The purpose of the Hero's Journey in mythological storytelling is to illustrate the universal process of personal transformation and self-discovery. This narrative structure commonly follows a hero who undergoes challenges, faces trials, and gains knowledge or insight. The journey often includes stages such as the call to adventure, facing obstacles, and returning home transformed. By depicting these adventures, myths not only engage the audience but also impart valuable lessons about courage, resilience, and the complex nature of the human experience, serving as an archetype for our own lives.
