Janaka–Parāśara: Varṇa, Gotra, and Dharma Inquiry
इन्द्रियाणि नरे पठच षष्ठं तु मन उच्यते । सप्तमीं बुद्धिमेवाहु: क्षेत्रज्ञ: पुनरष्टम:,मानव-शरीरमें पाँच ज्ञानेन्द्रियाँ और छठा मन बताया जाता है। बुद्धिको सातवीं और क्षेत्रञको आठवाँ कहते हैं
indriyāṇi nare pañca ṣaṣṭhaṃ tu mana ucyate | saptamīṃ buddhim evāhuḥ kṣetrajñaḥ punar aṣṭamaḥ ||
毗湿摩阐明人的内在构成：有五种感官机能，而意（manas）被称为第六。理智（buddhi）称为第七；而“田地之知者”（kṣetrajña）——那觉知的自我，作为见证者观照身体及其作用——被宣示为第八。其伦理旨趣在于：当分辨自我与知觉、决断之器具，使人得以统御诸根，以坚定与明辨而行。
भीष्म उवाच
Educational Q&A
A human being is analyzed into instruments (five senses, mind, intellect) and the true subject (kṣetrajña, the witnessing Self). Ethical mastery begins by recognizing that the Self is distinct from sensory impulses and mental fluctuations, enabling disciplined, discerning action.
In the Shanti Parva’s instruction to Yudhishthira, Bhishma continues a philosophical-ethical exposition, classifying the components of the person to support teachings on self-control, right understanding, and the pursuit of peace and liberation after the war.
