Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
कुजम्भस्तत्समालोच्य दानवो ऽतिपराक्रमः अभिदुद्राव वेगेन पदातिर्धनदं नदन् //
kujambhastatsamālocya dānavo 'tiparākramaḥ abhidudrāva vegena padātirdhanadaṃ nadan //
Seeing that, the exceedingly valiant Dānava Kujambha, advancing on foot, rushed forward with speed, roaring at Dhanada (Kubera).
This verse does not address Pralaya; it depicts a battlefield moment where the Dānava Kujambha charges Kubera, emphasizing martial action rather than cosmology.
Indirectly, it reflects the Purāṇic theme of kṣātra-vīrya (martial valor) and the public challenge of an opponent—useful as narrative background to discussions of royal protection and courage, though no explicit rājadharma rule is stated here.
None is explicit in this śloka; it is a combat description and does not mention Vāstu, temple-building, iconography, or a ritual procedure.
