Adhyāya 2: Nārada’s Disclosure—Karṇa’s Training and the Brahmin’s Curse (Śānti-parva)
स तत्रेष्वस्त्रमकरोद् भगुश्रेष्ठाद् यथाविधि । प्रियश्चाभवदत्यर्थ देवदानवरक्षसाम्
sa tatreṣv astram akarod bhaguśreṣṭhād yathāvidhi | priyaś cābhavad atyartha devadānavarakṣasām ||
அங்கே அவன் ப்ருகு குலத்தில் சிறந்தவரிடமிருந்து முறையோடு திவ்யாஸ்திரத்தைப் பெற்றான்; அதன் பின் தேவர்கள், தானவர்கள், ராட்சசர்கள் அனைவருக்கும் அவன் மிகுந்த பிரியமானவனானான்।
नारद उवाच
Power (astra-knowledge) is to be gained and used only through proper discipline and prescribed procedure (yathāvidhi). Such rule-bound conduct fosters trust and esteem even across hostile communities, implying that ethical method matters as much as capability.
Nārada narrates that the person in question, while staying there, duly obtained/learned a missile-weapon from a foremost Bhṛgu sage. As a result, he became highly favored among three major groups—gods, Dānavas, and Rākṣasas—highlighting his broad acceptance and influence.
