Human psyche is a most puzzling area which can neither be easily predicted nor easily understood.Over the years, many scientists have analyzed the workings of mind but have never succeeded in graphing a clear sketch of the human mind.Psychodynamic approach to literature believes that all behaviors have a root cause; a cause that is often because of some unconscious motive.These inner motives evoke behaviorism and determine the formation of character in individual people.Paulo Coelho’s Adultery is one such story, which deals with the dynamics of a woman’s psyche. The protagonist’s evolution of character from the boredom of normal routine, to a passionate affair to the mental sufferings she undergoes and finally to the way she resolves everything to go back to her normal is beautifully traced by the author. This paper attempts to interpret the sub-conscious level of the protagonist’s mind and trace her evolution of character through psychoanalytic theory.
