Adhyāya 48: Brahmopadeśa on Prāṇāyāma, Sāttvika Vṛtti, and the Sattva–Kṣetrajña Question
पृथग्भूतं ततः सत्त्वमित्येतदविचारितम् | पृथग्भावश्न विज्ञेय: सहजश्नापि तत्त्वतः
pṛthagbhūtaṃ tataḥ sattvam ity etad avicāritam | pṛthagbhāvaś ca vijñeyaḥ sahajaś cāpi tattvataḥ ||
বায়ু বললেন— তাঁদের মতে ক্ষেত্রজ্ঞ থেকে সত্ত্ব পৃথক; এবং এ কথা যথাযথ বিচার না করেই স্বতঃসিদ্ধ ধরা হয়। কিন্তু বুঝতে হবে— স্বভাবত একসঙ্গে অবস্থান করলেও তত্ত্বত তারা পৃথক।
वायुदेव उवाच
The verse urges discernment: even if sattva (a guṇa or constituent of prakṛti) appears closely associated with the conscious knower (kṣetrajña), one should understand their essential difference—consciousness is the witness, while sattva is a quality of nature.
Vāyudeva is presenting a philosophical clarification within the Ashvamedhika Parva’s instructional discourse, critiquing an unexamined claim and directing the listener to a more precise understanding of the relation between the self (kṣetrajña) and the guṇas such as sattva.
