Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
जघान शक्रो वज्रेण सर्वान्धर्मबहिष्कृतान् नहुषस्य प्रवक्ष्यामि पुत्रान्सप्तैव धार्मिकान् //
jaghāna śakro vajreṇa sarvāndharmabahiṣkṛtān nahuṣasya pravakṣyāmi putrānsaptaiva dhārmikān //
Śakra (Indra) struck down with his thunderbolt (vajra) all those who had been cast out from dharma. Now I shall recount Nahusha’s seven sons, all of them righteous.
This verse is not about pralaya; it belongs to a dynastic narrative, stressing moral order (dharma) upheld by divine authority (Indra) rather than cosmic dissolution.
It frames dharma as the standard for legitimacy: those who abandon righteousness are ‘excluded from dharma’ and meet downfall, while Nahusha’s lineage is introduced as dhārmika—implying that rulers and householders must uphold ethical conduct to preserve social order and honor.
No Vāstu, temple-building, or ritual procedure is mentioned in this verse; its focus is ethical-genealogical, contrasting the unrighteous with Nahusha’s righteous sons.
