According to C.G. Jung in "Man and His Symbols," a person achieves a state of wholeness and fulfillment when they undergo the process of individuation. This journey involves integrating both the conscious mind and the unconscious, leading to inner harmony. When the different aspects of one's psyche coexist peacefully, an individual can experience a deeper sense of calm, productivity, and joy.

Jung emphasizes that this integration is essential for personal development. It allows individuals to embrace their full selves, cultivating a fertile inner landscape where creativity and happiness can thrive. Ultimately, the completion of individuation not only nurtures the individual but also enhances their interactions with the world around them.
