Adhyāya 214: Tapas Redefined—Perpetual Discipline, Hospitality, and the Ethics of Eating (तपः-निरूपणम्, विघसाशी-अतिथिप्रिय-धर्मः)
तस्मात् तदभिघाताय कर्म कुर्यादकल्मषम् | रजस्तमश्न हित्वेह यथेष्टां गतिमाप्रुयात्
tasmāt tad-abhighātāya karma kuryād akalmaṣam | rajas-tamaś ca hitveha yatheṣṭāṁ gatim āpnuyāt ||
Bhīṣma dit : Ainsi, pour frapper (et vaincre) cet esprit indocile, il faut accomplir une action sans tache—sans faute ni désir égoïste. En agissant ainsi ici-bas, en abandonnant rajas et tamas, on atteint la voie de progrès que l’on recherche véritablement.
भीष्म उवाच
To master the mind, one should engage in blameless, desireless action (akalmaṣa karma). Such disciplined action weakens passion (rajas) and inertia/delusion (tamas), enabling the seeker to attain the intended spiritual course or goal (gati).
In Shanti Parva, Bhishma instructs Yudhishthira on dharma and inner discipline. Here he explains a practical method for subduing the mind: perform pure, untainted action so that the lower guṇas are relinquished and higher progress becomes possible.
