Śiva’s Battlefield Manifestation and Vyāsa’s Śatarudrīya Exposition (शिवप्रादुर्भावः शतरुद्रीयव्याख्यानम्)
तद् बल॑ भरतश्रेष्ठ वध्यमानं तदा निशि
tad balaṁ bharataśreṣṭha vadhyamānaṁ tadā niśi
तद् बलं भरतश्रेष्ठ वध्यमानं तदा निशि, क्षीयमाणं समरे दारुणं समपद्यत।
संजय उवाच
The verse underscores the moral strain of warfare when violence continues under cover of night: even in a kṣatriya conflict governed by norms, chaos and darkness can blur restraint, raising questions of dharma and accountability.
Sañjaya reports to Dhṛtarāṣṭra that a certain army/force is being slaughtered at night, setting a grim scene of nocturnal fighting and the resulting devastation.
