Shloka 27
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 ||
毗湿摩说道：是故，为击破并降伏那桀骜之心，当行无垢之业——无过失、无私欲。于此世如是行，舍离罗阇斯与塔摩斯，便得所求之进趣之道。

Educational Q&A
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.
