Adhyāya 214: Tapas Redefined—Perpetual Discipline, Hospitality, and the Ethics of Eating (तपः-निरूपणम्, विघसाशी-अतिथिप्रिय-धर्मः)
वातपित्तकफाद् रक्त त्वड्मांसं स्नायुमस्थि च । मज्जां देहं शिराजालैस्तर्पयन्ति रसा नृणाम्
vāta-pitta-kaphād raktaṁ tvag-māṁsaṁ snāyum asthi ca | majjāṁ dehaṁ śirā-jālaiḥ tarpayanti rasā nṛṇām ||
毗湿摩阐明：由饮食所成的滋养精华“罗娑”(rasa)，入身之后，经由诸脉络之网流行，滋养人的三种体液——风（vāta）、胆（pitta）、痰（kapha）——并及血、皮、肉、筋、骨、髓，从而维系并强健全身。此教诲指出：节制而有序的滋养，是人生与法（dharma）中安定之基。

Educational Q&A
Food, when properly digested, becomes rasa—the nourishing essence—which circulates through bodily channels and sustains all tissues and humors. Ethical living (dharma) is supported by bodily steadiness, so disciplined nourishment is presented as a practical foundation for self-control and right conduct.
In Bhishma’s instruction during the Shanti Parva, he describes how nourishment works within the body: the essence of food spreads through a network of vessels and strengthens the humors and bodily constituents, thereby sustaining the whole person.
