Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
तं दृष्ट्वा तु महाशब्दं स चक्रे ऋक्षराड्बली शब्दं श्रुत्वा तु गोविन्दः खड्गपाणिः प्रविश्य सः अपश्यज्जाम्बवन्तं तम् ऋक्षराजं महाबलम् //
taṃ dṛṣṭvā tu mahāśabdaṃ sa cakre ṛkṣarāḍbalī śabdaṃ śrutvā tu govindaḥ khaḍgapāṇiḥ praviśya saḥ apaśyajjāmbavantaṃ tam ṛkṣarājaṃ mahābalam //
Seeing him, the mighty king of bears (Ṛkṣarāja) let out a tremendous roar. Hearing that sound, Govinda entered with sword in hand, and beheld Jāmbavān—the powerful lord of the bears.
This verse is not about pralaya; it is a heroic narrative moment emphasizing recognition through sound (a great roar) and the meeting with Jāmbavān, rather than cosmology or dissolution.
Indirectly, it highlights readiness and protective vigilance: Govinda responds immediately to a perceived threat (the roar) and enters armed, reflecting the kṣatriya-like ethic of prompt action in safeguarding order.
No explicit Vāstu/temple-architecture or ritual procedure is stated in this verse; it functions primarily as narrative description of an encounter and identification of key figures.
