Shloka 15
मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
पुरुषैरिन्द्रियाणीह वेदितव्यानि कृत्स्नश: । तमो रजश्न सत्त्वं च तेडपि भावास्तदाश्रिता:
puruṣair indriyāṇīha veditavyāni kṛtsnaśaḥ | tamo rajaś ca sattvaṃ ca te 'pi bhāvās tad-āśritāḥ ||
毗湿摩说道：“在此世间，人应当彻底明了并谨慎守护自己的诸根（以及引导它们的内在机能）。因为三德——惰性（tamas）、激动（rajas）与清明（sattva）——正是依托这些器具而起作用。”

Educational Q&A
One should vigilantly know and regulate the senses and inner faculties, because the three guṇas (sattva, rajas, tamas) express themselves through them; mastery of conduct begins with mastery of these instruments.
In the Śānti Parva’s instruction section, Bhīṣma is advising Yudhiṣṭhira on ethical and psychological discipline, emphasizing sense-awareness and governance as the basis for stable character and right action.
