Matsya Purana — Agastya’s Origin
यस्मादस्मद्द्विषामेष शरणं वरुणालयः तस्माद्भवद्भ्यामद्यैव क्षयमेष प्रणीयताम् //
yasmādasmaddviṣāmeṣa śaraṇaṃ varuṇālayaḥ tasmādbhavadbhyāmadyaiva kṣayameṣa praṇīyatām //
Since this one—an enemy of ours—has taken refuge in Varuṇa’s abode (the ocean), therefore let him be led by you both, this very day, to his destruction.
It does not describe cosmic pralaya directly; it uses Varuṇa’s abode (the ocean) as a mythic locus of refuge, showing the ocean’s sacred-juridical role rather than dissolution imagery.
It reflects rājadharma in practice: identifying a hostile wrongdoer and ordering decisive action. The verse frames punishment as an executed directive, emphasizing timely enforcement rather than mere intention.
No Vāstu or temple-ritual rule appears explicitly; the only ritual-cosmological marker is “Varuṇa’s abode,” a standard Purāṇic sacred geography term for the sea.
