Matsya Purana — Vishnu’s Battle with Mathana
स तेन विद्धो व्यथितो बभूव दैत्येश्वरो विस्रुतशोणितौघः ततो ऽस्य किंचिच् चलितस्य धैर्याद् उवाच शङ्खाम्बुजशार्ङ्गपाणिः //
sa tena viddho vyathito babhūva daityeśvaro visrutaśoṇitaughaḥ tato 'sya kiṃcic calitasya dhairyād uvāca śaṅkhāmbujaśārṅgapāṇiḥ //
Pierced by that blow, the lord of the Daityas was pained, as torrents of blood streamed forth. Then, seeing his courage falter slightly, the Bearer of the conch, lotus, and Śārṅga bow spoke to him.
This verse does not describe Pralaya directly; it depicts a combat moment where a Daitya-lord is wounded and Vishnu (identified by conch, lotus, and Śārṅga) prepares to address him.
Indirectly, it highlights steadiness (dhairya) under crisis: the Daitya’s courage wavers, and the narrative frames composure and moral instruction as following force—an ethical pattern often applied in Purāṇic teaching about righteous governance and self-control.
Architecturally, the key relevance is iconographic: Vishnu is marked by the conch (śaṅkha), lotus (padma/ambuja), and Śārṅga bow—attributes used in pratिमा-lakṣaṇa (image-identification) for correct temple imagery and ritual visualization.
