Matsya Purana — Yayāti’s Rule
कथं ज्येष्ठमतिक्रम्य कनीयान् राज्यमर्हति एतत्संबोधयामस्त्वां स्वधर्ममनुपालय //
kathaṃ jyeṣṭhamatikramya kanīyān rājyamarhati etatsaṃbodhayāmastvāṃ svadharmamanupālaya //
How can the younger be fit to rule the kingdom, bypassing the elder? We admonish you about this—uphold your own dharma.
Nothing directly—this verse is ethical-political instruction (rajadharma), focusing on rightful succession and adherence to svadharma rather than cosmology or pralaya.
It frames kingship as a dharmic trust: political authority should follow rightful order (the elder’s prior claim), and the intended ruler is urged to maintain svadharma—governing in accordance with inherited duty and moral law.
No vastu, temple-building, or ritual procedure is mentioned; the takeaway is governance-ethics—legitimacy arises from dharma, not mere power.
