Matsya Purana — The Slaying of Jambha and the Rise of Tāraka: Divine Battle Formations
ततो जज्वलुरस्त्राणि ततो ऽकम्पत वाहिनी एकतस्तारको दैत्यः सुरसंघस्तु चैकतः //
tato jajvalurastrāṇi tato 'kampata vāhinī ekatastārako daityaḥ surasaṃghastu caikataḥ //
Then the missiles blazed forth, and the entire army shook. On one side stood the demon Tāraka, and on the other side stood the host of the gods.
This verse is not about Pralaya; it depicts a battlefield moment where divine astras blaze and the armies of gods and demons face each other, emphasizing cosmic order defended through conflict.
Indirectly, it reflects the kṣātra ideal of standing firm in a righteous conflict: organized forces, clear alignment of sides, and the use of sanctioned power (astra) to uphold dharma—principles often extended in the Purāṇas to kingly duty.
No Vāstu or temple-rule detail appears here; the technical term is astrāṇi (weapon-missiles), highlighting the ritualized/authorized nature of divine weaponry rather than architecture.
