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 · https://archive.org/details/dli.ministry.30779 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. - Sanskrit verse numbers for Sushruta Su.40-41 eight-vīrya passages. - Whether Chakrapani's gloss on tīkṣṇa supports WHO's 'quick penetration'. ## Citation Age Ayurveda Nighantu, "tīkṣṇa", https://nighantu.ageayurveda.com/lexicon/tikshna/, CC BY 4.0.
