तेषामस्त्राणि सर्वेषामुत्तमास्त्रविदां वर:
teṣām astrāṇi sarveṣām uttamāstravidāṁ varaḥ
ಅವರಲ್ಲೆಲ್ಲಾ ಅವನೇ ಉತ್ಕೃಷ್ಟ ಅಸ್ತ್ರವಿದ್ಯೆಯನ್ನು ತಿಳಿದವರಲ್ಲಿ ಶ್ರೇಷ್ಠನು; ಅವರ ಪ್ರಯುಕ್ತ ಅಸ್ತ್ರಗಳೂ ಆ ನೈಪುಣ್ಯದಿಂದ ಅತ್ಯಂತ ಭಯಂಕರವಾಗಿದ್ದವು.
संजय उवाच
The verse highlights that mastery over powerful weapons (astra-vidyā) makes one exceptionally formidable, implying an ethical burden: the greater the power and knowledge, the greater the responsibility in how it is used in war.
Sañjaya, narrating the battle events, characterizes a warrior as the foremost among weapon-knowers, emphasizing the terrifying effectiveness of the weapons being deployed in the Drona Parva conflict.
