness, firmness, structural joining | Treating it as body weight alone |
| Pramāṇa | Length, breadth, circumference, proportion | Treating any tall or short body as automatically abnormal |
A person may have good proportions but poor compactness, or a compact body with unusual proportions. That is why Charaka lists both separately.
5. Pramāṇa: measurement and proportion
Pramāṇa means measurement. In Dashavidha Pariksha it refers to assessment of bodily dimensions and proportionality. The Vimāna Sthāna of the Caraka Saṃhitā discusses bodily measurement as one of the factors used to understand the patient; Suśruta’s Śārīrasthāna provides a broader classical context for bodily proportions and structural assessment.
The purpose is not to reduce the person to a single number. Classical measurement considers the relation between body parts and overall bodily formation. In an answer, mention āṅgula-pramāṇa (measurement using the person’s finger-breadth as a unit) only when your syllabus or source specifically requires the traditional unit; do not invent numerical standards.
What pramāṇa tells you
Pramāṇa helps assess bodily proportion, development, and structural adequacy. It contributes to the estimation of strength and prognosis, but it cannot be interpreted apart from age, constitution, tissue excellence, and current disease.
By way of modern correlation, anthropometry offers a loose comparison because it also measures body dimensions and proportions. The comparison should remain clearly labelled as modern correlation: Ayurvedic pramāṇa belongs to a wider classical assessment of bodily formation and suitability, not merely to modern height-weight indices.
6. Sātmya: habituation and compatibility
Sātmya means suitability, habituation, or what is compatible with a particular person. The Caraka Saṃhitā, in the patient-examination discussion of the Vimāna Sthāna, treats sātmya as a factor that must be understood before judging the person’s capacity and condition.
Sātmya is often taught through food and lifestyle, but the concept is broader than liking something. It concerns adaptation: what the body and mind have become accustomed to and can tolerate or use without disturbance. A habitual food may be sātmyā (compatible) for one person because of long adaptation, while the same item may be unsuitable for another.
Sātmya versus āhāraśakti
Sātmya is about compatibility and habituation; āhāraśakti is about present capacity to take and digest food.
A person may be accustomed to a particular diet but currently have reduced digestive capacity. Conversely, someone may have strong digestion but poor adaptation to a newly introduced food. This is why the two parameters appear separately.
Sātmya is also discussed in relation to degrees of habituation in classical teaching: completely compatible, moderately compatible, or less compatible patterns may be distinguished according to the tradition and context. Avoid presenting one coaching-note classification as though every text uses identical terminology.
7. Sattva: mental strength
Sattva means mental strength, steadiness, or psychological resilience in this examination context. It should not be confused with sattva-guṇa (the quality of clarity in Sāṃkhya-derived philosophical terminology), although the words are related in the wider intellectual background.
Charaka’s Vimāna Sthāna includes sattva among the factors used to judge the patient. The assessment concerns how the person responds to discomfort, fear, stress, disease, unpleasant procedures, and difficult circumstances. Classical teaching commonly describes higher, moderate, and lower levels of mental strength.
What sattva tells you
Sattva helps the physician understand the patient’s psychological response to disease and the person’s capacity to tolerate distress. It is not a moral ranking. “Lower sattva” in an examination answer should mean reduced mental endurance or resilience in the relevant context, not that the person is inferior.
Do not merge sattva with intelligence, personality, or willingness to follow instructions. Those may interact with mental strength, but they are not automatic synonyms.
8. Āhāraśakti: capacity for food and digestion
Āhāraśakti means the power related to food intake and digestion. In the tenfold examination, Charaka distinguishes this from general body strength. It has two practical dimensions: abhyavaharaṇa-śakti (capacity to take food) and jaraṇa-śakti (capacity to digest food).
This distinction is highly examinable. A person may be able to consume a substantial quantity but digest it poorly, or may digest efficiently but be unable to take much food. Therefore, do not define āhāraśakti only as “appetite.” Appetite is one observable component, not the complete parameter.
What āhāraśakti tells you
Āhāraśakti helps estimate digestive capacity and the person’s ability to process nourishment. It also assists in judging the person’s overall functional reserve in the classical framework. The terms sama (balanced), viṣama (irregular), tīkṣṇa (sharp), and manda (weak or slow) are often used in discussions of agni (digestive and metabolic fire), but do not automatically substitute agni classification for the full tenfold parameter.
