When Anandi met Akiraj for second time she became aware that her daughter has become an balika vadhu.
She just picked word balika vadhu and took sort of oath to remove this bad practices which was already her passion instead of taking oath that she would do every thing to search and find Nandini.
Her goal was not right from the start.
Bal vivah was not the reason for her daughter's kidnap and further plight. She was kidnapped for taking revenge not because Akhiraj was looking for a bride for his minor son.
News of Bal vivah of Nandini should have actually ensured Anandi that her girl is still at Akhiraj's house , he would neither sell off his son's wife nor he would now kill her.
Her task had became easier after that , her search has become limited to Akhiraj, all she has to do was to search Akhiraj , she knew his face , he was living in a near by village . Give advertisements, announce awards, hire detectives, go to check near by villages one by one .
All this would have rewarded in discovery of Nandini in few months , if not few in months then in few years but decade is passed and she still is waiting for her daughter and pining for her in the darkness of night. But in the day light no urgency can be discovered in her demeanour .
