Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
जगुर्हर्षसमाविष्टा ननृतुश्चासुराङ्गनाः ततो महोत्सवो जातो दानवानां द्विजोत्तमाः //
jagurharṣasamāviṣṭā nanṛtuścāsurāṅganāḥ tato mahotsavo jāto dānavānāṃ dvijottamāḥ //
Overcome with delight, the women of the Asuras sang and danced; thus, O best of the twice-born, a great festival arose among the Dānavas.
This verse does not describe Pralaya; it depicts a worldly scene of rejoicing—Asura women singing and dancing—indicating a festive moment among the Dānavas rather than cosmic dissolution.
Indirectly, it functions as a narrative contrast: Purāṇas often show that pleasure, celebration, and social spectacle can arise even among unrighteous groups, reminding kings/householders to govern and live by dharma rather than being led solely by revelry.
No Vāstu or temple-ritual rule is stated explicitly; the only ritual implication is the notion of a “mahotsava” (grand festival), a term later used in dharmic contexts for public celebrations, processions, and communal rites.
