Matsya Purana — Vishnu’s Battle with Mathana
शरैस्त्रिभिस्तस्य भुजं बिभेद षड्भिश्च शीर्षं दशभिश्च केतुम् विष्णुर्विकृष्टैः श्रवणावसानं दैत्यस्य विव्याध विवृत्तनेत्रः //
śaraistribhistasya bhujaṃ bibheda ṣaḍbhiśca śīrṣaṃ daśabhiśca ketum viṣṇurvikṛṣṭaiḥ śravaṇāvasānaṃ daityasya vivyādha vivṛttanetraḥ //
With three arrows he split the demon’s arm; with six he struck his head; with ten he shattered his banner. Then Viṣṇu, drawing his bow to the full, pierced the Daitya up to the end of his ear, as the demon’s eyes rolled wide in shock.
This verse does not describe Pralaya; it depicts Vishnu’s martial protection of cosmic order by defeating a Daitya—an action that, in Puranic theology, preserves the world from chaos rather than dissolving it.
The verse models the kṣatriya ideal of decisive action against adharma: a king is expected to protect society by restraining violent forces, just as Vishnu disables the demon’s limbs, leadership-symbol (banner), and capacity to harm.
No Vastu or ritual procedure is directly taught here; the only technical motif is the battle-symbol “ketu” (banner/standard), commonly used in Purāṇic literature as a sign of sovereignty and morale.
