Matsya Purana — Tārakāsura’s Austerity and Boon; Mobilization for War; Bṛhaspati’s Fourfold P...
कालशुक्लमहामेषम् आरूढः शुम्भदानवः अन्ये ऽपि दानवा वीरा नानावाहनगामिनः //
kālaśuklamahāmeṣam ārūḍhaḥ śumbhadānavaḥ anye 'pi dānavā vīrā nānāvāhanagāminaḥ //
Mounted upon a great black-and-white ram, the Dānava Śumbha advanced; and other heroic Dānavas too moved forth, riding on mounts of many kinds.
This verse does not address pralaya or cosmology; it focuses on a war-march scene, describing Śumbha and other Dānavas advancing on various mounts.
Indirectly, it functions as a narrative contrast: the organized mobilization of hostile forces underscores why rulers must maintain readiness, protection, and strategic vigilance—core themes often reinforced through Purāṇic warfare episodes.
No explicit Vāstu or ritual procedure is stated; the key technical term is vāhana (mount/vehicle), which is more relevant to mythic symbolism and later iconographic interpretation than to temple-building rules in this specific verse.
