Matsya Purana — Inquiry into Yayāti’s Story and the Kacha–Devayānī Episode
स ब्रह्मचारी च तपोधनश्च सदोत्थितः कर्मसु चैव दक्षः कचस्य मार्गं प्रतिपत्स्ये न भोक्ष्ये प्रियो हि मे तात कचो ऽभिरूपः //
sa brahmacārī ca tapodhanaśca sadotthitaḥ karmasu caiva dakṣaḥ kacasya mārgaṃ pratipatsye na bhokṣye priyo hi me tāta kaco 'bhirūpaḥ //
“He is a celibate student and rich in ascetic merit, ever vigilant and skilled in duties. I shall take the path after Kaca; I will not eat, dear father—for Kaca is beloved to me and handsome.”
Nothing directly—this verse is a character-focused narrative statement praising Kacha’s brahmacarya and tapas, not a pralaya or cosmology passage.
It elevates virtues prized in dharma literature—discipline, vigilance, and competence in duty (dakṣatā). For householders and rulers, it implies that self-control and steadfastness underpin right conduct and reliable action.
No Vastu, temple-building, or ritual procedure is specified here; the technical emphasis is ethical/ascetic (brahmacarya, tapas) rather than architectural.
