Matsya Purana — Vishnu’s Battle with Mathana
स तैर्बाणैरभिहतो महिषो ऽचलसंनिभः परिवर्तितकायो ऽधः पपात न ममार च //
sa tairbāṇairabhihato mahiṣo 'calasaṃnibhaḥ parivartitakāyo 'dhaḥ papāta na mamāra ca //
Struck by those arrows, the buffalo—vast as a mountain—rolled over and fell down; yet he did not die.
This verse does not address Pralaya; it is a combat-description verse emphasizing the opponent’s immense size and surprising survival despite being struck by arrows.
Indirectly, it reflects the Purāṇic ideal of courage and perseverance in conflict—qualities expected of a ruler or protector—though no explicit rājadharma or gṛhastha-duty instruction appears in this line.
None is stated here; the vocabulary is martial (bāṇa, falling, not dying) rather than Vāstu, temple-building, or ritual procedure.
