Matsya Purana — Origins of Gods and Beings: Daksha’s Progeny
शिवा मनोजवं पुत्रम् अविज्ञातगतिं तथा अवाप चानलात् पुत्राव् अग्निप्रायगुणौ पुनः //
śivā manojavaṃ putram avijñātagatiṃ tathā avāpa cānalāt putrāv agniprāyaguṇau punaḥ //
Śivā bore a son named Manojava, and also another named Avijñātagati. Again, from Anala she obtained two sons whose qualities were largely like those of fire.
This verse does not describe Pralaya directly; it reflects the Matsya Purana’s creation-era genealogical mapping, where beings and their offspring embody elemental traits (here, fire-like qualities).
Indirectly, it supports the Purana’s broader framework that dharma is taught within an ordered cosmos of lineages; kingship and household duty are later grounded in these origin narratives and hereditary transmissions of qualities (guṇas).
No explicit Vāstu or ritual procedure is stated; however, the emphasis on Agni-like qualities resonates with later ritual theology where fire (Agni) is central to yajña and consecration rites discussed elsewhere in the Matsya Purana.
