Anima is a term used in psychology to refer to the unconscious feminine aspect of a man's personality. It was first introduced by Swiss psychiatrist Carl Jung, who believed that the anima was the inner self of a man and was responsible for his emotional responses. The term PSYCHE is also used to refer to the unconscious mind, while MANIA is a state of intense excitement or enthusiasm. The SOUL is often seen as the spiritual essence of a person, and is sometimes used interchangeably with anima.
