Matsya Purana — Paurava Genealogy
जरया संधितो यस्माज् जरासंधस्ततः स्मृतः जेता सर्वस्य क्षत्रस्य जरासंधो महाबलः //
jarayā saṃdhito yasmāj jarāsaṃdhastataḥ smṛtaḥ jetā sarvasya kṣatrasya jarāsaṃdho mahābalaḥ //
Because he was joined together by Jarā, he is therefore remembered as Jarāsandha. That mighty Jarāsandha became the conqueror of all the Kṣatriya warrior-kings.
Nothing directly—this verse is genealogical and etymological, focusing on how Jarāsandha got his name and his conquests, not on Pralaya.
It highlights a royal ideal of political dominance and military success among Kṣatriyas; it reflects the Purāṇic framing of kingship where conquest and supremacy are presented as marks of power (bala) and status.
None is stated in this verse; it does not discuss Vāstu, temple rules, iconography, or ritual procedure.
