Según el cómputo humano, tres mil años—junto con otros treinta años—se recuerdan como un «año de Saptarishi» (el año medido por el ciclo de los Siete Sabios).
It does not describe Pralaya directly; it provides a technical unit of sacred chronology (the Saptarishi-year) used to structure long cosmic and historical time spans that frame cycles of creation and dissolution.
By defining an authoritative time-measure, it supports dharma in practice—ritual calendars, royal record-keeping, and the traditional dating of lineages and eras that kings preserve as part of righteous governance.
No Vāstu rule is stated, but such time-reckoning is commonly used to time rites, consecrations, and calendrical observances—background chronology that supports correct ritual scheduling.
