Matsya Purana — Genealogy of Kaśyapa: Ādityas
एतेभ्यः पुत्रपौत्राणां कोटयः सप्तसप्ततिः महाबला महाकाया नानारूपा महौजसः //
etebhyaḥ putrapautrāṇāṃ koṭayaḥ saptasaptatiḥ mahābalā mahākāyā nānārūpā mahaujasaḥ //
From these ancestors arose seventy-seven crores of sons and grandsons—mighty in strength, vast in stature, of many forms, and radiant with great energy.
It reflects post-creation expansion: the text emphasizes the vast multiplication of beings through descendants, not dissolution; the focus is genealogical proliferation rather than Pralaya.
By highlighting sons and grandsons, it reinforces the Purāṇic ideal of sustaining lineage through dharmic household life—marriage, progeny, and orderly continuity of society that kings protect and householders uphold.
None is directly stated in this verse; it is a numerical-genealogical statement, not a Vastu or ritual prescription.
