What is the symbolism in the wonderful old?

In "The Wonderful Wizard of Oz," the symbolism is rich and multifaceted. The journey to Oz represents the quest for self-discovery and personal growth, as each character seeks something they believe they lack: courage, heart, brains, and a sense of home. The yellow brick road symbolizes the path to one's goals and the adventures encountered along the way. Additionally, Oz itself serves as a metaphor for the illusion of authority and the idea that true power lies within oneself.
