It was her duty to raise children wid utmost care and give them proper life.can we call a raising our own child as sacrifice.After death of her husband it was her duty. I know she went through lot of difficulties i appreciate her for it.But she always shows her past as if she didn't accomplish her duty rather sacrificed everything.
Neha lost her jus to help her mother that is called sacrifice.
Mamaji broke his LIC for neha medical treatment that will be a sacrifice.
Whatever ishwari deed were sacrifices and not her duty than dev is also sacrificing by taking care of whole family its not his duty.
I don't remember if any one said ishwari deed sacrifices but whatever cv's are showing regarding ishwari it seems to be sacrifice more than duty.
Just my POV.
