Question

What tactics does mumtaz use to gain control of lakshmi, both physically and emotionally?

Answer 1

Mumtaz does several things in order to control Lakshmi.
Firstly she uses physical violence as she whips and hits Lakshmi when she does not obey her commands.  So she physically abuses her in order to break her will.  She also starves her constantly, when she is defiant. She also uses emotional torture as she says that Lakshmi has to work to pay off the debts for her family. So Lakshmi is scared that something will happen to her family. 

Answer 2

Emotionally, Lakshmi was always threatened by Mumtaz telling her that she should work to pay off her family’s debt, and created a bond that won’t break in fear of hurting her family. Physically, Mumtaz uses whip to beat Lakshmi when she doesn’t do something well until there are bruises all over her body.
