Matsya Purana — Kārtavīrya Arjuna’s Solar Boon and the Genealogy from Kroṣṭu to the Yādava Lines
*सूत उवाच आदित्यो द्विजरूपेण कार्तवीर्यमुपस्थितः तृप्तिमेकां प्रयच्छस्व आदित्यो ऽहं नरेश्वर //
*sūta uvāca ādityo dvijarūpeṇa kārtavīryamupasthitaḥ tṛptimekāṃ prayacchasva ādityo 'haṃ nareśvara //
Sūta said: The Sun-god (Āditya), having assumed the form of a brahmin, approached Kārtavīrya and said, “O lord of men, grant me a single act of satisfaction (a meal/charitable hospitality); I am Āditya.”
This verse does not address pralaya; it belongs to a royal-legend setting where a deity (the Sun) appears in disguise to test or engage a king, highlighting ethical conduct rather than cosmic dissolution.
It foregrounds atithi-sevā (hospitality to a guest), a core dharma for householders and especially rulers: even when the visitor is unknown (here, a brahmin-form), the king is expected to provide food/charity that brings “tṛpti” (satiation and contentment).
No Vāstu or temple-building rule is stated in this verse; the ritual-ethical takeaway is the importance of honoring a guest (and, by extension, honoring the divine presence that may come veiled in ordinary forms).
