Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
विस्मृताभिनयं सर्वं यत्पुरा भरतोदितम् शशाप भरतः क्रोधाद् वियोगादस्य भूतले //
vismṛtābhinayaṃ sarvaṃ yatpurā bharatoditam śaśāpa bharataḥ krodhād viyogādasya bhūtale //
When all the acting (abhinaya) that Bharata had formerly taught was forgotten, Bharata—angered by this separation—pronounced a curse upon him on the earth.
This verse does not discuss pralaya; it focuses on a moral-narrative consequence (a curse) arising from forgotten teaching and separation.
It implies a dharmic caution: negligence toward learned instruction and allowing anger born of separation to govern one’s actions leads to harmful consequences—an ethical lesson applicable to rulers and householders alike.
No Vastu, temple-building, or ritual procedure is stated; the technical term here is abhinaya (performative expression), pointing instead to the discipline of tradition-preservation.
