Chapter 15
Yayati
He asked his son for his youth, and came back a thousand years later to return it
The curse
Yayati was a king of the lunar line.
He was married to Devayani, the daughter of Shukracharya.
Sharmishtha, herself the daughter of an asura king, lived with Devayani as an attendant.
Yayati also entered into a relationship with Sharmishtha and kept it hidden.
When the truth came out, Shukracharya cursed him with immediate old age.
The exemption
Then he allowed one exception.
If one of Yayati's sons willingly gave him his youth, the two could exchange their ages.
Yayati had five sons.
He asked the elder four in turn.
Each refused.
The youngest
Finally he asked the youngest, Puru.
Puru agreed.
In a moment, the young son became old and the old father became young again.
A thousand years
Yayati then lived the life for which he had wanted his youth restored.
The Mahabharata says this continued for a thousand years.
At the end of that long experiment, he returned with a conclusion that became one of the episode's best-known teachings:
Desire is not extinguished by satisfying it. Feeding desire is like pouring ghee onto a fire — it only burns more fiercely.
Giving it back
Yayati returned Puru's youth and took back his own old age.
Then he gave Puru the kingdom as well, passing over his four elder brothers.
From Puru came the Puru line, and from that line, eventually, the Kurus of the Mahabharata.
Note: Yayati's story in full is found in the Adi Parva of the Mahabharata — Devayani, Sharmishtha, Shukracharya's curse, the five sons and Puru's giving of his youth. The fourth amsha of the Vishnu Purana carries the same story in short form alongside the genealogy of the lunar line. The line about desire never being quieted by indulgence is among the most quoted parts of the Mahabharata. Puru's receiving the kingdom began the Puru line, and from it the Kuru line — which is to say the Mahabharata's story moves on from this decision.
