Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
महायोगी तु स बलिर् बद्धो बन्धैर्महात्मना पुत्रानुत्पादयामास क्षेत्रजान्पञ्च पार्थिवान् //
mahāyogī tu sa balir baddho bandhairmahātmanā putrānutpādayāmāsa kṣetrajānpañca pārthivān //
That Bali, a great yogin, though bound by the bonds laid upon him by the noble one, nevertheless caused five sons to be born—sons begotten through the kṣetra-method—who became kings upon the earth.
This verse does not address pralaya; it focuses on dynastic continuity—how Bali’s lineage continues through five kṣetrajā sons despite his being restrained.
It highlights the dharmic priority of preserving lineage and social order: even under constraint, a ruler’s line is continued through an accepted procreative/legal mechanism (kṣetra), ensuring succession and stability.
No Vāstu, temple, or ritual procedure is specified in this verse; the technical term here is social-legal—kṣetrajā (field-born sons)—rather than architectural.
