ग्रसमाना इवाकाशं मुष्णन्त इव मेदिनीम् मुखेभ्यः ससृजुः श्वासान् उच्छ्वसन्त इवोरगाः //

As though devouring the very sky, and as though stealing away the earth, they sent forth blasts of breath from their mouths—like serpents hissing as they exhale.
It uses apocalyptic metaphors—“devouring the sky” and “stealing the earth”—to depict destabilizing, world-consuming forces typical of pralaya portents, emphasized through violent, scorching breaths.
Indirectly, it functions as a warning motif: recognizing impermanence and cosmic upheaval encourages kings and householders to uphold dharma, perform prescribed rites, and govern/act without arrogance, knowing worldly stability is not absolute.
No direct Vāstu rule is stated; ritual significance is thematic—such pralaya-omens commonly frame the need for protective rites (śānti) and disciplined observance of dharma when terrifying natural/cosmic signs appear.
