Matsya Purana — Dhruva as Cosmic Pivot: Motions of Sun–Moon–Planets
द्वितीय आवहन्वायुर् मेघास्ते त्वभिसंश्रिताः इतो योजनमात्राच्च अध्यर्धविकृता अपि //
dvitīya āvahanvāyur meghāste tvabhisaṃśritāḥ ito yojanamātrācca adhyardhavikṛtā api //
The second is the ‘āvahana’ wind: those clouds are borne and pressed onward by it. Even from a distance of only a yojana from here, they appear distorted—by a measure of one-and-a-half in their form.
It describes a specific named wind that drives clouds and produces abnormal, distorted appearances—an atmospheric omen consistent with the Purana’s portrayal of destabilized natural order during Pralaya-related events.
Indirectly, it supports the Purana’s ethic of vigilance: rulers and householders should heed unusual natural signs as warnings, prompting protective measures (rituals, provisioning, and orderly governance) when large-scale calamity is impending.
No direct Vastu rule is stated here; the practical takeaway is ritual/observational—recognizing abnormal winds and cloud behavior as portents that may warrant appeasement rites (śānti) and preparedness rather than construction activity.
