Matsya Purana — Characteristics of Dvāpara and Kali Yugas
तथा रजस्तमो भूयः प्रवृत्ते द्वापरे पुनः आद्ये कृते नाधर्मो ऽस्ति स त्रेतायां प्रवर्तितः //
tathā rajastamo bhūyaḥ pravṛtte dvāpare punaḥ ādye kṛte nādharmo 'sti sa tretāyāṃ pravartitaḥ //
Likewise, in the Dvāpara Yuga, rajas and tamas become predominant again. In the first age, the Kṛta (Satya) Yuga, there is no adharma; it begins to manifest in the Tretā Yuga.

It does not describe Pralaya directly; it explains cyclical moral decline across the Yugas, showing how the guṇas (rajas and tamas) rise and enable adharma to appear as time progresses.
By linking adharma to the dominance of rajas-tamas in later ages, it implies that kings and householders must consciously uphold dharma—through self-restraint, justice, and sattvic conduct—because the age itself tends toward disorder.
No direct Vāstu or ritual rule is stated; indirectly, it supports the Purāṇic idea that rites, discipline, and dharmic institutions become increasingly necessary in later Yugas to counter rising rajas and tamas.
