What is Kalikas problem

Why does she keep on plotting against Kumud... can she not let her live in peace.?

Kallika is sick in the head! She is SO jealous of Kumud for marrying Pramad. She is also jealous of Kumud for having someone who loves her as much as Saras! She just can't stand to see her happy. In her opinion, Kumud has everything she wanted but never got! What she dosent understand is that Kumud got all this because of the type of person that she is!! IF she was like Kalika, then she would NEVER get what she has! But people like Kalika only know how to blame and hate.

She needs to visit the doctor, she seriously doesn't know what she wants
