Matsya Purana — Intermediate Dissolution
देवतानां प्रतिष्ठादि यच्चान्यद्विद्यते भुवि तत्सर्वं विस्तरेण त्वं धर्मं व्याख्यातुमर्हसि //
devatānāṃ pratiṣṭhādi yaccānyadvidyate bhuvi tatsarvaṃ vistareṇa tvaṃ dharmaṃ vyākhyātumarhasi //
You ought to explain, in detail, the whole of Dharma—beginning with the consecration (installation) of the deities and whatever else is found upon the earth.
This verse does not directly describe Pralaya; it sets the agenda for a comprehensive teaching on Dharma, explicitly including deity consecration (pratiṣṭhā) and other worldly regulations.
By requesting a detailed exposition of Dharma, Manu frames the king/householder’s duty as grounded in correct ritual and ethical order—especially maintaining public religion through proper consecrations and allied rites that uphold social and cosmic stability.
The key term is pratiṣṭhā—formal installation/consecration of deities—central to temple ritual completion and closely tied to Vastu and iconography practices that the Matsya Purana later systematizes.
