Matsya Purana — The Advent of Narasiṃha and Hiraṇyakaśipu’s Weapon-Assault
गान्धर्वमस्त्रं दयितम् असिरत्नं च नन्दकम् प्रस्वापनं प्रमथनं वारुणं चास्त्रमुत्तमम् अस्त्रं पाशुपतं चैव यस्याप्रतिहता गतिः //
gāndharvamastraṃ dayitam asiratnaṃ ca nandakam prasvāpanaṃ pramathanaṃ vāruṇaṃ cāstramuttamam astraṃ pāśupataṃ caiva yasyāpratihatā gatiḥ //
Beloved to him was the Gāndharva missile; he also possessed the jewel-like sword Nandaka—along with the sleep-inducing weapon, the crushing (Pramathana) weapon, and the excellent Vāruṇa weapon. He further held the Pāśupata weapon, whose course is unstoppable.
This verse is not about Pralaya; it is a heroic catalogue of astras (divine weapons), emphasizing irresistible force and invincibility rather than cosmology.
In the royal-ethics backdrop of Purāṇic narratives, such weapon-lists underscore a king’s kṣātra role: protection of subjects and maintenance of order, where mastery over astras symbolizes disciplined power rather than personal aggression.
No Vāstu or temple-rule is stated here; the closest ritual implication is that “astra” usage traditionally presumes mantra-authorization and controlled deployment, reflecting dharmic restraint in sacred technologies.
