Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
निहत्य रुक्मकवचः परान्कवचधारिणः धन्विनो विविधैर्बाणैर् अवाप्य पृथिवीमिमाम् //
nihatya rukmakavacaḥ parānkavacadhāriṇaḥ dhanvino vividhairbāṇair avāpya pṛthivīmimām //
Rukmakavaca, having slain those clad in golden armor and the other armor-bearing archers with many kinds of arrows, thus won possession of this earth.
This verse does not address Pralaya; it focuses on battlefield victory—defeating armored archers and securing dominion over the earth.
It aligns with Rajadharma: a king (as a Kshatriya) is expected to protect and govern territory, sometimes through warfare; the verse highlights martial competence (archery) as part of securing rightful rule.
No Vastu/temple-architecture or ritual procedure is mentioned; the technical focus is military—armor (kavaca) and arrows (bāṇa).
