Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
पूरयामास वेगेन संछाद्य रविमण्डलम् जम्भो ऽपि परमेकैकं शरैर्बहुभिराहवे //
pūrayāmāsa vegena saṃchādya ravimaṇḍalam jambho 'pi paramekaikaṃ śarairbahubhirāhave //
With great speed he filled the sky, veiling the orb of the sun; and in that battle Jambha too was struck—each one in turn—by many arrows.
It does not teach Pralaya directly; the sun being “covered” is a battlefield hyperbole/omen-like image showing the overwhelming force of missile volleys, not cosmic dissolution.
Indirectly, it reflects the kṣātra ideal of decisive martial capability—swift, effective action in combat—often cited in Purāṇic ethics as a king’s duty to protect and subdue threats.
None explicitly; the verse is focused on warfare imagery (arrows, speed, sun-obscuring volley) rather than Vāstu, temple rules, or ritual procedure.
