Matsya Purana — Dynastic Genealogies: Paurava–Anu Lines
जनमेजयस्य राजर्षेर् महाशालो ऽभवत्सुतः आसीद् इन्द्रसमो राजा प्रतिष्ठितयशाभवत् //
janamejayasya rājarṣer mahāśālo 'bhavatsutaḥ āsīd indrasamo rājā pratiṣṭhitayaśābhavat //
To the royal sage Janamejaya was born a son named Mahāśāla. He became a king equal to Indra, and his fame stood firmly established.
This verse is genealogical and does not address pralaya; it records succession in a royal lineage and the renown of a king.
By praising Mahāśāla as “Indra-like” and “firm in fame,” the verse reflects the Purāṇic ideal that a king earns lasting renown through strong rule, protection of subjects, and dharmic governance.
No Vāstu, temple-building, or ritual procedure is mentioned; the focus is solely on dynastic succession and royal reputation.
