Adhyāya 290: Kuntī’s Mantra-Parīkṣā and the Appearance of Sūrya (कुन्ती–सूर्यसंवादः)
तमचिन्त्य प्रहारं स बलवान् वालिन: सुत:
tam acintya prahāraṃ sa balavān vālināḥ sutaḥ
Mārkaṇḍeya said: The mighty son of Vāli, having pondered that unimaginable blow, steadied himself—recognizing the weight of the strike and the peril it foretold.
मार्कण्डेय उवाच
The verse highlights that real power includes discernment: when confronted with an extraordinary threat, a hero must first comprehend its seriousness and respond with steadiness rather than impulsiveness.
Markandeya describes a pivotal instant in which Vāli’s powerful son registers an inconceivable strike (prahāra) and prepares himself in response, indicating a sudden escalation in the encounter.
