Now Yayaati and Devayaanee had a son, so Sharmishthaa also expressed her desire to Yayaati to have a son. Yayaati considered it according to Dharm so they also had a son.

After some time Devayaanee had three sons and Sharmishthaa had two sons. When Devayaanee came to know about this she got very angry and went to her father's house. When Yayaati heard of her leaving him, he also followed her. He explained the situation to Devayaanee and Shukraachaarya Jee but Shukraachaarya Jee gave him Shaap that "he should get that kind of old look in which a person looks ugly". Yayaati told him that this would affect his daughter also, so he said "OK, you can exchange your old age with somebody, if at all somebody is ready". Yayaati called his all sons and asked them to give him their youth in exchange of the old age Shukraachaarya gave to him, but nobody agreed upon this except his youngest son.  Then he exchanged his old age with the youth of his youngest son and enjoyed the worldly pleasures for long time. One day Vairaagya arose in his mind and he gave his youth back to his son, took his old age back and went to forest. His wives also went with him.

He has also contributed hymns to Rig Ved Sanhitaa
