Matsya Purana — The Birth of Tāraka: Varāṅgī’s Lament
चचाल सकला पृथ्वी समुद्राश्च चकम्पिरे चेलुर्महीधराः सर्वे ववुर्वाताश्च भीषणाः //
cacāla sakalā pṛthvī samudrāśca cakampire celurmahīdharāḥ sarve vavurvātāśca bhīṣaṇāḥ //
The entire earth shook; the oceans trembled; all the mountains swayed, and dreadful winds began to blow.
It depicts classic Pralaya-style portents—earthquakes, agitated oceans, swaying mountains, and fierce winds—signaling a breakdown of ordinary cosmic stability.
As an omen-verse, it implies preparedness and dharmic steadiness in times of crisis—leaders should protect people and resources, while householders maintain discipline, charity, and ritual order when the world becomes unstable.
Though not giving Vastu rules directly, the imagery underscores why Vastu and ritual texts stress stable foundations, correct site assessment, and protective rites—because nature’s upheavals are treated as spiritually and materially consequential.
