In Freud's "Psycho-analysis", and Sophocles' "Antigone", the concept of inner tranquility is achieved from looking within oneself. The source of the character's, or patient's problems originate from external influences. Freud's method of psycho-analysis is based upon studying oneself in order to confront the root of one's strife's. Similar to Freud's method of psycho-analysis, Sophocles' dramatizes the characters in "Antigone" (ex. Creon, Antigone, Haemon...) to imply the theme that tranquility is gained through self evaluation, as opposed to foreign dominations . Both texts support the idea that in order to be emotionally centered, one must look within in order to become jubilant on the outside.
