Nārāyaṇāstra-utpātaḥ — Aśvatthāman’s Rallying Roar after Droṇa’s Fall (द्रोणपर्व, अध्याय १६७)
अर्जुन च युधां श्रेष्ठ प्राद्रवन्तं महारथम् । अलम्बुषो महाराज राक्षसेन्द्रो न्यवारयत्
arjunaṃ ca yudhāṃ śreṣṭhaṃ prādravantaṃ mahāratham | alambuṣo mahārāja rākṣasendro nyavārayat ||
Sañjaya said: O King, as Arjuna—the foremost among warriors—charged forward in his great chariot, Alambuṣa, the lord of the Rākṣasas, checked and obstructed him. In the press of battle, even the most righteous and capable hero could be strategically delayed, his resolve tested amid the turmoil.
