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 ||
ພີດສະມະ ອະທິບາຍວ່າ: «ຮູບ (ສິ່ງທີ່ເຫັນໄດ້), ຕາ, ແລະການຍ່ອຍ/ການປຸງແຕ່ງໃນກາຍ—ສາມຢ່າງນີ້ເປັນກິດຂອງໄຟ (tejas). ສ່ວນນ້ຳ ກໍມີສາມ: ລົດຊາດ, ລີ້ນ, ແລະຄວາມຊຸ່ມຊື່ນ (ຄວາມເປັນນ້ຳ)».
भीष्म उवाच
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.
