Greek Mythology: The story of Eros and Psyche (Cupid and Psyche) Wiki: Cupid and Psyche is a story originally from Metamorphoses, written in the 2nd century AD by Lucius Apuleius Madaurensis (or Platonicus). The tale concerns the overcoming of obstacles to the love between Psyche, "Soul" or "Breath of Life" and Cupid (Latin Cupido, "Desire") or Amor ("Love", Greek Eros ’′Ερως), and their ultimate union in a sacred marriage. Although the only extended narrative from antiquity is that of Apuleius, Eros and Psyche appear in Greek art as early as the 4th century BC. The story's Neoplatonic elements and allusions to mystery religions accommodate multiple interpretations, and it has been analyzed as an allegory and in light of folktale, Märchen or fairy tale, and myth.

Carl Gustav Jung was born in Kesswil, Switzerland, and grown up to be one of the most influential psychologists and psychiatrists. In response to Sigmund Freud's psychoanalysis, he founded analytic psychology and developed the concepts of extravert and introvert personality. His ideas in psychology have propelled millions of people to undergo psychotherapy. He had also worked as a research scientist at Burghölzli, a psychiatric hospital in Zurich, Switzerland.

The Self in Jungian psychology is one of the Jungian archetypes, signifying the unification of consciousness and unconsciousness in a person, and representing the psyche as a whole. The Self, according to Carl Jung, is realized as the product of individuation, which in his view is the process of integrating one's personality. For Jung, the Self is symbolized by the circle (especially when divided into four quadrants), the square, or the mandala.
