Matsya Purana — Paurava Genealogy
परीक्षितः सुतो ऽसौ वै पौरवो जनमेजयः द्विर् अश्वमेधमाहृत्य महावाजसनेयकः //
parīkṣitaḥ suto 'sau vai pauravo janamejayaḥ dvir aśvamedhamāhṛtya mahāvājasaneyakaḥ //
Indeed, Janamejaya, the Paurava king, was the son of Parīkṣit; he performed the Aśvamedha sacrifice twice and became renowned as a great patron of the Vājasaneyi (Yajurvedic) tradition.
This verse does not address Pralaya; it focuses on dynastic history and the ritual achievements of King Janamejaya in the Paurava line.
It reflects the king’s dharma as guardian of Vedic order: supporting orthodox ritual lineages and performing major śrauta sacrifices (like Aśvamedha) to affirm sovereignty and public prosperity.
The ritual significance is central: Janamejaya is credited with performing Aśvamedha twice and being a major Vājasaneyi (Śukla Yajurveda) patron, indicating formal śrauta procedure and Vedic school affiliation.
