Matsya Purana — Description of Pralaya: Drying
भस्मीकृत्य ततः सर्वांल् लोकांल्लोकगुरुर्हरिः भूयो निर्वापयामास युगान्तेन च कर्मणा //
bhasmīkṛtya tataḥ sarvāṃl lokāṃllokagururhariḥ bhūyo nirvāpayāmāsa yugāntena ca karmaṇā //
Having then reduced all the worlds to ashes, Hari—the Teacher of the worlds—again caused them to be quenched and stilled, by the act that belongs to the end of an age (yuga).
It depicts pralaya as a twofold cosmic process: the worlds are first burned to ash and then “quenched” into stillness—an ordered, yuga-end operation governed by Hari.
By presenting Hari as lokaguru who regulates destruction and restoration, it implies that rulers and householders should act with measured restraint—ending harmful actions and restoring order (dharma) rather than acting from chaos or excess.
No direct Vastu or temple-rule detail appears; the ritual takeaway is symbolic—“quelling” after “burning” mirrors purification followed by pacification (śānti), a common sequence in expiatory and concluding rites.
