Matsya Purana — Genealogy of Kaśyapa: Ādityas
गृध्री गृध्रान्कपोतांश्च पारावतविहंगमान् हंससारसक्रौञ्चांश् च प्लवाञ्छुचिरजीजनत् //
gṛdhrī gṛdhrānkapotāṃśca pārāvatavihaṃgamān haṃsasārasakrauñcāṃś ca plavāñchucirajījanat //
Then the creative power brought forth Gṛdhrī and the vultures, pigeons and doves (and other birds), along with swans, cranes, and krauñca-birds, and also the plava-birds—pure in their kind—into existence.
This verse pertains to sṛṣṭi (creation), specifically the generation of bird species; it does not describe pralaya, but it supports the Purāṇic idea of an ordered, category-wise emergence of life.
Indirectly, it grounds dharma in a world of diverse living beings—implying protection of creatures and restraint from needless harm, themes that later inform royal and household ethics in Purāṇic teaching.
No direct Vāstu or ritual rule appears here; the verse is a cosmological catalogue, useful mainly for contextual reading of Matsya Purana’s creation framework rather than temple-architecture prescriptions.
