Matsya Purana — Vishnu’s Battle with the Daityas: Astra-Combat
पर्वताभे गजे भीमे मदस्राविणि दुर्धरे आरुह्याजौ निमिर्दैत्यो हरिं प्रत्युद्ययौ बली //
parvatābhe gaje bhīme madasrāviṇi durdhare āruhyājau nimirdaityo hariṃ pratyudyayau balī //
Mounting a terrifying, mountain-like elephant—oozing rut and hard to restrain in battle—the mighty Daitya Nimi advanced to confront Hari (Viṣṇu).
This verse does not discuss Pralaya; it depicts a martial episode where the Daitya Nimi advances against Hari, emphasizing conflict and divine opposition rather than cosmological dissolution.
Indirectly, it reflects the Purāṇic ideal that unrighteous aggression (as embodied by a Daitya attacking Hari) invites decisive resistance; for kings, it underscores vigilance against adharma and the need to restrain destructive force—symbolized by the uncontrollable musth-elephant.
No Vāstu or ritual procedure is stated here; the technical focus is poetic war-imagery (battlefield, mount, musth), not temple-building or rites.
