Introduction
Dashavidha Pariksha — the tenfold examination — is the comprehensive diagnostic framework described in the Charaka Samhita (Vimana Sthana, Chapter 8) for assessing the patient and the disease. While Ashtasthana Pariksha focuses on the eight physical examination methods (pulse, tongue, urine, etc.), Dashavidha Pariksha takes a broader view, examining the patient’s constitution, their current state of imbalance, the quality of their tissues, and their capacity for treatment. It is the framework that guides the practitioner in determining prognosis, selecting treatment intensity, and planning the duration of therapy.
The ten examination criteria are: Prakriti (constitution), Vikriti (state of imbalance), Sara (tissue quality/excellence), Samhanana (body proportion and structure), Pramana (body measurements), Satmya (adaptability/habitual suitability), Satva (mental constitution/psychological strength), Ahara Shakti (digestive capacity), Vyayama Shakti (exercise capacity), and Vaya (age).
For the student, Dashavidha Pariksha represents the most complete diagnostic framework in Ayurveda. It moves beyond simple dosha identification to assess the patient’s overall physical, mental, and physiological status. It provides the information needed to make a prognosis and to design a treatment plan that is appropriate to the patient’s strength and capacity.
For the patient, the tenfold examination may take one to two hours and involves detailed questioning about all aspects of their constitution, health history, diet, digestion, exercise habits, and mental state. It is a thorough, holistic assessment that leaves no important factor unexamined.
For the practitioner, Dashavidha Pariksha is the essential tool for determining the intensity and duration of treatment. A patient with strong sara (tissue quality), robust samhanana (body structure), and high satva (mental strength) can tolerate aggressive therapies like panchakarma. A patient with weak tissues, poor structure, and low mental resilience requires gentle, gradual treatment over a longer period.
Prakriti: Constitutional Assessment
Prakriti examination is the assessment of the patient’s inherent constitution — the doshic pattern established at conception that remains stable throughout life. Prakriti is determined by the predominance of the doshas at the time of conception and is influenced by the Shukra (sperm) and Shonita (ovum) of the parents, the condition of the mother’s uterus, the season, and the mental state of the parents at conception.
The assessment of Prakriti involves: physical characteristics (body frame, weight, height, skin texture, hair quality, nail shape, eye appearance, teeth structure); physiological characteristics (appetite, digestion, elimination, sleep patterns, temperature preference); psychological characteristics (memory, emotional tendencies, mental speed, sleep quality, temperament); and behavioral characteristics (speech patterns, movement style, social preferences, work habits).
Vata Prakriti individuals tend to be thin, light-boned, with dry skin and hair, variable appetite and digestion, light and interrupted sleep, and a creative, quick, anxious mental tendency. Pitta Prakriti individuals tend to be medium-built, with warm, fair skin that may be prone to freckles or moles, strong appetite, sharp digestion, warm body temperature, and a sharp, intelligent, competitive mental tendency. Kapha Prakriti individuals tend to be heavily built, with smooth, oily, pale skin, thick hair, steady appetite, slow digestion, heavy sleep, and a calm, stable, sometimes lethargic mental tendency.
The assessment of Prakriti is important because it establishes the patient’s baseline. Treatment is designed not to change the Prakriti (which is fixed) but to restore the Vikriti (the current imbalance) toward the Prakriti. A Vata Prakriti person will always have some Vata qualities, and the goal of treatment is not to eliminate Vata but to keep it within the healthy range for that individual.
Vikriti: State of Imbalance
Vikriti examination is the assessment of the patient’s current state of imbalance — the deviation of the doshas from their Prakriti baseline. Vikriti is dynamic and changes with diet, lifestyle, season, age, and treatment. The comparison of Vikriti to Prakriti provides the most clinically useful information for treatment planning.
The assessment of Vikriti involves: the identification of which doshas are increased, decreased, or disturbed; the determination of whether the dosha disturbance is in the stage of accumulation (chaya), aggravation (prakopa), spread (prasara), localization (sthana samshraya), manifestation (vyakti), or complication (bheda); the identification of the specific tissues and channels involved; the assessment of whether the dosha is sama (with ama) or nirama (without ama); and the comparison of the current Vikriti to the patient’s Prakriti to determine the degree of deviation from their healthy baseline.
The comparison of Prakriti and Vikriti is essential for prognosis. A Vata Prakriti patient with a Vata Vikriti has a doshic imbalance that is consistent with their constitution — this is generally easier to treat than a Vata Prakriti patient with a Pitta Vikriti, because the treatment must address a dosha (Pitta) that is not natural to the patient’s constitution.
