Karṇa-parva Adhyāya 20 — Yudhiṣṭhira–Duryodhana Encounter and Escalation of Arms
सर्वमाख्यातवान् वीरो वासुदेव: किरीटिने
sarvam ākhyātavān vīro vāsudevaḥ kirīṭine | śrutvā ca tad bhayān ghoraṃ mahad bhrātari vartamānam | pāṇḍukumāro 'rjuno 'bravīd—hṛṣīkeśa! śīghram etān aśvān vardhaya ||
Sañjaya said: The heroic Vāsudeva (Kṛṣṇa) told everything to Arjuna, the wearer of the diadem. Hearing it, and seeing the dreadful, great peril that had befallen his brother, Arjuna, son of Pāṇḍu, said: “Hṛṣīkeśa, quickly urge these horses on.”
संजय उवाच
The verse highlights kṣatriya-duty expressed as swift, decisive action in response to imminent danger to one’s kin, and the coordinated reliance between warrior and charioteer—Arjuna’s resolve paired with Kṛṣṇa’s guidance and execution.
After Kṛṣṇa (Vāsudeva) has explained the situation to Arjuna, Arjuna perceives a grave threat to his brother on the battlefield and urgently instructs Kṛṣṇa, addressed as Hṛṣīkeśa, to drive the chariot faster by urging the horses onward.
