Before an Ayurvedic clinician prescribes a herb, recommends a purification procedure, or designs a diet plan, the patient is examined. In classical Ayurveda, this examination is not limited to naming a disease; it evaluates the person’s constitution, present imbalance, tissue strength, adaptability, mental endurance, digestive capacity, work capacity, and age-stage so that treatment can be matched to both the disorder and the patient’s strength.

“Tasmād āturaṃ parīkṣeta prakṛtitaśca, vikṛtitaśca, sārataśca, saṃhananataśca, pramāṇataśca, sātmyataśca, sattvataśca, āhāraśaktitaśca, vyāyāmaśaktitaśca, vayastaśceti.”
Therefore the patient should be examined through constitution, morbidity, tissue essence, compactness, measurement, suitability, mental strength, food capacity, exercise capacity, and age.

This ten-fold patient assessment, commonly called Dasha Vidha Pariksha or Dashavidha Atura Pariksha, is described in Charaka Samhita, Vimana Sthana, chapter 8. Its central purpose is to understand bala, the strength of the patient, and the degree of morbidity before deciding the potency, intensity, sequence, and suitability of treatment.

The Ten Examination Parameters

The ten parameters work together as a clinical map: Prakriti shows the constitutional baseline, Vikriti shows the present disturbance, and the remaining parameters show how much intervention the patient can safely tolerate and what kind of support is most appropriate.

1. Prakriti (Constitutional Type)

Prakriti is the patient’s constitutional pattern, formed from early developmental factors and expressed through predominance of Vata, Pitta, Kapha, combined doshic patterns, or balanced dhatu. Classical assessment of Prakriti observes body build, skin, hair, appetite, thirst, digestion, sleep, speech, movement, emotional tendencies, stamina, and the habitual way a person responds to food, climate, stress, and exertion. It provides the baseline against which present imbalance is interpreted.

2. Vikriti (Current Pathological State)

Vikriti is the present disorder or deviation from equilibrium. Charaka describes its assessment through the strength of causative factors, dosha, dushya, constitution, place, time, strength, and symptoms. In clinical use, this means that the same outward complaint may require different treatment when the underlying dosha, tissue involvement, disease stage, and patient strength differ.

3. Sara (Tissue Excellence)

Sara means the excellence or essence of body tissues and mind. Charaka describes eight forms: Tvak, Rakta, Mamsa, Meda, Asthi, Majja, Shukra, and Sattva sara. This assessment prevents the clinician from judging strength merely by size; a lean person may still possess strong tissue essence, while a large body may not necessarily indicate good bala.

4. Samhanana (Body Compactness)

Samhanana assesses the compactness and integration of the body. A well-compacted body is described as having well-arranged bones, well-bound joints, and properly placed muscle and blood tissue. In practice, this helps the physician estimate structural strength, joint stability, and the patient’s capacity to tolerate treatments that require physical resilience.

5. Pramana (Measurement and Proportion)

Pramana assesses bodily measurement and proportion, traditionally by anguli pramana, the patient’s own finger-width unit. Classical Ayurveda uses this person-specific method to evaluate proportion rather than relying only on absolute weight. In modern clinical settings, proportional assessment may be complemented by measurements such as waist-to-height ratio, waist circumference, and body composition, while keeping the Ayurvedic purpose focused on individualized proportion and strength.

6. Satmya (Suitability and Adaptability)

Satmya is what has become suitable through consistent use. Charaka defines it as that which, when used continually, becomes wholesome to the person. This includes habitual foods, daily routines, climate, oils, milk, ghee, meat soup, rasas, and lifestyle patterns. A prescription that ignores Satmya may be theoretically correct yet practically destabilizing; gradual transition is often safer than abrupt removal of long-established habits.

7. Sattva (Mental Strength and Resilience)

Sattva here refers to mental strength. Charaka classifies it as pravara (superior), madhyama (moderate), and avara (inferior). A person with strong Sattva can remain steady even under severe distress; a person with weaker Sattva may be disturbed even by milder discomfort. This directly influences how much explanation, reassurance, preparation, and treatment intensity are appropriate.

8. Ahara Shakti (Food and Digestive Capacity)

Ahara Shakti is assessed through two capacities: Abhyavaharana Shakti, the capacity to take food, and Jarana Shakti, the capacity to digest it. Strength and longevity are described as dependent on food, so the clinician must know whether the patient can tolerate regular meals, digest without heaviness, assimilate nourishment, and safely receive oral medicines.

9. Vyayama Shakti (Exercise and Work Capacity)

Vyayama Shakti is assessed through Karma Shakti, the capacity for work. It indicates whether the patient’s practical strength is inferior, moderate, or superior. This parameter guides exercise advice, recovery pacing, and the suitability of physically demanding therapies, because the same regimen that strengthens one patient may exhaust another.

10. Vaya (Age and Life-Stage Factors)

Vaya is age understood as bodily stage, not merely a number. Charaka divides it broadly into childhood, middle age, and old age. Childhood is associated with immature dhatu and Kapha predominance; middle age with developed strength and Pitta predominance; old age with gradual decline of tissues, senses, strength, memory, and Vata predominance. Treatment intensity, diet, cleansing, and rejuvenation must be adjusted accordingly.

Dasha Vidha Pariksha: Clinical Quick Reference

This quick reference summarizes the role of each parameter in bedside decision-making. It is not a substitute for a full consultation, but it shows why Dasha Vidha Pariksha is more than a checklist: each point modifies diagnosis, treatment strength, diet, procedure selection, and prognosis.

Clinical Integration: How the Ten Parameters Work Together

Consider a patient who presents with chronic tiredness, heaviness after meals, poor enthusiasm, and repeated seasonal congestion. The physician does not stop at the symptom label. Prakriti may show a Vata-Pitta baseline, Vikriti may show Kapha increase with weak digestion, Sara may reveal reduced tissue resilience, Satmya may show long habituation to cold foods and irregular meals, Sattva may show moderate stress tolerance, Ahara Shakti may show poor digestion despite appetite, Vyayama Shakti may be low, and Vaya may place the patient in a stage where depletion and aggravation must both be considered.

From that assessment, the first priority may be to kindle digestion gently, reduce heaviness, correct habits gradually, rebuild daily rhythm, and introduce exercise in a dose the patient can actually sustain. Rasayana or stronger procedures would be considered only when digestion, strength, and suitability support them. This is the practical value of Dasha Vidha Pariksha: it does not merely ask what disorder is present; it asks what kind of person is carrying it and what level of treatment that person can safely receive.

The ten-fold examination is therefore not a decorative questionnaire. It is a disciplined clinical method that connects diagnosis, prognosis, diet, medicine strength, procedure selection, and patient safety. It is best learned through classical study, supervised observation, and repeated practice under a qualified teacher.