Sara: Tissue Quality
Sara means “essence” or “excellence” and refers to the quality of each of the seven tissues (dhatus). The assessment of Sara is the assessment of tissue excellence — the degree to which each tissue is functioning at its optimal level. Sara is determined by genetic factors, diet, digestion, and the cumulative effects of lifestyle over time.
There are eight types of Sara: Twak Sara (skin excellence), Rakta Sara (blood excellence), Mamsa Sara (muscle excellence), Meda Sara (fat tissue excellence), Asthi Sara (bone excellence), Majja Sara (marrow/nervous tissue excellence), Shukra Sara (reproductive tissue excellence), and Sattva Sara (mental excellence).
Twak Sara is assessed by the quality of the skin: smooth, soft, radiant, well-moisturized, with fine hair and a clear complexion indicates excellent skin quality. Rakta Sara is indicated by the color of the skin, lips, nails, tongue, and eyes: a healthy pink-red color without discoloration indicates excellent blood quality. Mamsa Sara is indicated by well-developed, firm muscles and well-covered bones. Meda Sara is indicated by proper fat distribution, not too much and not too little, with a healthy lustrous appearance. Asthi Sara is indicated by well-formed, strong bones, teeth, and nails. Majja Sara is indicated by well-filled, rounded joints and healthy, lustrous eyes. Shukra Sara is indicated by a pleasant appearance, good vitality, and a natural radiance that attracts others. Sattva Sara is indicated by good memory, intelligence, self-control, courage, and mental stability.
The assessment of Sara is important for prognosis. Patients with excellent Sara (especially multiple tissues) have a favorable prognosis and can tolerate aggressive treatment. Patients with poor Sara require gentle, nourishing treatment over a longer period.
Samhanana: Body Proportion and Structure
Samhanana refers to the structural integrity and proportion of the body — the quality of the body’s architecture. It is assessed by examining the arrangement of the bones, the quality of the joints, the proportion of the body parts, and the overall structural harmony.
A person with excellent Samhanana has well-proportioned body parts, strong and well-formed bones, firm and properly aligned joints, a well-built frame with good symmetry, and a compact, solid appearance. A person with poor Samhanana has disproportionate body parts, weak or poorly formed bones, lax or poorly aligned joints, a loose, poorly compacted frame, and an irregular or asymmetrical appearance.
Samhanana is directly related to the prognosis. A person with excellent Samhanana has a strong structural foundation and can tolerate physical therapies, panchakarma, and vigorous exercise. A person with poor Samhanana requires gentle treatment and may be more susceptible to injury from physical therapies.
Pramana: Body Measurements
Pramana refers to the measurement of the body — the height, width, circumference, and length of various body parts, as well as the weight and overall proportions. Ayurveda describes specific ideal measurements for each body part based on the individual’s own fingers (angula pramana), but the more clinically relevant assessment is whether the measurements are proportionate and appropriate for the individual’s constitution.
The assessment of Pramana involves: measurement of height, weight, and body mass; measurement of specific body parts (head circumference, chest circumference, arm length, leg length); assessment of proportionality — whether the upper and lower body are well-proportioned; and comparison of current measurements to ideal measurements for the individual’s constitution.
Excessive Pramana (overweight, excessively large body parts) indicates Kapha excess. Deficient Pramana (underweight, excessively small body parts) indicates Vata excess. The assessment of Pramana helps to confirm the doshic assessment made through Prakriti and Vikriti examination.
Satmya: Adaptability and Habitual Suitability
Satmya refers to the substances and practices to which the individual has become adapted — the foods, habits, and environmental conditions that are suitable for them based on long-term usage. Satmya is the principle of habituation: the body adapts to whatever it is regularly exposed to, and what is suitable for one person may not be suitable for another.
The assessment of Satmya involves: dietary adaptability — which foods, tastes, and food groups the person can digest comfortably; climate adaptability — which climates and weather conditions the person tolerates well; activity adaptability — which physical activities and exercise the person can perform comfortably; and lifestyle adaptability — which daily routines and habits suit the person.
Satmya is important for treatment planning. A patient who has been habituated to a particular diet or lifestyle for many years will not tolerate sudden, radical changes. The practitioner must consider the patient’s Satmya when designing dietary and lifestyle recommendations, making gradual changes that the patient can adapt to over time.
Satva: Mental Constitution
Satva refers to the mental constitution — the strength, clarity, and stability of the mind. Satva is assessed through the observation of the patient’s mental and emotional qualities: memory, concentration, courage, emotional stability, self-control, and the ability to tolerate stress.
A person with excellent Satva has a strong, clear, stable mind. They have good memory and concentration, courage in the face of difficulty, emotional stability under stress, self-control and discipline, and a positive, optimistic outlook. A person with moderate Satva has variable mental strength — sometimes strong and clear, sometimes weak and disturbed. A person with low Satva has a weak, unstable mind with poor memory and concentration, fearfulness and lack of courage, emotional lability and reactivity, poor self-control, and a negative, pessimistic outlook.