By way of modern correlation, food tolerance and digestive symptoms may provide a rough contemporary analogy. They do not directly equal Ayurvedic āhāraśakti or agni.
9. Vyāyāmaśakti: capacity for exertion
Vyayāmaśakti means the capacity to perform physical exertion or exercise. The Caraka Saṃhitā includes it as a separate component of patient assessment because a person’s tolerance for activity provides information not captured by body size or tissue appearance alone.
Classically, exertion is judged through signs such as the point at which fatigue, breathlessness, sweating, or other strain appears. The precise interpretation depends on the person’s constitution, season, age, habituation, and present disease. Therefore, “can perform heavy exercise” should not be treated as a universal standard independent of context.
Āhāraśakti versus vyāyāmaśakti
Āhāraśakti measures handling of nourishment; vyāyāmaśakti measures tolerance of exertion.
| Parameter | Immediate domain | Why it matters |
|---|---|---|
| Āhāraśakti | Taking and digesting food | Indicates digestive and nutritional capacity |
| Vyayāmaśakti | Physical effort and recovery from effort | Indicates functional exertional capacity |
The two may correlate, but they are not interchangeable. A patient may have reasonable digestion but poor exercise tolerance during an acute illness, or good physical conditioning with an impaired current digestive state.
10. Vayaḥ: age and stage of life
Vayaḥ means age or stage of life. In the Caraka Saṃhitā and other classical Ayurvedic texts, age is not merely a calendar number; it is a physiological context. The Aṣṭāṅga Hṛdaya Sūtrasthāna also presents the familiar doṣic predominance of life stages: kapha in childhood, pitta in maturity, and vāta in old age.
Different texts and teaching traditions may vary in the exact numerical boundaries assigned to childhood, adulthood, and old age. The safe examination approach is to name the broad stages and cite the text or syllabus convention being followed rather than presenting uncertain numbers as universal.
What vayaḥ tells you
Age modifies constitution, tissue development, digestive capacity, strength, mental response, and disease expression. It therefore acts as a contextual parameter for interpreting the other nine. A child, an adult, and an older person cannot be assessed with exactly the same expectations of bala, agni, or exertional capacity.
How the ten parameters work together
The ten factors become most useful when read as a sequence rather than as isolated definitions. A practical study scaffold is:
- Prakṛti — establish the baseline.
- Vikṛti — identify the present disturbance.
- Sāra — assess tissue excellence.
- Saṃhanana — assess structural compactness.
- Pramāṇa — assess bodily proportion.
- Sātmya — identify habituation and compatibility.
- Sattva — assess mental strength.
- Āhāraśakti — assess intake and digestion capacity.
- Vyayāmaśakti — assess exertional capacity.
- Vayaḥ — place the findings in the age context.
The order itself is examinable. In a long answer, reproduce it before expanding the individual parameters. The order also moves from baseline and pathology through structure and adaptation to functional strength and age, giving the list an internal logic.
A compact interpretive matrix
| Domain | Parameters | Central idea |
|---|---|---|
| Baseline and disease | Prakṛti, vikṛti | Normal constitution versus present alteration |
| Tissue and structure | Sāra, saṃhanana, pramāṇa | Quality, compactness, and proportion |
| Adaptation and mind | Sātmya, sattva | Compatibility and psychological resilience |
| Functional capacity | Āhāraśakti, vyāyāmaśakti | Food handling and exertional ability |
| Life context | Vayaḥ | Age-related interpretation |
Applied understanding: how a student should read a case
This is an applied learning illustration, not medical advice. Imagine a case description of an older person with a long-standing vāta-dominant constitution, a current pitta-related complaint, moderate tissue excellence, good body compactness, limited food intake, irregular digestion, low exercise tolerance, and strong mental resilience.
A weak answer merely repeats ten labels. A stronger answer interprets the case parameter by parameter: prakṛti describes the baseline; vikṛti describes the current departure; sāra describes tissue quality; saṃhanana describes structure; āhāraśakti and vyāyāmaśakti describe two different capacities; and vayaḥ modifies the interpretation because the person is older.
Notice that no single feature decides the whole case. A compact body does not prove excellent tissue quality. Strong mental resilience does not prove strong digestion. Familiarity with a food does not prove high āhāraśakti. Dashavidha Pariksha is valuable precisely because it prevents one visible feature from standing in for the entire person.
