Matsya Purana — Description of Pralaya: Drying
संशोषमात्मना कृत्वा समुद्रानपि देहिनः दग्ध्वा संप्लाव्य च तथा स्वपित्येकः सनातनः //
saṃśoṣamātmanā kṛtvā samudrānapi dehinaḥ dagdhvā saṃplāvya ca tathā svapityekaḥ sanātanaḥ //
Having, by his own power, dried up even the oceans, and then burning the embodied beings and again inundating (the worlds), the One Eternal Being alone lies down in cosmic sleep.
It outlines pralaya as a sequence of desiccation (even the oceans), burning of embodied life, and a final inundation, after which the Eternal One (Vishnu/Narayana) rests in cosmic sleep (yoganidra) before renewal.
By stressing the inevitability of dissolution for all embodied beings, it supports the Matsya Purana’s ethical thrust: rulers and householders should govern and live with detachment, perform dharma and charity, and prioritize enduring spiritual merit over temporary worldly security.
No direct Vastu or temple-building rule is stated; ritually, the verse functions as a pralaya contemplation that underlines the need for lasting religious acts (yajña, dāna, vrata) rather than reliance on impermanent material constructions.
