Adhyāya 214: Tapas Redefined—Perpetual Discipline, Hospitality, and the Ethics of Eating (तपः-निरूपणम्, विघसाशी-अतिथिप्रिय-धर्मः)
दश विद्याद् धमन्यो<त्र पज्चेन्द्रियगुणावहा: । याभि: सूक्ष्मा: प्रतायन्ते धमन्यो5न्या: सहस्रश:
daśa vidyād dhamanyo 'tra pañcendriyaguṇāvahāḥ | yābhiḥ sūkṣmāḥ pratāyante dhamanyo 'nyāḥ sahasraśaḥ ||
Bhīṣma said: In this body one should understand that there are ten principal channels (dhamanīs) which carry the qualities of the five senses—sound and the rest—enabling sensory apprehension. Along with these, thousands of other subtle channels spread throughout the entire body. The teaching situates the human organism as an ordered field of functions, where disciplined understanding of the body supports ethical self-governance and steadiness of mind.

Educational Q&A
The verse teaches a structured view of the body: ten principal channels convey the sensory qualities, while innumerable subtle channels pervade the body. Such knowledge supports self-mastery—understanding how perception arises helps one regulate desire, restraint, and ethical conduct.
In the Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and allied disciplines. Here he shifts into an explanatory, quasi-physiological account of the body’s internal channels and their role in sensory experience, as part of a broader teaching on self-knowledge and control.
