Matsya Purana — Yayāti and His Sons: The Exchange of Youth and Old Age
*ययातिरुवाच पूरो प्रीतो ऽस्मि ते वत्स वरं चेमं ददामि ते सर्वकामसमृद्धार्था भविष्यति तव प्रजा //
*yayātiruvāca pūro prīto 'smi te vatsa varaṃ cemaṃ dadāmi te sarvakāmasamṛddhārthā bhaviṣyati tava prajā //
Yayāti said: “O Puru, my dear son, I am pleased with you. I grant you this boon: your lineage shall be prosperous, successful in its aims, and endowed with every desired blessing.”
This verse does not discuss Pralaya; it focuses on a royal boon within the Yayāti–Puru dynastic narrative, emphasizing continuity and prosperity of lineage.
It highlights a king’s dharmic role in rewarding virtue and loyalty through blessings that secure social stability—prosperous progeny and fulfilled aims (artha and kāma) are portrayed as outcomes of righteous conduct and proper succession.
No Vāstu, temple-building, or ritual procedure is stated in this verse; its significance is genealogical—legitimizing Puru’s line as divinely favored through Yayāti’s boon.
