Carl Gustav Jung (1875-1961), a Swiss physician and pioneer of psychoanalysis, is one of the greatest thinkers of the 20th century. Although his ideas have deeply influenced our modern cultural reality and he has been the originator of numerous revolutionary concepts such as synchronicity, the collective unconscious, archetypes, and complexes, he remains, I feel, largely known as an unknown. This is why I felt the compelling need to attempt to make the thought of this visionary accessible to the general public, which builds a bridge between psychology and quantum physics. It demonstrates how significant the human need for meaning and symbolic or spiritual life is for experiencing profound well-being. Jung's conviction led him away from Freud and prompted him to experiment and develop his theory of the "process of individuation": an amazing inner journey where each of us learns to establish a dialogue between our conscious and unconscious selves to become fully oneself and gain access to a sense of unity and deep joy. - F.
