Adhyāya 214: Tapas Redefined—Perpetual Discipline, Hospitality, and the Ethics of Eating (तपः-निरूपणम्, विघसाशी-अतिथिप्रिय-धर्मः)
वाक्सम्भाषाप्रवृत्तं यत् तन्मन:परिवर्जितम् | बुद्धया चाध्यवसीयीत ब्रह्म॒चर्यमकल्मषम्
vāksambhāṣāpravṛttaṃ yat tan manaḥparivarjitam | buddhyā cādhyavasīyīta brahmacaryam akalmaṣam ||
毗湿摩说道：“凡仅由言语与交谈所推动、而心念却弃之不顾的行为，都应以清明的理解而坚定决断。人当以智慧立誓，守持无垢的梵行（brahmacarya，自制与清净之行）。”

Educational Q&A
True ethical discipline must be grounded in inner intention, not merely in outward speech. One should use discernment (buddhi) to make a firm resolve toward pure brahmacarya—self-restraint free from moral taint.
In Śānti Parva, Bhīṣma instructs Yudhiṣṭhira on dharma and right conduct. Here he emphasizes that vows and moral practices should not remain superficial or verbal; they must be inwardly accepted and firmly determined, especially regarding brahmacarya.
