Matsya Purana — Omens in Tripura and the Nārada–Maya Dialogue on Dharma
ईश्वरस्वरघोषेण नर्दमाने महावृषे जयत्सु विप्रेषु तथा गर्जत्सु तुरगेषु च //
īśvarasvaraghoṣeṇa nardamāne mahāvṛṣe jayatsu vipreṣu tathā garjatsu turageṣu ca //
As the great bull roared aloud with a lordly, thunder-like cry, the brahmins raised shouts of victory, and the horses too neighed and bellowed.
This verse does not discuss pralaya; it depicts an auspicious, energetic scene of royal or martial acclamation—roaring proclamation, victory-cries, and the loud neighing of horses.
By portraying brahmins proclaiming victory and a “great bull” (ideal hero/king) sounding forth, it reflects the Purāṇic ideal of kingship upheld by priestly blessing and public acclaim—suggesting righteous rule and valor supported by dharmic voices.
No Vāstu or temple-building rule is stated; the ritual note is the presence of brahmins voicing “jaya” (victory), a common auspicious acclamation in royal ceremonies and martial processions.
