Matsya Purana — Planetary Chariots
अलातचक्रवद्यान्ति वातचक्रेरितानि तु यस्मात्प्रवहते तानि प्रवहस्तेन स स्मृतः //
alātacakravadyānti vātacakreritāni tu yasmātpravahate tāni pravahastena sa smṛtaḥ //
As things set in motion by a wheel driven by the wind move like a whirling firebrand, and because from him those things are carried onward (flow forth), he is therefore remembered by the name Pravahastena (“the one whose hand causes the onward flow”).
This verse does not describe Pralaya directly; it uses a vivid motion-simile (whirling firebrand, wind-driven wheel) to define a name/term—suggesting a technical or classificatory context rather than cosmic dissolution.
Indirectly: it models precise definition and correct naming (nirukti/etymological clarification), supporting the Purana’s broader aim that rulers and householders follow well-defined rules in governance, ritual, and building practice.
The verse points to Vāstu/technical terminology: wind-driven motion and “onward flow” language can relate to practical considerations like ventilation, directional winds, or mechanical devices described in Vāstuvidyā-style sections, with the term “Pravahastena” explained by its function.
