Matsya Purana — Narasimha’s Victory over Hiraṇyakaśipu and the Catalogue of Apocalyptic Omens
ततश्चक्राणि दिव्यानि दैत्याः क्रोधसमन्विताः मृगेन्द्रायासृजन्नाशु ज्वलितानि समन्ततः //
tataścakrāṇi divyāni daityāḥ krodhasamanvitāḥ mṛgendrāyāsṛjannāśu jvalitāni samantataḥ //
Then the Daityas, filled with rage, swiftly hurled divine discus-weapons at the lion-king (Mṛgendra), blazing on every side.
This verse does not describe Pralaya; it depicts a combat moment where enraged Daityas employ celestial weapons, emphasizing Puranic warfare rather than cosmic dissolution.
Indirectly, it reflects the Purāṇic ethic that uncontrolled anger (krodha) drives destructive action; kings are repeatedly advised to master wrath and act with restraint even in conflict.
No Vāstu or ritual procedure is specified here; the main technical element is the ‘cakra’ as a divine weapon motif, often relevant to iconographic identification of Vishnu-related martial symbolism.
