Matsya Purana — Description of Pralaya: Drying
पौराणं रूपमास्थाय स्वपित्यमितविक्रमः एकार्णवजलव्यापी योगी योगमुपाश्रितः //
paurāṇaṃ rūpamāsthāya svapityamitavikramaḥ ekārṇavajalavyāpī yogī yogamupāśritaḥ //
Assuming his ancient, Purāṇic form, that one of immeasurable prowess remained in yogic repose; pervading the waters of the single cosmic ocean, the Yogi abided, taking refuge in Yoga.
It depicts the Pralaya condition where all is submerged in the single cosmic ocean (ekārṇava), while the Supreme remains all-pervasive and established in yogic absorption rather than being affected by dissolution.
Indirectly, it frames worldly duties as time-bound within cosmic cycles; a king or householder should practice dharma with detachment, remembering that stability and power are transient compared to the Lord’s yogic sovereignty over Pralaya.
No direct Vāstu or ritual rule is stated; the takeaway is cosmological—temples and rites symbolically mirror cosmic order, and this verse highlights the primal 'one-ocean' state that precedes renewed creation.
