What is the main conflict in The Interpretation of Fairy Tales by Marie-Louise von Franz?

All fairy tales can be said to involve some aspect of the Self, Jung's term for the unified consciousness and unconsciousness of a person. The beginning premise of a tale might demonstrate some problem with the Self; for example, an instance in which the unconscious is not in harmony with the ego, or consciousness. The hero of the fairy tale then steps in as the archetypal symbol of positive transformation of the Self. By the end of the tale, the hero will achieve a unified, matured Self.
