Mahamaya by Rabindranath Tagore

The theme of the story is about societal norms and romance. In ancient India, when you're in a family of nobility, fall in love with a shoddy man is forbidden. In that period, equal treatment is missing.

The story generally inform the readers the importance of social status. Wherein the poor can't be wed to a person who is has higher social status.

It also seeks to inform there readers that one single decision could change our lives forever. We can never bring back the things that are lost. What we can do is live with it. Just accept our decision good or bad.

And one more thing, In the story there's a trust issue. In real life, it also the same.
Love cannot survive if there is no trust between each other.
