Listen now, just as it has been heard in the ancient Purāṇas and in the Vedas; having indeed heard it from great-souled Brāhmaṇas as they recite and expound.
This verse does not describe pralaya directly; it establishes textual authority—what follows is to be accepted as a received tradition heard in the Vedas and ancient Purāṇas from trustworthy, great-souled teachers.
It frames dharma as something learned through disciplined listening (śravaṇa) to Vedic and Purāṇic instruction from qualified Brāhmaṇas—implying that rulers and householders should ground policy and conduct in authenticated teachings rather than personal opinion.
No specific Vāstu or temple rule is stated here; the verse functions as a preface that legitimizes subsequent ritual/architectural prescriptions as being rooted in Vedic-Purāṇic transmission.
