In my opinion, the importance of an education should never be undermined. It always pays off in one way or another. However, it has not been established yet that Anandi is just going to run these adult-education centers and would not be studying further. I am pretty sure that she will continue studying as she tries to change the social structure around her village via education of the adults. Let's not write her education off just yet 😊.
Btw. interesting comparison with Anna's life there. I do hope though that Anandi's character etches hope for the society in a different light though.
