Nara-Nārāyaṇa–Nārada Discourse on Vision, Elements, and Entry into Vāsudeva
रुजन्ति हि शरीराणि रोगा: शारीरमानसा: । सायका इव तीक्ष्णाग्रा: प्रयुक्ता दृढ्धन्विभि:,शारीरिक और मानसिक रोग सुदृढ़ धनुष धारण करनेवाले वीर पुरुषोंके छोड़े हुए तीक्ष्ण बाणोंके समान शरीरको पीड़ा देते हैं
rujanti hi śarīrāṇi rogāḥ śārīra-mānasāḥ | sāyakā iva tīkṣṇāgrāḥ prayuktā dṛḍha-dhanvibhiḥ ||
那罗陀说道：身病与心病确实折磨众生之身，如同强弓勇士所放之利箭，锋芒锐利，穿刺不息。
नारद उवाच
Educational Q&A
Suffering arises not only from external enemies but also from internal causes—physical and mental disorders—which can wound as sharply as weapons. Therefore one should cultivate disciplined living, mental steadiness, and prudent care of body and mind as part of dharma.
Nārada is speaking in the Śānti Parva, using a battlefield simile: diseases (both bodily and mental) are compared to keen arrows shot by strong bowmen, emphasizing the intensity and inevitability of such afflictions when they arise.
