Carl Jung's theories focus on the concept of the collective unconscious, which suggests that all humans share a set of memories and ideas inherited from our ancestors. He believed that this unconscious mind influences our thoughts, feelings, and behaviors, often manifesting through archetypes—universal symbols and themes found in myths, dreams, and art. Another key aspect of Jung's work is the idea of individuation, a process of personal development where individuals integrate different parts of their psyche to achieve a balanced self. This journey helps people understand their true nature and fosters personal growth, leading to a more fulfilling life.
