Matsya Purana — The Battle for Tripura: Portents
अन्योन्यमुद्दिश्य विमर्दतां च प्रधावतां चैव विनिघ्नतां च शब्दो बभूवामरदानवानां युगान्तकालेष्विव सागराणाम् //
anyonyamuddiśya vimardatāṃ ca pradhāvatāṃ caiva vinighnatāṃ ca śabdo babhūvāmaradānavānāṃ yugāntakāleṣviva sāgarāṇām //
As they aimed at one another—crashing together, charging forward, and striking down—the tumultuous roar of the gods and the Dānavas arose, like the thundering of the oceans at the end of an age (yugānta).
It uses dissolution-language as a simile: the battle’s roar is compared to the oceans’ thunder at yugānta, evoking pralaya-like vastness and cosmic scale rather than describing an actual flood or dissolution event.
Indirectly, it frames warfare as overwhelming and consequential; in the Matsya Purana’s ethical atmosphere, such imagery underscores why rulers must restrain violence, act with discernment, and treat war as a grave last resort.
No direct Vāstu/ritual rule is stated; the key takeaway is symbolic—cosmic metaphors (like yugānta oceans) are used to magnify events, a common Purāṇic technique also seen in temple eulogies and ritual praises.
