Literary Criticism provides lenses to conduct a close and in-depth reading of the text which would expand the thoughts and imagination of the readers. Literary criticism proposes different dimensions to the same text and unlocks the door for interpretations. It also influences the readers to break away from the conventional beliefs and perceptions regarding a particular text. It helps to read, understand and interpret literature in a better way and enhance the evaluative and critical skills.

It is also beneficial to uncover the follies hidden behind certain fabricated ideas.
