Matsya Purana — The Strategy to Defeat Tāraka: Pārvatī’s Birth
पुष्पवृष्टिं प्रमुमुचुस् तस्मिंस्तु हिमभूधरे जगुर्गन्धर्वमुख्याश्च ननृतुश्चाप्सरोगणाः //
puṣpavṛṣṭiṃ pramumucus tasmiṃstu himabhūdhare jagurgandharvamukhyāśca nanṛtuścāpsarogaṇāḥ //
On that Himalayan mountain, they released a showering rain of flowers; the foremost Gandharvas sang, and hosts of Apsarases danced.
It does not describe pralaya; it depicts a divine celebration motif—flower-rain, celestial song, and dance—used in Puranas to mark sanctity, victory, or divine approval at a sacred place.
Indirectly, it supports the Matsya Purana’s broader ethic that dharmic acts—especially honoring sacred places and rites—invite auspiciousness; the celestial celebration functions as a narrative signal that the event or location is religiously meritorious.
Ritually, the “flower-shower” (puṣpavṛṣṭi) is a classic auspicious sign associated with successful worship, consecration, or sacred occurrences; the verse itself does not give Vastu/temple-building rules but fits the broader ritual vocabulary used in consecratory contexts.
