Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
स्वर्गे शक्रानुयातेषु देवतूर्यनिनादिषु सुन्दर्यः परिनृत्यन्ति शतशो ऽप्सरसां गणाः //
svarge śakrānuyāteṣu devatūryaninādiṣu sundaryaḥ parinṛtyanti śataśo 'psarasāṃ gaṇāḥ //
In heaven, when Indra is being attended and followed, and the sounds of divine instruments resound, beautiful companies of Apsarases dance in their hundreds.
This verse does not discuss Pralaya; it depicts Svarga’s celebratory atmosphere—Indra’s retinue, divine music, and Apsarases dancing—highlighting the Purāṇic vision of heavenly enjoyment rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic idea that merit (puṇya) and righteous conduct can lead to heavenly attainments; it functions as a motivational backdrop for dharma rather than giving specific royal or household injunctions.
No Vāstu or temple-building rule is stated here; the ritual-aesthetic element is the ‘deva-tūrya’ (divine instrumental music) accompanying celestial worship and celebration in Indra’s heaven.
