रणभूमिवर्णनम् — Devāsuropama-yuddha and the ‘River’ Metaphor of the Battlefield
माद्रीपुत्रो तु शकुनिमुलूकं च महारथम्
mādrīputro tu śakunim ulūkaṃ ca mahāratham
Sañjaya said: Madri’s son (Nakula) then confronted Śakuni, and also Ulūka, that great chariot-warrior—pressing the battle against the chief instigators and champions of the Kaurava side.
संजय उवाच
The verse highlights kṣatriya-dharma in action: confronting those seen as principal agents of wrongdoing (Śakuni and his son) within the lawful arena of battle, where accountability is pursued through sanctioned combat rather than private vengeance.
In Sañjaya’s battlefield report, Nakula (son of Mādrī) advances against Śakuni and also Ulūka, described as a mahāratha, indicating a focused engagement with prominent Kaurava figures during the Kurukṣetra war.
