Matsya Purana — War of Devas and Dānavas: Yama and Kubera Defeated; Kālanemi’s Māyā and the A...
वायुना तेन चन्द्रेण संशुष्केण हिमेन च व्यथिता दानवाः सर्वे शीतोच्छिन्ना विपौरुषाः //
vāyunā tena candreṇa saṃśuṣkeṇa himena ca vyathitā dānavāḥ sarve śītocchinnā vipauruṣāḥ //
Afflicted by that wind, by the moon’s chilling influence, and by the frost that had dried up their strength, all the Dānavas were tormented—cut down by cold and left devoid of manly vigor.
It does not describe Pralaya directly; instead, it shows how cosmic elements (wind, lunar chill, frost) can act as overwhelming forces that weaken beings—an idea consistent with Purāṇic cosmology where nature itself becomes a divine instrument.
Indirectly, it suggests a dharmic lesson in strategy and governance: strength is not only physical—conditions, timing, and environmental factors can decide outcomes. A king (or householder) should act with foresight, discipline, and awareness of larger forces beyond mere bravado.
No explicit Vāstu or ritual procedure is stated in this verse; its takeaway is symbolic—‘cold’ as a force that drains vigor—sometimes echoed in ritual and ascetic contexts where control of bodily energies is emphasized.
