Matsya Purana — Vishnu’s Battle with the Daityas: Astra-Combat
परिघेण निमिर्दैत्यो मथनो मुद्गरेण तु शुम्भः शूलेन तीक्ष्णेन प्रासेन ग्रसनस्तथा //
parigheṇa nimirdaityo mathano mudgareṇa tu śumbhaḥ śūlena tīkṣṇena prāsena grasanastathā //
The Daitya Nimi was struck with an iron club (parigha); Mathana with a mace (mudgara); Śumbha with a sharp śūla; and likewise Grasana with a prāsa, a javelin.
Nothing directly—this verse is a battle-catalogue line listing Asuras and the specific weapons used against them, not a cosmology or pralaya passage.
Indirectly, it reflects the Purāṇic ideal of kṣātra-dharma (the warrior-king’s duty): protecting order by confronting violent forces; however, this specific verse is descriptive rather than prescriptive.
No Vāstu or ritual procedure is stated here; the technical content is martial—naming weapons (parigha, mudgara, śūla, prāsa) used in combat.
