Matsya Purana — Inquiry into Taraka’s Slaying and the Prelude to Guha
ततस्ते ब्रह्मणो ऽभ्याशं जग्मुर्भयनिपीडिताः भीतांश्च त्रिदशान्दृष्ट्वा ब्रह्मा तेषामुवाच ह //
tataste brahmaṇo 'bhyāśaṃ jagmurbhayanipīḍitāḥ bhītāṃśca tridaśāndṛṣṭvā brahmā teṣāmuvāca ha //
Then, tormented by fear, they went near Brahmā. Seeing those thirty gods frightened, Brahmā spoke to them.
It does not describe Pralaya directly; it shows a cosmic crisis-response pattern where the Devas seek Brahmā’s counsel—an administrative/cosmic order motif that often frames larger creation-destruction cycles in Purāṇic narration.
By analogy, it models dharmic conduct in danger: when overwhelmed, one should seek guidance from a legitimate authority (guru/elder/king or scripture) rather than act from panic—an ethical principle consistent with Purāṇic rajadharma and gṛhastha discipline.
No Vāstu or ritual procedure is stated in this verse; its significance is narrative—establishing that Brahmā is the refuge and decision-point before subsequent instructions, which in other contexts can include rites, vows, or prescribed actions.
