नित्यं यज्ञोपवीती स्याच्छुक्लवासा: शुचिव्रत: । नियतो यमदानाभ्यां सदा शिष्टैश्न संविशेत्,सदा यज्ञोपवीत धारण किये रहे, स्वच्छ वस्त्र पहने, उत्तम व्रतका पालन करे, शौच- संतोष आदि नियमों और सत्य-अहिंसा आदि यमोंके पालनपूर्वक यथाशक्ति दान करता रहे तथा सदा शिष्ट पुरुषोंके साथ निवास करे
nityaṁ yajñopavītī syāc chuklavāsāḥ śucivrataḥ | niyato yamadānābhyāṁ sadā śiṣṭaiś na saṁviśet |
風神ヴァーユは言った。「人はつねに聖紐（ヤジュニョーパヴィータ）を身につけ、清らかな白衣をまとい、浄く規律ある誓戒を守れ。ヤマ（倫理的抑制）を修し、力に応じて施しを行うことで自らを律し、つねに教養と善行を備えた人々と交わり、粗野な者の中に住むな。」
वायुदेव उवाच
Educational Q&A
The verse teaches a dharmic lifestyle: maintain outward and inward purity (sacred thread, clean clothing, pure vows), cultivate self-restraint through yama (moral disciplines), practice charity according to ability, and seek the company of the virtuous while avoiding corrupting associations.
Vāyudeva is giving prescriptive guidance on right conduct—laying down practical markers of disciplined living and ethical formation, emphasizing that character is strengthened by restraint, generosity, and association with śiṣṭa (cultured, righteous) people.
