S. Lakshmanan's SPA Psycho Center in Puducherry represents Sigmund Freud's psychoanalysis. Freud (1856-1939) was an Austrian neurologist who founded psychoanalysis. He proposed that unconscious processes influence consciousness and proposed three parts of personality: the id, ego, and superego. Freud also developed his psychosexual stages of development from oral to genital and introduced concepts like the Oedipus complex and defense mechanisms. The document then provides descriptions of Freud's psychosexual stages and structures of personality.
