Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
ततो नदत्सु तूर्येषु नृत्यन्तीष्वप्सरःसु च क्षीरोदस्योत्तरं कूलं जगाम हरिरीश्वरः //
tato nadatsu tūryeṣu nṛtyantīṣvapsaraḥsu ca kṣīrodasyottaraṃ kūlaṃ jagāma harirīśvaraḥ //
Then, as the musical instruments resounded and the Apsarases danced, Lord Hari—the Supreme Lord—went to the northern shore of the Ocean of Milk (Kṣīroda).
This verse does not describe pralaya directly; it presents a celestial, orderly scene—music, dance, and Hari’s movement—set around the Kṣīroda (Ocean of Milk), a realm typically associated with divine preservation rather than dissolution.
Indirectly, it models kingship/householder ideals of auspicious order (maṅgala): ceremonial music, regulated celebration, and reverent attention to the Lord’s presence—values echoed in Purāṇic ethics as markers of dharmic culture.
Ritually, the mention of tūrya (ceremonial instruments) and dance evokes temple/processional celebration (utsava) atmospherics; while no Vāstu rule is stated, it supports the Purāṇic emphasis on auspicious sound, procession, and devotional spectacle in sacred settings.