The assessment of Satva is critical for treatment planning. A person with low Satva cannot tolerate aggressive therapies, bitter or unpleasant medicines, or significant lifestyle changes. They require gentle, supportive treatment with a strong emphasis on psychological support, counseling, and the use of medhya rasayanas (mind-nourishing herbs).
Ahara Shakti: Digestive Capacity
Ahara Shakti refers to the capacity to digest food. It is assessed in two ways: by the quantity of food the person can digest (abhyavaharana shakti) and by the quality and efficiency of the digestion (jarana shakti).
The assessment of Ahara Shakti involves: appetite — whether it is strong, weak, or variable; the quantity of food the person can eat comfortably; the speed of digestion — how long after a meal the person feels hungry again; the quality of digestion — whether digestion is complete and comfortable or accompanied by gas, bloating, burning, or heaviness; and the consistency and regularity of bowel movements.
Ahara Shakti is directly related to the state of Agni. A person with strong Ahara Shakti has strong Agni and can digest a wide range of foods. A person with weak Ahara Shakti has weak Agni and requires easily digestible foods and digestive support. The assessment of Ahara Shakti guides the dietary prescription and the use of deepana-pachana herbs.
Vyayama Shakti: Exercise Capacity
Vyayama Shakti refers to the capacity for physical exercise. It is assessed by the person’s ability to perform physical work, their endurance, and their response to exertion.
The assessment of Vyayama Shakti involves: the person’s ability to perform their usual physical activities without fatigue; their capacity for additional exercise; and their response to exercise — whether they feel energized or exhausted after exertion.
Vyayama Shakti is an important indicator of overall strength and vitality. A person with strong Vyayama Shakti has good physical reserves, strong Agni, and good tissue quality. A person with weak Vyayama Shakti has depleted reserves, weak Agni, and poor tissue quality. The assessment of Vyayama Shakti guides the prescription of exercise and physical therapies.
Vaya: Age
Vaya refers to the age of the patient, which is assessed in three categories: childhood (bala avastha, up to age 30), adulthood (madhyama avastha, ages 30 to 60), and old age (jirna avastha, age 60 and above). Each age period has a characteristic doshic predominance: Kapha predominates in childhood, Pitta in adulthood, and Vata in old age.
The assessment of Vaya involves: the chronological age; the biological age (how old the person appears and functions); and the doshic stage of life — whether the person is in the Kapha, Pitta, or Vata period of life.
The age of the patient is important for treatment planning. Children require gentle therapies with sweet-tasting medicines. Adults can tolerate stronger therapies and panchakarma. The elderly require gentle, nourishing therapies that support Vata balance.
The ten examinations are not assessed in isolation. The practitioner integrates the findings from all ten assessments into a comprehensive picture of the patient’s health. A young patient (Vaya) with strong Sara and Samhanana, good Ahara Shakti and Vyayama Shakti, and excellent Satva can tolerate aggressive treatment and has a favorable prognosis. An elderly patient with weak Sara, poor Samhanana, low digestive and exercise capacity, and low Satva requires gentle, gradual treatment and has a guarded prognosis.
The integration of the ten examinations guides all clinical decisions: the choice of treatment intensity, the duration of therapy, the selection of medicines (strong or mild, bitter or sweet), the type of panchakarma (full or modified), and the frequency of follow-up. Dashavidha Pariksha is not merely a diagnostic framework — it is a prognostic framework that guides the entire therapeutic process.
Conclusion
Dashavidha Pariksha is the most comprehensive diagnostic framework in Ayurveda. It assesses the patient at ten different levels — from their fixed constitutional pattern (Prakriti) through their current state of imbalance (Vikriti), the quality of their tissues (Sara), their structural integrity (Samhanana), their physical measurements (Pramana), their adaptability (Satmya), their mental strength (Satva), their digestive capacity (Ahara Shakti), their physical endurance (Vyayama Shakti), and their stage of life (Vaya).
The purpose of this comprehensive assessment is not academic. It is practical. It provides the information the practitioner needs to make a prognosis, to select the appropriate treatment intensity, and to design a treatment plan that is appropriate to the individual patient’s capacity. The patient with strong tissues, good structure, and robust digestion can tolerate the strong therapies that may be needed to eliminate deep-seated disease. The patient with weak tissues, poor structure, and compromised digestion requires gentle, gradual treatment that supports and restores rather than purifying and eliminating.
Dashavidha Pariksha embodies the fundamental principle of Ayurveda: that treatment must be tailored to the individual. It is the framework that makes personalized medicine possible, not as a slogan but as a systematic, reproducible clinical methodology.
