Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
पर्वतैश्च शिलाशृङ्गैः शतशश्चैव पादपैः उपतस्थुः सुरगणाः प्रहर्तुं दानवं बलम् //
parvataiśca śilāśṛṅgaiḥ śataśaścaiva pādapaiḥ upatasthuḥ suragaṇāḥ prahartuṃ dānavaṃ balam //
Armed with mountains, rocky peaks, and hundreds upon hundreds of trees, the hosts of the gods arrayed themselves, ready to strike down the Dānava forces.
This verse does not describe Pralaya; it depicts a Devasura battle scene where the gods take up natural objects as weapons to restore cosmic order.
Indirectly, it supports the puranic ethic that righteous power is used to restrain destructive forces—paralleling a king’s duty to protect society and curb adharma.
No Vāstu or ritual procedure is taught here; the verse is primarily martial imagery (mountains, peaks, trees) used as weapons in divine combat.
