Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
आसीन्मरुत्ततनयौ वीरः कम्बलबर्हिषः पुत्रस्तु रुक्मकवचो विद्वान्कम्बलबर्हिषः //
āsīnmaruttatanayau vīraḥ kambalabarhiṣaḥ putrastu rukmakavaco vidvānkambalabarhiṣaḥ //
Marutta had a heroic son named Kambalabarhiṣ. And Kambalabarhiṣ had a learned son named Rukmakavaca.
This verse does not discuss pralaya; it functions as a genealogical notice, preserving the succession of kings (Marutta → Kambalabarhiṣ → Rukmakavaca) that Puranas use to map sacred history across ages.
By highlighting a ruler described as “heroic” and a successor described as “learned,” the verse implies the Purāṇic ideal of kingship: valor in protection and learning in governance—traits central to rājadharma even when not spelled out here.
No explicit Vastu or ritual rule appears in this verse; its significance is archival—anchoring later ritual/royal traditions to named lineages often cited in donations, temple patronage records, and Purāṇic historical framing.
