मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
रूप॑ चक्षुस्तथा पाकस्त्रिविधं तेज उच्यते । रस: क्लेदश्न जिह्दा च त्रयो जलगुणा: स्मृता:
rūpaṃ cakṣus tathā pākaḥ trividhaṃ teja ucyate | rasaḥ kledaś ca jihvā ca trayo jalaguṇāḥ smṛtāḥ ||
रूप, नेत्र और परिपाक (पाचन)—ये तीन तेज के कार्य कहे गए हैं। रस, क्लेद (गीलापन) और जिह्वा—ये तीन जल के गुण माने गए हैं।

The verse teaches an elemental analysis of experience: certain sensory and bodily functions are traced to the principles of fire (form/visibility, sight, digestion) and water (taste, moisture, tongue). This supports ethical self-discipline by encouraging discernment (viveka) about the body’s processes rather than identification with them.
In Śānti Parva, Bhīṣma continues his post-war instruction to Yudhiṣṭhira, offering philosophical classification of the body and senses. Here he enumerates the three functions associated with tejas and the three associated with water as part of a broader teaching on nature, embodiment, and right understanding.
