Both Bhagirath and Basanti are disabled and live in penury at Dasrathnagar Dalit tola near Gahlaur in Gaya district, about 100 km from state capital Patna.
"I heard that a hero is coming to our village soon. We will tell him the real story of our lives full of misery," Bhagirath said in Magahi, a local dialect, in reference to Aamir Khan's proposed visit to see the road and meet the villagers.
Dasrath Manjhi had single-handedly carved out a 360 feet long, 30 feet high and 30 feet wide passage by cutting through a hill near Gahlaur with a hammer and chisel, working day and night. He died in 2007 after a battle with cancer.
The hill was between Attari and Wazirgunj blocks in Gaya district. Thanks to Manjhi, the village blocks have been brought closer. Manjhi began his uphill work when his wife was injured and he had to go around the mountains to reach the nearest hospital.
Basanti, who said she was proud to be the daughter-in-law of Dasrath - popularly known as "Mountain Man" - said she will request Aamir Khan to telecast their real story to the world.
"We have been left in the lurch, ignored by politicians and officials despite repeated assurances to help us," she said.
"We have been neglected by the state government and the district administration. No one has helped us to ensure a better life for us."
What pains her is that she and her husband beg for money for an annual ritual in memory of Dasrath.
Bhagirath and Basanti work in the village primary school as cooks for preparing the mid-day meal for children. Both of them are paid Rs.1,000 a month.
Aamir Khan reportedly said he will visit Dasrathnagar to dedicate this season's first episode of "Satyamev Jayate" to Dasrath Manjhi. The episode, set for telecast March 2, will be dedicated to a man who made the impossible possible with his hard work and dedication.
