vyāna vāta: what the term means and how it is translated
vyāna vāta व्यानः is an Ayurvedic technical term. It is rendered into English in 3 different ways across 5 sources, 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.

Circulating vata
WHO International Standard Terminologies on Ayurveda · Term ID ITA-2.1.1.4 · terminology standard
WHO's description: 'Subtype of vata seated in the cardiac region (hrdaya), which circulates or diffuses through the body. It performs the function of circulating of fluids through heart to all parts of the body, as well as transporting various materials from one body part to another.' Follows Ashtanga Hridaya Su.12.6 (hṛdi sthitaḥ) rather than Sushruta, which gives vyāna no seat. Note WHO's description is entirely about transport and omits the motor functions (flexion, extension, blinking) that Charaka Ci.28.9 makes central. Lemma is bare vyānaḥ.

the Vyana (left untranslated); 'courses (acts) through the whole organism ... sending the lymph chyle, etc. all through the body'
Sushruta Samhita, tr. Kaviraj Kunja Lal Bhishagratna (public domain) · Nidanasthana ch. 1, Bhishagratna's section 10 · public-domain translation
'Lymph chyle' is Bhishagratna's rendering of rasa, a period equivalence that no modern source would accept but which is what the public-domain text actually says.
Vyana — one of the 'five airs or breaths'; 'the fifth is that which pervades the whole body and moves in various directions, transverse and otherwise'
Charaka Samhita, tr. Avinash Chandra Kaviratna (public domain) · Sutrasthana, translator's footnote · public-domain translation
Kaviratna's footnote gloss. Consistent with Charaka Ci.28.9's kṛtsna-deha-cārī, though it is his own note rather than a translation of Charaka's definition.

The source's rendering runs to a full definition and is not reproduced here, because this project has not cleared that source for quotation.
'All involuntary actions' is an autonomic-nervous-system framing with no classical counterpart. Charaka Ci.28.9's list (gati, prasāraṇa, ākṣepa, nimeṣa) mixes voluntary locomotion with reflex blinking, so the voluntary/involuntary axis is not the text's own.