Memory aids and common confusions
A usable memory scaffold
Use the initials in three groups:
- P V S S P — Prakṛti, Vikṛti, Sāra, Saṃhanana, Pramāṇa: baseline, disease, tissue, structure, measurement.
- S S Ā V V — Sātmya, Sattva, Āhāraśakti, Vyāyāmaśakti, Vayaḥ: adaptation, mind, food, exertion, age.
The phrase “Baseline–Disease; Tissue–Structure–Measure; Adaptation–Mind; Food–Effort–Age” is often easier to recall than a letter-only mnemonic.
Three one-line corrections
- Prakṛti versus vikṛti: prakṛti is the stable baseline; vikṛti is the present disturbance.
- Sāra versus saṃhanana: sāra is tissue excellence; saṃhanana is bodily compactness.
- Sātmya versus āhāraśakti: sātmya is habituation or compatibility; āhāraśakti is the capacity to take and digest food.
Two further distinctions are worth remembering:
- Pramāṇa versus saṃhanana: pramāṇa concerns proportion and measurement; saṃhanana concerns structural joining and compactness.
- Sattva versus vyāyāmaśakti: sattva concerns mental resilience; vyāyāmaśakti concerns physical exertional capacity.
How examiners ask Dashavidha Pariksha
Long-answer stem
“Describe Dashavidha Pariksha according to Charaka.”
For full marks, cite the Vimāna Sthāna of the Caraka Saṃhitā, write all ten parameters in the correct order, define each, and explain the diagnostic or prognostic information each provides. Add a comparison of at least two commonly confused pairs.
Short-note stem
“Write a short note on sāra and saṃhanana.”
Define both terms, distinguish tissue excellence from bodily compactness, mention their relevance to strength, and cite Charaka; Suśruta may be added for the structural context of bodily examination.
One-liner or MCQ angle
“Which parameter assesses the capacity to take and digest food?”
Answer: āhāraśakti. If the question asks for its components, write abhyavaharaṇa-śakti and jaraṇa-śakti rather than answering only “appetite.”
Assertion or matching angle
“Prakṛti is the present disease state; vikṛti is the natural constitution.”
Both parts are reversed. The correct statement is: prakṛti is the baseline constitution, while vikṛti is the current pathological deviation.
Study Takeaways
- Dashavidha Pariksha is the tenfold examination of the patient, principally presented in Charaka’s Vimāna Sthāna.
- Memorise the exact order: prakṛti, vikṛti, sāra, saṃhanana, pramāṇa, sātmyа, sattva, āhāraśakti, vyāyāmaśakti, vayaḥ.
- Prakṛti answers “What is normal for this person?”; vikṛti answers “What has changed now?”
- Sāra is qualitative tissue excellence, not simply body size or weight.
- Saṃhanana concerns compactness and structural joining; pramāṇa concerns measurement and proportion.
- Sātmya is habituation or compatibility, whereas āhāraśakti is food intake and digestion capacity.
- Sattva measures mental resilience in the examination context; vyāyāmaśakti measures tolerance of physical exertion.
- Vayaḥ modifies the interpretation of every other parameter because age changes physiology, strength, and disease expression.
FAQ: Dashavidha Pariksha questions students search
What is Dashavidha Pariksha in Ayurveda?
Dashavidha Pariksha is the tenfold examination of the patient described principally in the Vimāna Sthāna of the Caraka Saṃhitā. It examines constitution, current disturbance, tissue quality, body structure, measurement, habituation, mental strength, food capacity, exercise capacity, and age.
What are the ten components of Dashavidha Pariksha?
The ten are prakṛti, vikṛti, sāra, saṃhanana, pramāṇa, sātmya, sattva, āhāraśakti, vyāyāmaśakti, and vayaḥ. Their classical order should be retained in university and AIAPGET answers.
What is the difference between prakriti and vikriti?
Prakṛti is the person’s natural, long-standing constitution. Vikṛti is the present pathological deviation or altered state; it may differ from the person’s constitutional predominance.
What is the difference between sara and samhanana?
Sāra assesses the excellence or quality of the tissues. Saṃhanana assesses the compactness, firmness, and structural joining of the body; therefore, tissue quality and body build are related but distinct.
Is aharashakti the same as agni?
No. Āhāraśakti is the capacity to take and digest food and includes intake as well as digestion. Agni is the digestive and metabolic fire, a broader Ayurvedic concept whose state contributes to—but does not simply equal—the assessment of āhāraśakti.
