Matsya Purana — Origin of Soma
स सोममेवाभ्यगमत्पिनाकी गृहीतदीप्तास्त्रविशालवह्निः अथाभवद् भीषणभीमसेनसैन्यद्वयस्यापि महाहवो ऽसौ //
sa somamevābhyagamatpinākī gṛhītadīptāstraviśālavahniḥ athābhavad bhīṣaṇabhīmasenasainyadvayasyāpi mahāhavo 'sau //
Then Pinākī (Śiva), having taken up blazing weapons of vast, fire-like brilliance, advanced straight toward Soma (the Moon). Thereupon a dreadful, great battle arose—terrifying to behold—for the armies on both sides.
This verse does not directly describe Pralaya; it depicts a cosmic-scale divine conflict, emphasizing the overwhelming power and radiance of Śiva’s weapons and the terror of a battle that shakes both sides.
Indirectly, it models the Purāṇic theme that power must be exercised with discernment: even divine confrontations produce widespread fear and disorder, implying that rulers should avoid needless escalation and protect their people from the chaos of war.
No explicit Vāstu or temple-ritual rule appears in this verse; its ritual takeaway is symbolic—Śiva as Pinākī embodies martial and protective potency often invoked in rites for protection (rakṣā) and removal of fear.
