Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
सम्प्राप्तो निमिमातङ्गो यावच्छक्रगजं प्रति तावच्छक्रगजो यातो मुक्त्वा नादं स भैरवम् //
samprāpto nimimātaṅgo yāvacchakragajaṃ prati tāvacchakragajo yāto muktvā nādaṃ sa bhairavam //
As Nimi’s great elephant advanced toward Indra’s elephant, Indra’s elephant likewise moved forward, letting out a terrifying roar like that of Bhairava.
This verse does not describe Pralaya or cosmogenesis; it focuses on a martial/narrative moment where opposing elephant-forces advance, emphasizing dread and power through the “bhairava” roar.
Indirectly, it reflects the Purāṇic ideal of royal might and readiness in conflict: the parallel advance of forces and the terrifying roar signal disciplined response and deterrence—traits associated with kṣatriya duty (protection and command).
No Vāstu or temple-building rule is stated here; the key takeaway is symbolic—“bhairava” as a marker of awe/terror, a tone sometimes echoed in ritual descriptions of fierce sounds (nāda) used to signify power and warding.
