Matsya Purana — Yayāti and His Sons: The Exchange of Youth and Old Age
*ययातिरुवाच यस्त्वं मे हृदयाज्जातो वयः स्वं न प्रयच्छसि जरादोषस्त्वयोक्तो यस् तस्मात्त्वं प्रतिपद्यसे //
*yayātiruvāca yastvaṃ me hṛdayājjāto vayaḥ svaṃ na prayacchasi jarādoṣastvayokto yas tasmāttvaṃ pratipadyase //
Yayāti said: “Though you were born from my very heart, you do not grant me your own youth. Therefore, the very affliction of old age that you have spoken of—may you yourself come to attain it.”
This verse does not address Pralaya; it belongs to a dynastic-ethical narrative where Yayāti invokes a curse connected to old age (jarā) and the consequences of refusal of filial support.
It frames a moral tension around filial duty and reciprocity: a son born “from the heart” is expected to support the father, while the father-king’s response shows how anger and desire can distort dharma and lead to harsh, fate-shaping words.
No Vāstu, temple-building, iconography, or ritual procedure is mentioned in this verse; its focus is interpersonal ethics and the karmic force of speech (a curse) in royal lineage narratives.
