vyakti: what the term means and how it is translated

vyakti व्यक्ति is an Ayurvedic technical term. It is rendered into English in 4 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds

Each rendering is given with the source that uses it. The assessment is ours.

Stage of clinical manifestation of a disease

WHO International Standard Terminologies on Ayurveda · ITA-4.6.11 (vyaktiḥ), ch. 4, printed p. 114 · who-ista

WHO description, verbatim: 'The fifth stage of disease manifestation, when a disease or condition becomes clinically manifest.' Re-read from the PDF. WHO adds 'clinical', which is not in the Sanskrit but is the intended sense.

the symptoms which they respectively exhibit in connection with the incidental disease ( Vyakti )

Sushruta Samhita, tr. Kaviraj Kunja Lal Bhishagratna (1907) · Sutrasthana ch. XXI, summary verse · public-domain-translation

Bhishagratna again paraphrases rather than giving a term. In the prose for the stage itself he writes 'the full development or manifestation of a disease' and 'the complete development of the characteristic symptoms'.

Vyakta or Vyakteebhava – Stage of manifestation of disease

easyayurveda.com (Dr Raghuram Y.S. / Dr J.V. Hebbar) · https://www.easyayurveda.com/2016/06/13/shat-kriya-kala-stage-wise-disease-management/ · practitioner-reference

String-matched on the retrieved page. Note this source does not use 'vyakti' at all for the stage, it uses vyakta / vyaktībhāva, and lists 'Vyakta' in its own contents list of the six. The naming of the fifth stage is genuinely unsettled between sources.

siva.sh (machine-generated English layer) · https://www.siva.sh/sushruta-samhita/sutra-sthana/21/36 · machine-translation

LOW AUTHORITY. The same site's Hindi layer for this verse renders व्यक्तिं as 'व्यक्तित्व' (personality), a documented machine-translation failure of exactly the kind this record warns about.

The classical passages

Each citation gives its address so a reader can check it in a printed edition, our account of what the passage establishes, and the result of reading it against its source.

Sushruta SamhitaSutrasthana 21:34 · checked against the source

अत ऊर्ध्वं व्याधेर्दर्शनं वक्ष्यामः- शोफार्बुदग्रन्थिविद्रधिविसर्पप्रभृतीनां प्रव्यक्तलक्षणता ज्वरातीसारप्रभृतीनां च । तत्र पञ्चमः क्रियाकालः ॥३४॥

Sanskrit mūla · source

Critical lexicographic point, re-confirmed: the prose of the fifth stage does NOT use the word vyakti. It says vyādher darśanam (the appearing of the disease) and pravyaktalakṣaṇatā (the state of having fully manifest signs). The name 'vyakti' for this stage comes only from the summary verse 21.36.

Sushruta SamhitaSutrasthana 21:34 · checked against the source

Now we shall deal with the full development or manifestation of a disease. The full manifestation of a disease, such as a swelling, tumour, aneurism (Granthi), Vidradhi (abscess) and erysipelas ( Visarpa ) etc., fever or dysentery, signifies the complete development of the characteristic symptoms, which should be regarded as the fifth occasion for medical treatment.

tr. Kaviraj Kunja Lal Bhishagratna (1907) · source

Bhishagratna's English for the fifth stage, and his 1907 disease equivalents (Granthi as 'aneurism', Visarpa as 'erysipelas') which should be treated as period glosses, not as identifications.

Sushruta SamhitaSutrasthana 21:36 · checked against the source

व्यक्तिं भेदं च यो वेत्ति दोषाणां स भवेद्भिषक् ॥३६॥

Sanskrit mūla · source

The only place in the retrieved verses where the stage is named vyakti. Grammatically vyaktiṃ... doṣāṇām, the manifestation OF THE DOSHAS, which is a subtly different claim from 'manifestation of the disease' used by WHO and by textbooks.

Not to be confused with

rūpa / lakṣaṇa / liṅga: These name the signs and symptoms themselves. WHO ITA-4.5.5 groups the sign-and-symptom synonyms under one entry, noting that 'Ayurveda uses several terms as synonyms for signs and symptoms, based on the different perspectives under which they are understood'. Vyakti names the stage at which those signs are fully present. A symptom is not a stage.
pūrvarūpa: Prodromes belong to the previous stage (sthānasaṃśraya). The vyakti/pūrvarūpa boundary is the diagnostic boundary between 'about to have' and 'has' the disease.
vyakta (Samkhya): In Samkhya philosophy, which Charaka's Sharirasthana engages with at length, vyakta means the manifest as opposed to avyakta, the unmanifest prakriti. Unrelated to pathology, and a live source of confusion in translated Samhita passages.
vyakti in ordinary Sanskrit and modern Hindi: व्यक्ति in current Hindi standardly means 'a person, an individual'. This is the single most dangerous false friend in the whole kriyakala set, and it is not hypothetical: an AI translation layer on a Sanskrit text site rendered व्यक्तिं in this very verse as व्यक्तित्व, personality.
vyakta-avasthā / vyaktībhāva: Alternative names used for the same stage by practitioner sources. If a source names the stage vyakta rather than vyakti, that is a naming difference, not a different stage.

Renderings that do not hold

'individual' / 'personality' / 'individual variation'. Reads the ordinary-language sense of vyakti into a technical staging term. Observed in the wild in a machine-generated Hindi layer on a Sanskrit text site, and it makes the verse say something about constitutional individuality that the text does not say.
'diagnosis'. Conflates the patient's state with the clinician's act. The disease manifests at vyakti whether or not anyone diagnoses it.
'acute phase'. Imports an acute/chronic axis the text does not use. Sushruta explicitly includes long-running conditions such as jvara and atisara in the later stages, and 21.35 makes long duration a feature of the SIXTH stage, not a contrast with the fifth.

Open questions

Recorded rather than resolved. Each one is something this entry cannot currently settle.

Whether commentators (Dalhana) justify naming the fifth stage vyakti when the prose uses vyādher darśanam and pravyaktalakṣaṇatā.
Which of vyakti / vyakta / vyaktībhāva is the dominant form in current BAMS curricula, WHO uses vyakti, a major practitioner reference uses vyakta/vyaktībhāva.
Whether NAMASTE or ICD-11 TM2 carry this term, both lookups failed again; see the shat-kriyakala record.
