Shloka 29
मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
भारत! इस प्रकार मैंने तुम्हारे समक्ष बुद्धिकी सम्पूर्ण गतिका विशद विवेचन किया है। बुद्धिमान पुरुषको चाहिये कि वह अपनी सम्पूर्ण इन्द्रियोंको काबूमें रखे ।।
bhārata! evaṃ mayā tava samakṣaṃ buddheḥ samagrā gatiḥ spaṣṭīkṛtā. buddhimān puruṣaḥ sarvendriyāṇi vaśe kuryāt. sattvaṃ rajas tamaś caiva prāṇināṃ saṃśritāḥ sadā. trividhā vedanā caiva sarvasattveṣu dṛśyate.
婆罗多啊，如此我已在你面前清晰陈述了理智（buddhi）运行的全程与作用。智者当摄持一切诸根，使之受制。因为在一切有情之中，萨埵、罗阇、怛摩三德（guṇa）恒常依止；因此在诸众生身上，皆可见与之相应的三类感受与苦恼。

Educational Q&A
Bhīṣma teaches that wisdom requires mastery over the senses, because all beings are conditioned by the three guṇas—sattva, rajas, and tamas—which generate differing kinds of experience and suffering; restraint and discernment help one rise above their compulsions.
In the Śānti Parva dialogue, Bhīṣma continues instructing Yudhiṣṭhira on inner discipline and the workings of the mind/intellect, concluding a prior explanation of buddhi and turning to the universal presence of the three guṇas and their effects on lived experience.
