Matsya Purana — Description of Pralaya: Drying
तं वरेण्यं परमेष्ठी हृषीकेशमुपाश्रितः ततो भगवतस्तस्य रश्मिभिः परिवारितः //
taṃ vareṇyaṃ parameṣṭhī hṛṣīkeśamupāśritaḥ tato bhagavatastasya raśmibhiḥ parivāritaḥ //
Then Paramēṣṭhī (Brahmā), taking refuge in that most excellent Hṛṣīkeśa (Lord Viṣṇu), stood surrounded by the radiance streaming from that Blessed Lord.
It presents a key Purāṇic theological principle: even the cosmic creator (Brahmā/Paramēṣṭhī) relies on Viṣṇu as the ultimate refuge, implying Viṣṇu’s supremacy across cycles of creation and dissolution.
By modeling śaraṇāgati (taking refuge in the highest good), it implies that rulers and householders should ground their actions in devotion, humility, and dependence on dharma rather than ego or mere power.
No direct Vāstu or temple-rule detail appears; the verse is primarily theological, emphasizing divine radiance and refuge—ideas often invoked ritually in praise (stuti) and consecratory contexts.
