The Youngest Son, and the Only One Who Said Yes
Puru was the youngest son of King Yayati, born to his second wife Sharmishtha, and the last of the five sons Yayati approached after being cursed with premature old age by the sage Shukracharya, his first wife Devayani's father.
Each of Puru's four elder brothers had already refused Yayati's request: Yadu, Turvasu, Druhyu and Anu all declined to trade their youth for their father's old age, and each was cursed in turn for the refusal, a set of consequences told in fuller detail in Yadu's own dedicated story elsewhere in this series.
Puru, the youngest and by the ordinary rules of succession the least likely heir, agreed without hesitation. He took on his father's decrepitude, becoming physically old and weak while still a young man in years, and gave Yayati his own youthful vitality in exchange, allowing his father to continue enjoying the sensory pleasures that had been interrupted by the curse.
A Thousand Years of Pleasure, and the Realisation That Followed
Yayati, restored to youth through Puru's sacrifice, spent an extraordinarily long period, described in some tellings as a thousand years, indulging every sensory pleasure available to a king. The Mahabharata's account of this period is unusually candid for a devotional text: it does not skip past his indulgence or moralise about it immediately, but lets Yayati genuinely pursue pleasure at length before the story turns.
What eventually happened is that Yayati discovered indulgence itself has a ceiling. No matter how much pleasure he consumed, satisfaction never arrived, and he came to a realisation the text renders almost as a philosophical conclusion in his own voice: that desire is not satisfied by feeding it, only strengthened, the way ghee poured on fire makes it burn hotter rather than putting it out.
Having reached this understanding, Yayati returned to Puru and gave him back his youth, resuming his own old age willingly this time, no longer trying to escape it, and prepared to retire to the forest as an ascetic. Before doing so, he formally rewarded Puru for the sacrifice by naming him heir to the throne, passing over all four elder sons.
The Dynasty That Carries His Name
Puru's line becomes the Paurava dynasty, and generations down that line produce Bharata, whose own name eventually gives the subcontinent its Sanskrit name, and further down still, Kuru, whose story of ploughing Kurukshetra into sanctified ground is told elsewhere in this series.
From Kuru's line the dynasty continues through Shantanu, Bhishma's generation, Vichitravirya, and the eventual split into the Pandava and Kaurava households whose war the Mahabharata is built around. Every major royal figure on both sides of that war, cousins fighting cousins, descends in an unbroken line from Puru's willingness to take on his father's old age when none of his elder brothers would.
The tradition treats Puru's choice as a genuine model of filial devotion, distinct from mere obedience, since the text is clear that Puru was not compelled, only asked, and volunteered where four brothers with equal standing had already refused. That single act of willingness is what the entire Kuru-Pandava lineage, and by extension most of the Mahabharata's central cast, ultimately traces back to.
Frequently Asked Questions
Why did Puru agree to take his father's old age?+
As the youngest of Yayati's five sons, Puru was the only one willing to trade his youth for his father's curse of premature old age when Yayati asked each of them in turn. His four elder brothers had all refused.
Did Yayati keep Puru's youth forever?+
No. After an extended period of indulgence, described as a thousand years in some tellings, Yayati realised that desire is never satisfied by feeding it, and returned Puru's youth to him, resuming his own old age willingly and naming Puru his heir.
How is Puru connected to the Pandavas and Kauravas?+
Puru's line becomes the Paurava dynasty, which runs down through Bharata and Kuru to Shantanu, Bhishma's generation, and eventually the Pandava and Kaurava households of the Mahabharata. Every major royal figure in the war descends from Puru.
