Matsya Purana — The Syamantaka Jewel Episode and the Vrishni–Sainya Genealogies
अथ दीर्घेण कालेन मृगयां निर्गतः पुनः यदृच्छया च गोविन्दो बिलस्याभ्याशमागमत् //
atha dīrgheṇa kālena mṛgayāṃ nirgataḥ punaḥ yadṛcchayā ca govindo bilasyābhyāśamāgamat //
Then, after a long time, he again set out for the hunt; and by sheer chance Govinda came near the mouth of a cave.
This verse does not speak directly about Pralaya; it sets a narrative scene where a chance movement (“yadṛcchayā”) leads to a consequential encounter, a common Purāṇic device before major revelations.
By mentioning mṛgayā (the hunt), the verse touches a classic dharma theme: royal pursuits can become turning points for ethical instruction—later verses typically clarify whether the hunt is restrained, purposeful, or a cause of distraction.
No Vāstu or ritual rule is stated here; the only spatial marker is “bila” (cave), which functions as a narrative setting rather than a prescription for temple-building or rites.
