मनु-उपदेशः — भूत-उत्पत्ति, इन्द्रिय-निवृत्ति, तथा पर-स्वभाव-विवेकः
Manu’s Instruction on Elemental Origination, Sense-Withdrawal, and Discrimination of the Supreme Nature
मलिनाः: प्राप्तुयु: शुद्धि यथा पूर्णा नदीं नरा: । अवगाहा सुविद्धांसो विद्धि ज्ञानमिदं तथा
malināḥ prāptuyuḥ śuddhiṃ yathā pūrṇāṃ nadīṃ narāḥ | avagāhā suvidvāṃso viddhi jñānam idaṃ tathā ||
毗湿摩说：正如身躯污秽之人，入水充盈的大河沐浴便得清净；同样应当明白：沉浸于这知识之河，即使心念染垢者，也能得以净化，并具足真实的明悟。

Educational Q&A
Knowledge functions like a purifying river: sincere immersion in true understanding cleanses inner defilements (mental impurity) and leads to clarity and wisdom, supporting righteous conduct.
In the Shanti Parva’s instruction to Yudhishthira, Bhishma uses a vivid analogy—bathing in a full river—to explain how engagement with liberating knowledge purifies a person and makes them truly learned.
