Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
तथा खरो मृदू रूक्षो लघुर्गुरुतरोडपि च | एवं द्वादशधा स्पर्शों वायव्यो गुण उच्यते,उष्ण, शीत, सुख, दुःख, स्निग्ध, विशद, खर, मृदु, रूक्ष, हलका, भारी और अधिक भारी--इस प्रकार वायु-सम्बन्धी स्पर्श गुणके बारह भेद कहे जाते हैं
tathā kharo mṛdu rūkṣo laghur gurutaro 'pi ca | evaṃ dvādaśadhā sparśo vāyavyo guṇa ucyate ||
Bharadvāja berkata: “Demikian juga, sentuhan dihuraikan sebagai dua belas lipatan berhubung dengan unsur angin (Vāyu): kasar dan lembut; kering; ringan dan berat (bahkan teramat berat); dan begitu juga panas dan sejuk, nikmat dan sakit, licin berminyak dan jernih. Maka demikianlah dinyatakan dua belas sifat sentuhan yang terkait dengan Vāyu.”
भरद्वाज उवाच
The verse classifies tactile experience (sparśa) as a set of distinct qualities and states that, in this teaching context, these are specifically attributed to the air principle (vāyavya guṇa). It presents a systematic, analytical way of understanding sensation by enumerating its modes.
In the didactic discourse of Śānti Parva, Bharadvāja is explaining a philosophical taxonomy of qualities. Here he continues an enumeration, stating that touch connected with Vāyu is described as twelvefold, listing representative tactile opposites such as rough/soft, light/heavy, and related experiential pairs.
