Matsya Purana — Yayāti’s Forest-Renunciation
*शौनक उवाच एवं स नाहुषो राजा ययातिः पुत्रमीप्सितम् राज्ये ऽभिषिच्य मुदितो वानप्रस्थो ऽभवन्मुनिः //
*śaunaka uvāca evaṃ sa nāhuṣo rājā yayātiḥ putramīpsitam rājye 'bhiṣicya mudito vānaprastho 'bhavanmuniḥ //
Śaunaka said: Thus King Yayāti, the son of Nahuṣa, having joyfully consecrated his desired son to the kingship by royal anointing, entered the vānaprastha stage—the forest-life—and became like a muni, a sage-ascetic.
This verse does not discuss pralaya; it focuses on dynastic history and the life-stage transition of a king after installing his heir.
It highlights a Rajadharma ideal: a king should ensure stable succession by consecrating a qualified heir, then—having fulfilled worldly obligations—may enter vānaprastha, moving toward renunciation and spiritual discipline.
The key ritual element is royal consecration (abhiṣeka/abhiṣecana) of the heir; no Vāstu or temple-architecture rule is stated in this verse.
