keen

Charaka Samhita tr. A. C. Kaviratna, public domain · Su.1 his 59 (pitta 'hot, keen'); Su.26 his 24 (agneya 'hot, keen'); Su.26 saline taste 'It is keen'; Su.26 his 20 eight energies 'mild and keen'; footnote to Su.22 his 10: ''Tikshna' is pungent' · public-domain translation

Mostly 'keen', but 'pungent' in the Su.22 langhana list, where 'pungent' elsewhere means kaṭu rasa; a real ambiguity in his usage.

keen

Sushruta Samhita tr. K. L. Bhishagratna, public domain, via wisdomlib · Su.40 ('mild or keen' among eight potencies); Su.41 (taijasa 'pungent and keen'; 'keenness of a drug from the fact of its producing pain in the mouth'; apya 'devoid of keenness') · public-domain translation

Consistent 'keen/keenness'.

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.

Charaka SamhitaSutrasthana 1:Standard 1.60; Kaviratna prints 59 · checked against the source

Bile, which may be cold, hot, keen, soft, sour, liquid, and bitter, is speedily cured by objects having adverse attributes.

WARNING: Kaviratna's 'cold ... soft ... bitter' do not correspond to the Sanskrit (sasneha, sara, kaṭu); only 'hot, keen, sour, liquid' are sound. Use for the rendering of tīkṣṇa only.

Some say that mild and keen, heavy and light, oily and dry, and hot and cooling, are the eight kinds of Energy which objects may have. Others are of opinion that objects have only two kinds of Energy, viz., cooling and hot.

tr. A. C. Kaviratna · source

Tīkṣṇa as one of the eight vīryas (Kaviratna's 'Energy'). Sanskrit as retrieved: मृदुतीक्ष्णगुरुलघुस्निग्धरूक्षोष्णशीतलम्| वीर्यमष्टविधं केचित्, केचिद्द्विविधमास्थिताः||६४|| (https://www.carakasamhitaonline.com/index.php/Atreyabhadrakapyiya_Adhyaya).

Sushruta SamhitaSutrasthana 41:Suśruta Sūtrasthāna 40.5 — 'केचिदष्टविधमाहुः — शीतमुष्णं स्निग्धं रूक्षं विशदं पिच्छिलं मृदु तीक्ष्णं ... एतानि खलु वीर्याणि स्वबलगुणोत्कर्षाद्रसमभिभूयात्मकर्म कुर्वन्ति ... तदेतन्निदर्शनमात्रमुक्तम् ॥५॥' (Trikamji/Dalhaṇa ed. 1938, pp. 175-176). This closes the Su.40 half of the openQuestion 'Sanskrit verse numbers for Sushruta Su.40-41 eight-virya passages'; the Su.41 half was already at 41.11. · checked against the source

तत्र य इमे गुणा वीर्यसंज्ञकाः शीतोष्णस्निग्धरूक्षमृदुतीक्ष्णपिच्छिलविशदास्तेषां तीक्ष्णोष्णावाग्नेयौ, शीतपिच्छिलौ अम्बुगुणभूयिष्ठौ, पृथिव्यम्बुगुणभूयिष्ठः स्नेहः, तोयाकाशगुणभूयिष्ठं मृदुत्वं, वायुगुणभूयिष्ठं रौक्ष्यं, क्षितिसमीरणगुणभूयिष्ठं वैशद्यं; विपाकाद्गुरुलघुगुणौ ॥११॥ — Suśruta Sū. 41.11, mūla as printed in the Dalhaṇa edition (Trikamji, Pandurang Jawaji 1938), p. 183. Variant recorded there: 'गुरुलघुमृदुतीक्ष्णा' (Hāraṇacandra).

tr. K. L. Bhishagratna · source

A variant reading placing guru (with laghu, displacing picchila and viśada) in Suśruta's eight-vīrya list at Su.Su. 41.11 is attested: Jadavji Trikamji's apparatus to Dalhaṇa's edition records it as Hāraṇacandra's pāṭha, both in the list itself (fn. 2) and in the dosha-action clause of the same sūtra (fn. 6). Dalhaṇa's own gloss supports the printed list without guru. Bhishagratna's 'heavy' is therefore consistent with an attested variant tradition and should not be recorded as an error, though his exact eight-item sequence reproduces neither the printed text nor that variant. Separately, the Su.40 eight-vīrya passage is Su.Su. 40.5.

Not to be confused with

manda
Opposite member (Kaviratna's note 'Tikshna in Manda'; WHO 'opposite to dullness').
kaṭu (pungent rasa)
A taste, not a guna; Kaviratna's 'pungent' for tīkṣṇa in Su.22 collides with his 'pungent' for kaṭu.
uṣṇa
Hot; co-listed with tīkṣṇa in fire-dominant lists and in Pitta, but a separate pair (uṣṇa/śīta).
khara
Rough; Kaviratna renders khara 'keen' (Su.1.59) and 'sharp' (Su.26.11, Wind list), so his 'sharp/keen' is not always tīkṣṇa.
tīkṣṇāgni
A state of digestive fire (WHO AF2265), not the drug guna.
tīkṣṇa vīrya (degree)
WHO DG0351 uses it as 'higher potency', a grading of strength rather than the sharpness quality.

Renderings that do not hold

  • pungent. Kaviratna's Su.22 choice; 'pungent' is the standard English for kaṭu rasa, so it conflates a taste with a guna.
  • spicy / hot (in the culinary sense). Tīkṣṇa is speed and penetration of action; the texts pair it with manda (slow), not with cold.

Open questions

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

  • Sanskrit verse numbers for Sushruta Su.40-41 eight-vīrya passages.
  • Whether Chakrapani's gloss on tīkṣṇa supports WHO's 'quick penetration'.
