# pramāṇa (प्रमाण) > Canonical version of this page: https://nighantu.ageayurveda.com/lexicon/pramana/ An Ayurvedic technical term, rendered into English in 6 different ways. The renderings do not agree, and the difference between them changes what the term is taken to mean. ## Identification | Field | Value | | --- | --- | | Transliteration | pramāṇa | | Devanagari | प्रमाण | | Also written | pramāṇam, pramāṇaḥ, śarīrapramāṇa | | Category, as gathered | prakriti | | Grouped under | Regimen and constitution | | Classical citations | 5 | | Citations checked | 2026-10-08 | ## How it is translated, and whether the translation holds Each rendering is given with the source that uses it. The assessment is ours. ### Body measurements WHO International Standard Terminologies on Ayurveda (2022) · ITA-3.1.5 (pramāṇam) · standard 'Measurements of the whole or part of the body usually described in proportions based on the width of an individual's fingers.' The word 'individual's' is crucial: the unit is the patient's own finger, so the scale is relative.

WHO documents the homonym explicitly, in two chapters, with two genders of the same stem.

Kaviratna (1896-1913) · Vimanasthana 8 · translation His word for the examination item. ### the exact measures of the different limbs and members of the body Sushruta Samhita, tr. Bhishagratna (1907-1916) · Sutrasthana XXXV · translation Descriptive rather than terminological, and explicitly tied to prognosis of lifespan. ### anthropometry Indian Ayurvedic college usage · textbook · our paraphrase of the source, not its words Defensible for the content, but it imports a population-normed discipline where the classical unit is the patient's own finger. ## The classical passages ### Charaka Samhita Vimanasthana 8:117, checked against the source > pramāṇataścēti śarīrapramāṇaṁ punaryathāsvēnāṅgulipramāṇēnōpadēkṣyatē utsēdhavistārāyāmairyathākramam| … kēvalaṁ punaḥ śarīramaṅguliparvāṇi caturaśītiḥ| tatrāyurbalamōjaḥ sukhamaiśvaryaṁ vittamiṣṭāścāparē bhāvā bhavantyāyattāḥ pramāṇavati śarīrē; viparyayastvatō hīnē'dhikē vā||117|| Sanskrit mūla · https://www.carakasamhitaonline.com/index.php/Rogabhishagjitiya_Vimana Measurement is in the patient's own aṅgula, by height, breadth and length; the whole body is 84 aṅgula-parvas. Longevity, strength, ojas, happiness and wealth are said to depend on correct proportion, and the reverse follows for a body under OR over the measure. The ellipsis replaces the limb-by-limb table, reproduced in full at the cited URL. ### Charaka Samhita Vimanasthana 8:117, checked against the source > Next, as regards (examination of the patient by his) dimensions : Instructions are now to be given as regards the dimensions of the body measured by one's fingers. The height, the breadth (including circumference) and length, in their order. tr. Kaviraj Avinash Chandra Kaviratna · https://archive.org/download/BIUSante_47357/BIUSante_47357_djvu.txt Public-domain English for the opening of Vi 8/117. Kaviratna's footnote totals the heights (foot 4, leg 18, knee 4, thigh 18, lower spine 12, back 18, neck 4, head 6) to 84 aṅgulas, three and a half cubits. ### Sushruta Samhita Sutrasthana 35, checked against the source > We shall now give the exact measures of the different limbs and members of the body for the better ascertainment of the duration of life of a patient under investigation. tr. Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122935.html Sushruta frames body measurement explicitly as lifespan prognosis, not as a constitutional descriptor. No verse numbers on the retrieved page. ### Sushruta Samhita Sutrasthana 35, checked against the source > The entire length of a male human body should be a hundred and twenty fingers. tr. Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122935.html A flat contradiction with Charaka Vi 8/117, which gives 84 aṅgulas. Both are in retrieved public-domain texts and neither can be quietly preferred. The clearest example in this term group of why the lexicon records disagreement rather than resolving it. ### Sushruta Samhita Sutrasthana 35, checked against the source > The dimensions of the different limbs and members of the body, laid down above, should be understood as to have been measured by the standard of one's (man's or woman's) own finger's width, and a person, whose limbs and organs are found to correspond to the above-said measures, is sure to live to a good and hearty old age tr. Kaviraj Kunja Lal Bhishagratna · https://www.wisdomlib.org/hinduism/book/sushruta-samhita-volume-1-sutrasthana/d/doc122935.html Confirms the self-referential aṅgula unit in Sushruta and extends it explicitly to women, which matters, because the 84 vs 120 discrepancy is sometimes explained away as a male/female difference and this passage does not support that. ## Not to be confused with - **pramāṇa (epistemology).** The decisive disambiguation, and one WHO documents by carrying both senses. Vimana 8 uses pramāṇa in a third way too, in balapramāṇa at verse 94. - **pramā.** WHO ITA-1.8.2, 'Knowledge: Valid knowledge', the result, where pramāṇa is the means. - **aṅgula.** The unit, not the measurement, and it is the patient's own; two correctly measured patients can differ in absolute centimetres. - **saṃhanana.** Pramāṇa asks whether the parts are the right size; saṃhanana whether they are well put together. - **mātrā.** Also Englished as 'measure', but used for dose and food quantity, never for body proportion. ## Renderings that do not hold - anthropometry. Implies measurement against population norms in fixed units; the classical procedure normalises every patient to his own finger, the opposite methodological move. - height. Vi 8/117 gives utsedha, vistāra and āyāma for each part, not a single stature. - body mass or build. No criterion here concerns mass, and Vi 8/115 immediately before rejects reading strength off body size. - proof or evidence, in a clinical passage. The epistemological sense imported into Vi 8/117 makes nonsense of a passage about finger-widths. ## Open questions Recorded rather than resolved. - Is the 84 vs 120 aṅgula discrepancy discussed by the commentators, and on what grounds is either preferred? - Has anyone tested the lifespan claim attached to correct proportion?
