Matsya Purana — The Pushkara Manifestation
भवं च प्रभवं चैव हीशं चासुरहं तथा अरुणं चारुणिं चैव विश्वावसुबलध्रुवौ //
bhavaṃ ca prabhavaṃ caiva hīśaṃ cāsurahaṃ tathā aruṇaṃ cāruṇiṃ caiva viśvāvasubaladhruvau //
“(They are) Bhava and Prabhava; Hīśa and also Asuraha; Aruṇa and Aruṇi as well; and Viśvāvasu, Bala, and Dhruva.”
This verse is a catalogue of names of celestial/divine beings; it does not directly describe pralaya, but it supports the Purana’s cosmological mapping of beings that populate the created order.
Indirectly: such enumerations are used for correct recitation, remembrance, and ritual literacy; a king/householder is encouraged to preserve sacred knowledge, sponsor recitations, and maintain continuity of dharmic tradition.
The verse itself gives no Vāstu rule; its ritual value lies in accurate name-recitation (nāma-smaraṇa) within Purāṇic reading traditions and potentially in invoking specific classes of beings in broader ritual contexts.