Follows Sushruta's pañcadhā ceṣṭayati. Bhishagratna's footnote [5] enumerates the same five as 'expansion, flexion, lowering down and lifting up or lateral thrusting of any part of the body'.
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 SamhitaNidanasthana 1 (Vatavyadhi Nidana):Bhishagratna's section 10 = Sanskrit 1.17b-18 · checked against the source
The Vayu known as the Vyana courses (acts) through the whole organism, and its functions consist in sending the lymph chyle, etc. all through the body and in helping the out-flow of blood (Asrik) and perspiration. Five kinds of muscular movements are ascribed to the action of the Vyana Vayu, a deranged condition of which is generally attended with diseases which are not confined to any particular region, member, or organ of the body, but are found to affect the whole organism (such as, fever, etc). 10.
Sushruta gives vyāna NO seat, only whole-body range, and three function groups: conveyance of rasa, outflow of blood and sweat, and five kinds of bodily movement. Corresponding Sanskrit, cross-checked at a separate URL: 'कृत्स्नदेहचरो व्यानो रससंवहनोद्यतः ||१७|| स्वेदासृक्स्रावणश्चापि पञ्चधा चेष्टयत्यपि | क्रुद्धश्च कुरुते रोगान् प्रायशः सर्वदेहगान् ||१८||'. Bhishagratna's footnote [5] specifies the five movements as 'expansion, flexion, lowering down and lifting up or lateral thrusting of any part of the body'.
Sushruta SamhitaNidanasthana 1 (Vatavyadhi Nidana):Bhishagratna's sections 11-12 = Sanskrit 1.19-20 · checked against the source
An aggravated condition of both the Vyana and Apana Vayus may produce Prameha and disorders of the seminal fluid, while a simultaneous excitement of the five vital Vayus leads to a sure and speedy termination of life.
A rare classical statement of a COMBINED subtype pathology (vyāna + apāna together producing prameha and śukra disorders), and of the prognosis when all five are simultaneously deranged. Corresponding Sanskrit: 'शुक्रदोषप्रमेहास्तु व्यानापानप्रकोपजाः ||२०||'.
Charaka SamhitaChikitsasthana 28 (Vatavyadhi Chikitsa):28.9 · checked against the source
देहं व्याप्नोति सर्वं तु व्यानः शीघ्रगतिर्नृणाम् | गतिप्रसारणाक्षेपनिमेषादिक्रियः सदा ||९||
Charaka's vyāna pervades the whole body and is śīghragati (swift-moving); its functions are gati (locomotion), prasāraṇa (extension), ākṣepa (flexion/throwing), nimeṣa (closing of the eyelids) and the like. Charaka's vyāna is therefore primarily a MOTOR subtype, not a circulatory one, the circulatory emphasis in WHO and in modern writing comes from Sushruta's rasasaṃvahana and from Vagbhata's hṛdi sthitaḥ.
Charaka SamhitaSutrasthana Lesson XII (Vatakalakaliya) in Kaviratna's numbering:Kaviratna's section 6 · checked against the source
It exists in the fivefold form of Prana, Udana, Samana, Vyana, and Apana.
Names vyāna as one of the five in a lawfully quotable English Charaka. No seat or function given.
Ashtanga HridayaSutrasthana 12 (Doshabhediya):12.6b-7 · address only, nothing quoted to check
Vagbhata seats vyāna in the HEART (vyāno hṛdi sthitaḥ), has it range the entire body with great velocity (kṛtsnadehacārī mahājavaḥ), and at 12.7 assigns it gati, apakṣepaṇa (downward movement), utkṣepa (upward movement), nimeṣa and unmeṣa (closing and opening of the eyelids), adding that 'nearly all the activities of embodied beings are bound up in it'. Vagbhata's hṛdi sthitaḥ is the source of WHO's 'seated in the cardiac region'. Sanskrit mūla and verse numbering verified on the retrieved page; not quoted, as Ashtanga Hridaya has no public-domain English translation.
Sharngadhara SamhitaPurva Khanda 5 (Kaladikakhyana):5.27-28 · address only, nothing quoted to check
Sharngadhara's seat list at 5.27 ends with sarvāṅgadeśeṣu (all parts of the body), which the naming verse 5.28 maps to vyāna. Consistent with Charaka and Sushruta on range; unlike Vagbhata, Sharngadhara does not seat vyāna in the heart. Sanskrit mūla verified on the retrieved page; not quoted, as Sharngadhara has no public-domain English translation.
Not to be confused with
- rasa and rakta (the circulating substances)
- Vyāna is the mover, not the thing moved. Sushruta Ni.1.17b has it 'rasasaṃvahanodyata', engaged in conveying rasa. Modern writing routinely slides from 'vyāna circulates the blood' to 'vyāna IS the circulation', which erases the doṣa/dhātu distinction.
- vyāna vāyu of yoga
- The yogic vyāna is the pervasive current linking the other four and is often tied to coordination and to the nāḍī network. The Ayurvedic vyāna is defined by Charaka Ci.28.9 through specific motor acts (locomotion, extension, flexion, blinking), not through a subtle-body network.
- prāṇa vāta
- Vagbhata seats vyāna in the heart (AH Su.12.6) while WHO's prāṇa entry says prāṇa controls 'the intellect, heart, sensory and motor organs'. Both end up at the heart. Charaka keeps them apart cleanly: prāṇa is above the diaphragm and ingestive; vyāna is everywhere and motor.
- udāna vāta
- A citation hazard rather than a conceptual one: in Ashtanga Hridaya, verse 12.6 contains the END of udāna's function list and the BEGINNING of vyāna's definition. A bare 'AH Su.12.6' citation can be read as supporting either. Check the hemistich.
- vyāna in the context of svedavaha srotas
- Both Sushruta (svedāsṛksrāvaṇa) and Charaka's samāna verse (svedavaha srotas) involve sweat. Sushruta assigns the OUTFLOW of sweat to vyāna; Charaka Ci.28.8 seats samāna in the sweat-carrying channels. Sweat is contested between the two subtypes across the two texts.
Renderings that do not hold
- the circulatory system / blood circulation. WHO's 'Circulating vata' invites it, but Charaka Ci.28.9 makes vyāna's functions motor (gati, prasāraṇa, ākṣepa, nimeṣa) with no mention of circulation at all. The circulatory reading rests on Sushruta and Vagbhata only. Rendering vyāna as 'circulation' silently picks a side in a textual disagreement.
- the Motor-Sensory Nerves. From Bhishagratna's 1911 footnote [3]. Worse, that footnote is internally corrupt: it assigns 'the energy of the Motor-Sensory Nerves' to UDANA, naming Udana twice and omitting Vyana entirely. Anyone quoting that footnote for vyāna is quoting a printing error, and anyone quoting it for udāna is quoting a colonial neuroanatomical equation. I inspected the footnote text directly and it reads exactly this way on the retrieved page.
- the autonomic nervous system / all involuntary actions. As on the Kerala Tourism page. Charaka's function list includes both voluntary locomotion and reflex blinking, so the voluntary/involuntary distinction is not the one the text is drawing.
- lymph chyle. Bhishagratna's rendering of rasa. Accurate to 1911 physiology, misleading now, rasa is the first dhātu, not lymph or chyle. Quote it as his wording, never as a modern equivalence.
- blood pressure. Follows from the hypertension literature (PMID 29153383) treating vyāna vāta as the operative factor in blood pressure. That paper proposes the link; it does not establish it, and no classical locus mentions anything answering to blood pressure.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Does Chakrapani read rasa circulation into Charaka Ci.28.9, or does Charaka genuinely omit it and confine vyāna to motor function?
- Which text first seats vyāna in the heart, is Ashtanga Hridaya Su.12.6 the earliest, given that Sushruta, Charaka and Sharngadhara all give it whole-body range instead?
- Is Bhishagratna's footnote [3] corrupt in the 1911 printing itself, or only in the wisdomlib transcription? A physical copy would settle it.
- Does NAMASTE assign vyāna vāta a code, and does its English term follow WHO's 'Circulating vata'?
