Matsya Purana — Genealogy from Budha to Purūravas and Yayāti; Raji’s war episode; the Paurava...
तं विनिर्जित्य समरे विविधायुधपाणिना बुधपुत्रेण वायव्यम् अस्त्रं मुक्त्वा यशो ऽर्थिना //
taṃ vinirjitya samare vividhāyudhapāṇinā budhaputreṇa vāyavyam astraṃ muktvā yaśo 'rthinā //
Having defeated him in battle, the son of Budha—his hands bearing many kinds of weapons—released the Vāyavya (Wind) weapon, seeking glory.
This verse does not address Pralaya; it focuses on a battle scene and the release of the Vāyavya (Wind) astra for the sake of fame.
It reflects the kṣatriya ideal of martial prowess and victory in battle, while also hinting at the ethical tension of fighting for “yaśas” (personal glory) rather than solely for dharma.
No Vāstu or ritual procedure is specified; the technical point here is astravidyā—knowledge of specialized missiles like the Vāyavya astra.
