Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
*ऋषय ऊचुः किमर्थं तद्वनं दग्धम् आपवस्य महात्मनः कार्तवीर्येण विक्रम्य सूत प्रब्रूहि तत्त्वतः //
*ṛṣaya ūcuḥ kimarthaṃ tadvanaṃ dagdham āpavasya mahātmanaḥ kārtavīryeṇa vikramya sūta prabrūhi tattvataḥ //
The sages said: “For what reason was that forest—belonging to the great-souled Āpava—burned after it was overrun by Kārtavīrya? O Sūta, tell us the truth precisely.”
This verse does not discuss pralaya; it introduces a historical-legendary inquiry into a king’s act (the burning of a forest) and its true cause.
By questioning why a forest was burned, the sages implicitly spotlight royal accountability—kings’ displays of power must be examined for their ethical cause and consequences (harm to ascetics, property, and dharma).
No vastu/ritual procedure is stated in this verse; it functions as a narrative transition, setting up an explanation of events that may later carry dharmic or ritual implications.
