Matsya Purana — The Pushkara Manifestation
विश्वान्देवान्देवमाता विश्वेशाजनयत् सुतान् मरुत्वती मरुत्वतो देवानजनयत्सुतान् //
viśvāndevāndevamātā viśveśājanayat sutān marutvatī marutvato devānajanayatsutān //
Devamātā (the Mother of the gods) bore the sons known as the Viśvedevas; and Marutvatī gave birth to the divine Maruts as her sons.
This verse is a creation/genealogy statement (sarga): it lists divine progenitors and their offspring (Viśvedevas and Maruts), not a pralaya event.
Indirectly, it supports the Purāṇic model of lineage and ordered generation—used elsewhere in the Matsya Purāṇa to ground dharma in cosmic and ancestral continuity, though this verse itself is purely genealogical.
No direct Vāstu/temple rule is stated here; the ritual takeaway is that Viśvedevas and Maruts are recognized divine classes often invoked in Vedic-Purāṇic rites, so the verse helps identify their mythic origin.
