Matsya Purana — The Array of the Gods: Description of the Vaiṣṇava Host and the Lokapālas
स राजराजः शुशुभे युद्धार्थी नरवाहनः उक्षाणमास्थितः संख्ये साक्षादिव शिवः स्वयम् //
sa rājarājaḥ śuśubhe yuddhārthī naravāhanaḥ ukṣāṇamāsthitaḥ saṃkhye sākṣādiva śivaḥ svayam //
That emperor among kings shone forth, eager for battle; mounted on a bull in the thick of combat, he appeared as if he were Śiva himself made manifest.
This verse does not address pralaya or cosmology; it is a heroic royal description, using Śiva-imagery to magnify the king’s martial splendor.
It reflects the kṣatriya ideal: the king is portrayed as battle-ready and radiant in the arena, implying the royal duty of protection and decisive action against threats.
No Vāstu or temple-building rule is stated, but the bull-mount and ‘like Śiva’ comparison echoes iconographic conventions (Śiva associated with the bull/Nandin motif), useful for interpreting Purāṇic imagery.
