Matsya Purana — Mahāgaurī’s Entry
ददृशे तं च देवेशो हुताशं शुकरूपिणम् तमुवाच महादेवः किंचित्कोपसमन्वितः //
dadṛśe taṃ ca deveśo hutāśaṃ śukarūpiṇam tamuvāca mahādevaḥ kiṃcitkopasamanvitaḥ //
Then the Lord of gods beheld Hutāśa (Agni) in the form of a boar; and Mahādeva addressed him, his words edged with a slight anger.
This verse does not describe Pralaya directly; it frames a narrative moment where Śiva confronts Agni, using vivid deity-iconography (Agni taking a boar-form) rather than cosmological dissolution.
Indirectly, it underscores the Purāṇic ethic that even powerful forces (like Agni, central to household sacrifice) remain accountable to higher divine order—supporting the householder’s disciplined, rule-bound approach to ritual and conduct.
The key ritual signal is the epithet Hutāśa (Agni), the sacrificial fire who ‘consumes offerings’; the verse situates Agni in a mythic episode, reinforcing Agni’s centrality to yajña and consecratory rites (though no Vāstu rule is stated in this line).
