Adhyāya 16: Saṃśaptaka-vrata and the Diversion of Arjuna (द्रोणपर्व, अध्याय १६)
युधिष्ठिरं स विद्ध्वा तु शरै: संनतपर्वभि: । युगन्धरं तु भल्लेन रथनीडादपातयत्,तब झुकी हुई गाँठवाले बाणोंद्वारा युधिष्ठिरको घायल करके द्रोणाचार्यने एक भल्ल नामक बाणद्धारा मारकर युगन्धरको रथकी बैठकसे नीचे गिरा दिया
yudhiṣṭhiraṃ sa viddhvā tu śaraiḥ sannatapārva-bhiḥ | yugandharaṃ tu bhallena rathanīḍād apātayat ||
Sañjaya said: Having struck Yudhiṣṭhira with arrows whose joints were bent, Droṇācārya wounded him; then, with a bhalla arrow, he felled Yugandhara from the chariot-seat.
संजय उवाच
The verse highlights the harsh impartiality of war: even the most dharmic ruler can be wounded, and battlefield duty is executed through skill and resolve. It reflects kṣatriya-dharma—action performed amid conflict, where outcomes hinge on prowess and circumstance rather than moral status alone.
Droṇa first wounds Yudhiṣṭhira with specialized arrows described as having bent joints, then uses a bhalla arrow to strike down Yugandhara, causing him to fall from the chariot-seat.
