Mind as Charioteer; Kṣetrajña, Tapas, and Dhyāna-Yoga
Adhyātma-Upadeśa
ज्ञानं निःश्रेय इत्याहुर्वद्धा निश्चितदर्शिन:
jñānaṃ niḥśreya ity āhur baddhā niścita-darśinaḥ
বায়ু বললেন—যাঁদের দৃষ্টি স্থির ও নিশ্চিত, সেই জ্ঞানী বৃদ্ধগণ বলেন: সত্য জ্ঞানই নৈঃশ্রেয়স—পরম কল্যাণ ও মুক্তির পথ।
वायुदेव उवाच
The verse asserts that jñāna (true knowledge) is niḥśreyas—the supreme good—because it leads beyond temporary gains to ultimate welfare, i.e., liberation-oriented fulfillment.
Vāyudeva is speaking in a didactic context, presenting a concise doctrinal claim attributed to established seers: that the highest aim is attained through knowledge rather than through merely external achievements.
