A Curse for Betraying Two Wives
King Yayati of the lunar dynasty married Devayani, daughter of the asura guru Shukracharya, as part of a settlement after Shukracharya's own bitter falling out with his student Kacha. Devayani came with a condition attached to her: her father insisted that Sharmishtha, daughter of the asura king Vrishaparva and formerly Devayani's proud rival, would go with her as an attendant, and that Yayati must never take Sharmishtha to his bed.
Yayati kept that promise for a while. Then Sharmishtha, resentful of serving the woman who had once been beneath her, approached Yayati directly during a season when Devayani was away, and asked to become his wife too, arguing that a kshatriya king marrying a second time was no sin. Yayati agreed, and for years kept the arrangement secret, fathering two sons on Devayani and three more on Sharmishtha without his first wife knowing where the second set of children came from.
Devayani found out eventually, the way these stories usually resolve: by seeing the children together and asking the wrong question at the wrong moment. She went straight to her father. Shukracharya was not interested in hearing Yayati's excuses. A king who deceives his wife, breaks a sworn condition, and lies for years is not someone Shukracharya was willing to protect with the ordinary indulgence granted to kings, and he cursed Yayati with jara, immediate and total old age, right there, mid-sentence, while Yayati was still a young man in the middle of his reign.
Yayati panicked, not unreasonably. He had barely begun to rule and had not finished, in his own estimation, tasting the pleasures a king was owed. He begged Shukracharya to reconsider. A rishi's curse, once spoken aloud, cannot simply be cancelled the way a promise can be broken. But Shukracharya, watching his own grandsons standing in the room, allowed a way out that was not quite mercy and not quite justice either: Yayati could hand his old age to someone else, if that person accepted it willingly, and take their youth in exchange for as long as he wanted.
Five Sons, One Answer
Yayati had five sons by then: Yadu and Turvasu from Devayani, Druhyu, Anu and Puru from Sharmishtha. He went to each one and asked, plainly, for their youth in exchange for his old age.
Yadu, the eldest, refused first, and by most tellings refused with an edge of moral objection - his father had lived exactly as he pleased for years and was now asking his own children to pay for it. Turvasu refused next. So did Druhyu and Anu. Yayati, stung, did not simply accept the refusals; he cursed each of the four in turn, declaring that their lines would not inherit his throne, and in some versions that their descendants would be pushed to the edges of Vedic society, becoming, in the genealogical shorthand the tradition later used, the ancestors of peoples outside the Vedic mainstream.
Only Puru, the youngest, said yes without an argument. He took on his father's old age on the spot and gave Yayati his own young body in return. Yayati ruled for what the text describes as a thousand years in that young body, chasing every pleasure a king could arrange, and at the end of it arrived at a realization the epic states almost as a proverb: desire is not put out by satisfying it, it only grows, the way a fire fed with ghee burns brighter rather than going out. Having understood that, he returned Puru's youth to him, took back his own age, and named Puru his heir over all four older brothers, on the plain ground that Puru alone had honored his father when it cost him something to do it.
Why the Mahabharata Opens Here
This is not a self-contained fable tucked into the Adi Parva for color. Puru's line becomes the Paurava dynasty, and several generations down that same line produces both the Kurus and the Pandavas - meaning every claimant to the throne at Kurukshetra is, strictly by descent, arguing over a kingdom that exists because one son once agreed to grow old for his father. Yadu's line, meanwhile, does not vanish into obscurity despite the curse; it becomes the Yadava clan, and several more generations down that line is where Krishna is born. Two of the epic's central bloodlines, the Kurus who fight the war and the Yadava kinsman who arbitrates it, both trace back to this single scene of a father asking his sons for their youth.
The Bhagavata Purana repeats the genealogy in its Ninth Skandha with the same basic shape, which is one reason the story survived so cleanly: two major textual traditions agree on it. What they leave open, and what later retellings have picked at, is whether Puru's obedience is straightforwardly virtuous. The epic frames it as ideal filial duty rewarded exactly as it should be. Girish Karnad's Kannada play Yayati, written in the twentieth century, reopens the question from Puru's wife's side, asking what it actually costs a young man to hand his life over to satisfy an old man's appetite, curse or no curse. Both readings sit on the same story without cancelling each other out, which is generally true of how the better Puranic tales get handled: the moral is rarely as settled as the plot summary makes it sound.
Frequently Asked Questions
Why didn't Shukracharya simply cancel the curse instead of creating a workaround?+
In Puranic logic, a curse spoken by a rishi in earnest cannot simply be withdrawn once uttered - it can only be modified or given a condition under which it lifts. Shukracharya was still Yayati's father-in-law and grandfather to his children, so even in anger he built in an exit that depended on someone else's free choice rather than erasing his own word.
What actually happened to the four sons who refused?+
Yadu became the ancestor of the Yadava clan, the lineage Krishna himself is later born into, so his branch was hardly erased from the epic's memory. Turvasu, Druhyu and Anu are named in the genealogies as founders of peoples placed outside the core Vedic political center, which the tradition uses as shorthand for being written out of the main line of kingship rather than out of history altogether.
Is Puru's sacrifice treated as purely admirable in the text?+
The Mahabharata itself presents it as the clearest possible case of a son honoring a father, and rewards it without ambiguity by making Puru the heir. It is later writers, most notably Girish Karnad in his play Yayati, who ask what such obedience actually costs the person giving it, particularly Puru's own wife, who has no say in the exchange at all.
Where does this story appear in the scriptures?+
It is told in the Mahabharata's Adi Parva as part of the genealogy leading to the Kuru line, and repeated with the same essential structure in the Bhagavata Purana's Ninth Skandha, which lists the descent of the lunar dynasty in detail.
