khara: what the term means and how it is translated

How it is translated, and whether the translation holds

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

Roughness/coarseness

WHO International Standard Terminologies on Ayurveda (2022), entry DG0119 khara · DG0119: 'Roughness/coarseness; one among 20 gurvadi gunas; caused due activated vayu; denotes physiological & pharmacological roughness & harshness; causes depletion.' A separate entry AF1006 khara: 'Rough tongue'. · comparator standard

Comparator. WHO's vāta attribute list also reads 'Rūkṣa (dry), Laghu (light), Śīta (cold), Khara ...'.

keen

Kaviratna, Charaka Samhita, Sutrasthana Lesson I (verse printed as 58 by him; standard 1.59) · archive.org BIUSante_47357 · public-domain translation

'Wind, which may be dry, cold, light, subtile, unstable, clear, keen' renders rūkṣa śīta laghu sūkṣma cala viśada khara; 'keen' for khara is a translator's choice that matches Monier-Williams' 'sharp' sense, not the pharmacological 'rough'.

sharp or pungent

Kaviratna, Charaka Samhita, Sutrasthana Lesson XXVI (his no. 22; standard 26.11) · archive.org BIUSante_47357, printed p. 300 · public-domain translation

'heavy, sharp or pungent, hard, mild, immobile, clear, thick, gross, and possessed of scent' for guru khara kaṭhina manda sthira viśada sāndra sthūla gandha; 'sharp or pungent' for khara is doctrinally odd and collides with kaṭu.

rough (to tactual perception)

Bhishagratna, Sushruta Samhita, Sutrasthana ch. XLVI · wisdomlib doc141678; archive.org in.ernet.dli.2015.43171 printed p. 567 · public-domain translation

'Parchedness is the opposite of oleaginousness; it produces stypsis and makes a thing rough to tactual perception.' Here khara is rendered as an effect of rūkṣa, following the Sanskrit of Su.Su. 46.516. For the twenty-guṇa list proper Bhishagratna renders karkaśa as 'Roughness'.

hard, harsh, rough, sharp, pungent, acid (opposed to mṛdu and ślakṣṇa)

Monier-Williams Sanskrit-English Dictionary (1899), p. 337 · dictionary

Confirms both the 'rough' and 'sharp' senses; the Ayurvedic technical sense fixes on 'rough' as opposite of ślakṣṇa.

स्नेहमार्दवकृत् स्निग्धो बलवर्णकरस्तथा | रूक्षस्तद्विपरीतः स्याद्विशेषात् स्तम्भनः खरः ||५१६||

tr. Sanskrit quoted; English by Bhishagratna · source

In Sushruta's guṇa-karma passage khara appears as a characteristic of rūkṣa, while the second decade of guṇas uses karkaśa (46.521: 'श्लक्ष्णः पिच्छिलवज्ज्ञेयः कर्कशो विशदो यथा'). Bhishagratna: 'Parchedness is the opposite of oleaginousness; it produces stypsis and makes a thing rough to tactual perception.' and 'Humidity is like sliminess. Roughness is like absorption.'

Aṣṭāṅga HṛdayaSutrasthana 1:18 (as printed on easyayurveda.com; verify in a printed edition) · address only, nothing quoted to check

Enumerates the twenty guṇas as ten named qualities 'with their opposites' (ślakṣṇa named, khara implied as its opposite). No public-domain English translation; no quotation recorded.

Not to be confused with

rūkṣa (dry)
Both are vāta attributes and Sushruta 46.516 even lists khara as a property of rūkṣa; but rūkṣa is the opposite of snigdha (unctuous) while khara is the opposite of ślakṣṇa (smooth).
kaṭhina (hard)
Kaviratna's 'sharp... hard' and Monier-Williams' 'hard, harsh' invite confusion; kaṭhina pairs with mṛdu, khara with ślakṣṇa.
tīkṣṇa (sharp/penetrating)
Kaviratna's 'keen' and 'sharp' for khara are the standard English for tīkṣṇa; the pharmacological khara is tactile roughness.
karkaśa
Sushruta's term for the same slot in the twenty-guṇa list (Su.Su. 46.521); treat as synonym in Sushruta, not a 21st guṇa.

Renderings that do not hold

  • sharp / keen / pungent. Kaviratna's renderings at Ca.Su. 1.59 and 26.11; follow the dictionary's secondary sense and collapse khara into tīkṣṇa or kaṭu.
