Matsya Purana — Yayati’s Fall from Heaven and the Greatness of the Righteous
सन्तः प्रतिष्ठा हि सुखच्युतानां सतां सदैवामरराजकल्प ते संगताः स्थावरजङ्गमेशाः प्रतिष्ठितस्त्वं सदृशेषु सत्सु //
santaḥ pratiṣṭhā hi sukhacyutānāṃ satāṃ sadaivāmararājakalpa te saṃgatāḥ sthāvarajaṅgameśāḥ pratiṣṭhitastvaṃ sadṛśeṣu satsu //
The virtuous are indeed the firm refuge and support of those who have fallen away from happiness, for the good are ever like the king of the gods. When the lords of the immovable and the moving beings (sthāvara and jaṅgama) enter such noble company, they become established; and you too are established among saints who are your equals in virtue.
It does not describe Pralaya directly; instead, it emphasizes moral order: even when happiness is lost, stability is regained through association with the virtuous, implying dharma as the sustaining principle across cosmic change.
It teaches that a ruler or householder who has slipped from prosperity should seek the counsel and company of the righteous; sat-saṅga functions as a practical dharmic remedy that re-establishes authority, reputation, and well-being.
No Vastu or ritual procedure is specified; the key takeaway is preparatory—purity of association (sat-saṅga) is presented as a foundational principle that supports successful rites and orderly governance.
