Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
ततस्तूर्णं हृषीकेशस् तमृक्षपतिमञ्जसा जाम्बवन्तं स जग्राह क्रोधसंरक्तलोचनः //
tatastūrṇaṃ hṛṣīkeśas tamṛkṣapatimañjasā jāmbavantaṃ sa jagrāha krodhasaṃraktalocanaḥ //
Then, swiftly, Hṛṣīkeśa seized Jāmbavān—the lord of bears—at once, his eyes reddened with anger.
This verse does not discuss Pralaya; it depicts an immediate action in a narrative conflict where Hṛṣīkeśa forcefully seizes Jāmbavān.
Indirectly, it reflects the kṣatriya-like duty of decisive protection and confronting disorder: prompt action against obstruction is portrayed as part of upholding order (dharma), though the verse itself is a combat moment rather than a legal-ethical injunction.
No Vāstu, temple-building, iconography, or ritual procedure is stated in this verse; it is purely narrative, emphasizing speed, force, and the emotional intensity of the encounter.
