Devayaanee, Shukraachaarya Jee's daughter, was a very proud girl. Shukraachaarya Jee was the Purohit of Daitya Raaj Vrishparvaa (Daksh's daughter Danu's son). Vrishparvaa had a daughter named Sharmishthaa. Devayaanee and Sharmishthaa were good friends. Once they were playing in a pond with their friends. At that time Shankar Jee was passing by with Paarvatee Jee, so all girls came out of the pond and started getting dressed hurriedly. In this hurry Sharmishthaa had put on Devayaanee's clothes. At this Devayaanee got very angry. Both had an exchange of hot dialogs. As a result Sharmishthaa pushed Devayaanee in a dry well and came to her house. 

By chance Raajaa Yayaati came there in search of water. As he peeped in the well, he did not get water in the well, but found a girl. He took her out. Yayaati gave his cloth to cover her body, since she was without clothes. Then Devayaanee requested him to marry her saying that now she did not want that anybody else should hold her hand after this. Although this marriage was not in accordance to Shaastra and Dharm but Yayaati accepted it as his fate. 

Then Devayaanee came to her house and told everything, about Sharmishthaa's incident, to her father. Her father decided to leave this Purohitship and left the house along with his daughter. When Vrishparvaa got this news, he immediately came to request them to stay back. Shukraachaarya Jee said, "My happiness is in the happiness of my daughter, so whatever she says, if it is agreeable to you it is all right with me."  On asking, Devayaanee said, "I want Sharmishthaa and all her friends as my maids and wherever I go they should also go with me."  Sharmishthaa had to agree for this seeing the delicacy of the situation. So when Devayaanee was married to Yayaati, Sharmishthaa and her friends also went with her as her maids. (Read Yayaati here for its further details)

Shukraachaarya warned Yayaati not to take Sharmishthaa to his bed. But it happened. So Devayaanee got angry and came back from Yayaati's house and told everything to her father. Shukraachaarya gave Shaap to Yayaati that he would be very old and ugly. Yayaati told that it would affect his daughter also. Then Shukraachaarya relaxed it to that if somebody was ready to exchange it with his youth, he could do that. Then Yayaati exchanged it with his youngest son.

(Read Raajaa Bali before reading this). 

When Asur won in Devtaa and Asur war and Raajaa Bali won all Lok he did a Yagya to become the Swaamee of Trilok under the guidance of his Guru Shukraachaarya Jee. Devtaa went to Brahmaa Jee and prayed Him to stop him doing this. Brahmaa Jee went to Vishnu. He consoled Devtaa saying that he would brn in Kashyap and Aditi's house as Vaaman Avataar and will do something. So He incarnated as a Vaaman boy in Kashyap's house.

When Bhagvaan Vaaman came to Bali's palace for alms, Shukraachaarya advised him not to commit for anything because He was not an ordinary Braahman boy, He was Vishnu Himself, still Bali did not agree with his advice on the basis that "if He is Bhagvaan and has come for alms at my door, I am the most fortunate person in the world who will give something to Bhagvaan who gives to everybody. I don't want to lose this opportunity; and if He is not Vishnu, then there is no fear from him; third, I have already taken vow to give Him whatever He wants so I am not going to break that; fourth, nobody goes empty-handed from my house. So I cannot do that." 

Shukraachaarya Jee quoted him several passages from scriptures where one could take his words back, but Raajaa Bali did not listen to. When he didn't listen to him, he sat in the spout of the pot through which the water for Sankalp of donation was to be used. So when Raajaa Bali wanted to pour the water from that pot, because Shukraachaarya Jee sat in it, he stopped water from going out. Seeing water not coming out of the pot, Vaaman Bhagvaan took a blade of Kush grass and inserted in the spout which pierced Shukraachaarya Jee's one eye. He shook with pain and moved away from the way, thus leaving the way for water to go out. Thus Bhagvaan Vaaman let complete the Sankalp ceremony and saved Devtaa. (Read Bali for further description)
