Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
दिशो ऽवरुद्धाः क्रुद्धेन सैन्यं चास्य निकृन्तितम् ततः क्रोधपरीतस्तु धनेशो जम्भदानवम् //
diśo 'varuddhāḥ kruddhena sainyaṃ cāsya nikṛntitam tataḥ krodhaparītastu dhaneśo jambhadānavam //
With wrath, he blocked off the directions, and his army too was cut down. Then, overcome by anger, Dhanesha (Kubera), confronted the demon Jambha.
This verse does not describe Pralaya; it depicts a martial-cosmic motif where the “directions” are obstructed, emphasizing the scale of conflict rather than cosmic dissolution.
Indirectly, it models the protective role of a ruler/guardian: when order is threatened (army destroyed, quarters blocked), the responsible authority (here Kubera as a lokapāla-like figure) must confront the aggressor to restore stability.
No direct Vāstu or ritual rule is stated; however, “blocking the directions” echoes a common sacred-geographic idea that the quarters must remain ritually and cosmically unobstructed—an underlying principle often assumed in temple orientation and protective rites.
