Matsya Purana — Secondary Creation: Appointment of Cosmic Regents and Consecration of Directi...
विष्णुं रवीणामधिपं वसूनाम् अग्निं च लोकाधिपतिश्चकार प्रजापतीनामधिपं च दक्षं चकार शक्रं मरुतामधीशम् //
viṣṇuṃ ravīṇāmadhipaṃ vasūnām agniṃ ca lokādhipatiścakāra prajāpatīnāmadhipaṃ ca dakṣaṃ cakāra śakraṃ marutāmadhīśam //
He appointed Viṣṇu as lord over the Ādityas (solar deities) and the Vasus; he made Agni the lord of the worlds; he made Dakṣa the chief of the Prajāpatis; and he appointed Śakra (Indra) as ruler of the Maruts.
It reflects the post-creation ordering of the cosmos: divine functions are assigned to specific deities, showing how the universe is administered after creation rather than describing dissolution.
By portraying a structured distribution of authority (each deity with a defined jurisdiction), it implicitly supports the dharmic principle that rulers and householders should assign roles, uphold order, and govern according to proper offices and responsibilities.
No direct Vāstu or temple-building rule is stated; the ritual takeaway is the prominence of Agni and other deities as functional powers—useful for understanding why specific gods receive offerings in rites aligned with their cosmic domains.
