Matsya Purana — Brahmā–Gāyatrī as a Divine Pair and the Early Genealogies of Creation
यस्मान्ममाभिभवता मनः संक्षोभितं शरैः तस्मात्त्वद्देहमचिराद् रुद्रो भस्मीकरिष्यति //
yasmānmamābhibhavatā manaḥ saṃkṣobhitaṃ śaraiḥ tasmāttvaddehamacirād rudro bhasmīkariṣyati //
Because, by your overpowering assault, my mind has been violently shaken by your arrows; therefore Rudra will soon reduce your body to ashes.
It does not describe cosmic Pralaya directly; it uses Rudra’s incinerating power (bhasmīkaraṇa) as a motif of swift destruction, echoing Rudra’s broader role as a force of dissolution.
Ethically, it underscores that violent aggression and mental torment inflicted on others invite swift retribution; the implied guideline is restraint, righteous conduct, and avoidance of adharmic hostility.
No Vāstu or temple-ritual instruction appears in this line; its ritual-theological takeaway is the recognition of Rudra’s fierce aspect as an agent of punitive purification through fire (ash-making).
