निद्रान्धास्ते महाराज परिश्रान्ताश्न संयुगे
nidrāndhās te mahārāja pariśrāntāś ca saṃyuge
Sañjaya said: O great king, they were as though blinded by sleep, utterly exhausted amid the battle—overcome by fatigue in the very press of war.
संजय उवाच
Even the mightiest warriors are bound by human limits: exhaustion and loss of alertness can cloud judgment in war, reminding us that ethical discernment (dharma-buddhi) is fragile when the body and mind are overstrained.
Sañjaya reports to King Dhṛtarāṣṭra that the fighters were so worn out in the ongoing conflict that they appeared 'sleep-blinded'—a vivid description of battlefield fatigue affecting their awareness and effectiveness.
