Sāttvika-vṛtta-kathana (Brahmā on the Conduct of Sattva) — Chapter 38
मुधा ज्ञानं मुधा वृत्तं मुधा सेवा मुधा श्रम: । एवं यो युक्तधर्म: स्यात् सोअमुत्रात्यन्तमश्षुते,नाना प्रकारकी सांसारिक जानकारी, सकाम व्यवहार, सेवा और श्रम व्यर्थ है--ऐसा समझकर जो कल्याणके साधनमें लग जाता है, वह परलोकमें अक्षय सुखका भागी होता है
mudhā jñānaṁ mudhā vṛttaṁ mudhā sevā mudhā śramaḥ | evaṁ yo yukta-dharmaḥ syāt so 'mutrātyantam aśnute ||
Vāyu said: “Worldly learning is futile; worldly conduct is futile; service and toil pursued for merely temporal ends are futile.” One who, understanding this, becomes devoted to the true means of welfare (dharma rightly applied) attains imperishable, unsurpassed happiness in the world beyond.
