Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
अश्वमेधे ददौ राजा ब्राह्मणेभ्यस्तु दक्षिणाम् यज्ञे तु रुक्मकवचः कदाचित्परवीरहा //
aśvamedhe dadau rājā brāhmaṇebhyastu dakṣiṇām yajñe tu rukmakavacaḥ kadācitparavīrahā //
At the Aśvamedha sacrifice, the king granted the dakṣiṇā, the ritual fee, to the Brahmins. And in that very rite, Rukmakavaca—slayer of enemy heroes—on a certain occasion was present/performed.
Nothing directly—this verse is focused on royal ritual practice (Aśvamedha) and the giving of dakṣiṇā, not on pralaya cosmology.
It highlights a core royal duty in the Matsya Purana’s dharma framework: performing public Vedic rites and properly honoring Brahmins through dakṣiṇā, linking kingship with generosity and ritual responsibility.
Ritual significance: it underscores the Aśvamedha and the obligatory dakṣiṇā—an essential component of yajña completion—while naming Rukmakavaca as connected with the sacrificial context.
