Brahmaśirastra-pratisaṃhāra — Retraction and redirection of the supreme weapon
Sauptika Parva, Adhyāya 15
अस्त्रं ब्रह्मशिरो यत्र परमास्त्रेण वध्यते । समा द्वादश पर्जन्यस्तद्राष्ट्र नाभिवर्षति
astraṃ brahmaśiro yatra paramāstreṇa vadhyate | samā dvādaśa parjanyas tad rāṣṭra nābhivarṣati ||
Di negeri mana pun senjata Brahmaśiras ditangkis atau dimusnahkan oleh peluru ilahi tertinggi lainnya, di kerajaan itu awan tak menurunkan hujan selama dua belas tahun penuh.
व्यास उवाच
The verse teaches that the use of ultimate, world-affecting weapons in war carries collective karmic and social consequences: even if aimed at enemies, the fallout can punish an entire kingdom through famine-like drought, making such violence ethically catastrophic.
Vyāsa describes a dire consequence associated with the Brahmaśiras astra: when it is met and neutralized by another supreme missile, the land where this occurs becomes afflicted with a twelve-year failure of rains—an ominous warning within the Sauptika Parva’s context of extreme wartime acts.
