Matsya Purana — The Greatness and Procedure of the Aṅgāra
भित्त्वा स सप्त पातालान् अदहत्सप्त सागरान् अनेकवक्त्रनयनो ज्वलज्ज्वलनभीषणः //
bhittvā sa sapta pātālān adahatsapta sāgarān anekavaktranayano jvalajjvalanabhīṣaṇaḥ //
Breaking through the seven netherworlds, he scorched the seven oceans—many-faced and many-eyed, dreadful with blazing fire.
It depicts a pralaya-like destructive surge: a blazing being breaks through the seven Pātālas and scorches the seven oceans, emphasizing the Purāṇic idea that dissolution can overwhelm all cosmic layers—below and above.
Indirectly, it reinforces impermanence: since even oceans and netherworlds are vulnerable in cosmic cycles, kings and householders are urged elsewhere in the Matsya Purana to uphold dharma, charity, and restraint rather than pride in temporary power or possessions.
No direct Vāstu or ritual procedure is stated; the takeaway is cosmological—temples and rites in other chapters are framed as dharmic supports within an impermanent world subject to pralaya.
