Mann Kee Awaaz Pratigya

Shyam points out that the only fault in the Thakur family is that no one is literate. Pratigya is hurt to know that Sajjan had given money to Shyam and humiliated him. Shyam returns Sajjan's money and asks him to buy books for Pratigya. Will they buy books for Pratigya? Why is Thakurain shocked?
