Matsya Purana — Yayāti and His Sons: The Exchange of Youth and Old Age
*शौनक उवाच एवं स तुर्वसुं शप्त्वा ययातिः सुतमात्मनः शर्मिष्ठायाः सुतं ज्येष्ठं द्रुह्युं वचनमब्रवीत् //
*śaunaka uvāca evaṃ sa turvasuṃ śaptvā yayātiḥ sutamātmanaḥ śarmiṣṭhāyāḥ sutaṃ jyeṣṭhaṃ druhyuṃ vacanamabravīt //
Śaunaka said: Thus, after cursing Turvasu, King Yayāti addressed Druhyu—his eldest son born of Śarmiṣṭhā—and spoke these words.
Nothing directly—this verse is part of the dynastic (genealogical) narration, focusing on Yayāti’s family and succession after a curse, not on cosmic creation or pralaya.
It reflects royal governance through succession and accountability: a king’s actions (such as cursing or judging) lead to consequential decisions about heirs and the ordering of the dynasty.
None is explicit in this verse; it is narrative genealogy rather than Vastu Shastra, temple architecture, or ritual procedure.
