Matsya Purana — Intermediate Dissolution
और्वानलो ऽपि विकृतिं गमिष्यति युगक्षये विषाग्निश्चापि पातालात् संकर्षणमुखच्युतः भवस्यापि ललाटोत्थस् तृतीयनयनानलः //
aurvānalo 'pi vikṛtiṃ gamiṣyati yugakṣaye viṣāgniścāpi pātālāt saṃkarṣaṇamukhacyutaḥ bhavasyāpi lalāṭotthas tṛtīyanayanānalaḥ //
At the end of the age, even the Aurva fire will undergo a fearful transformation. And the poisonous fire too, released from Pātāla from the mouth of Saṅkarṣaṇa; as well as the fire of Bhava (Śiva) that springs from his forehead—the blaze of the third eye.
It lists specific cosmic fires that manifest at yuga-kṣaya—Aurvānala, a poisonous/netherworld fire linked to Saṅkarṣaṇa, and Śiva’s third-eye blaze—indicating dissolution through overwhelming heat and destructive energy.
Indirectly, it frames impermanence: kings and householders should pursue dharma, charity, and right conduct knowing worldly power and possessions end in pralaya; the verse functions as a warning against complacency and attachment.
No direct Vāstu or temple rule is stated; ritually, the verse underscores the supremacy of cosmic fire in dissolution, supporting Purāṇic emphasis on fire-offerings (homa) and purification as symbolic counterpoints to destructive yugānta heat.
