Metaphors are a fundamental part of human communication, allowing us to understand abstract concepts by relating them to more concrete and familiar ideas. Across the podcast episodes provided, metaphors are used extensively to convey complex themes, emotions, and experiences.

For example, in the episode 'Lessons for Survival', the host explores metaphors related to birds and water to process difficult issues like the climate crisis and social injustice. Similarly, in 'Reprogram Your Identity', the 'dirty shirt' metaphor is central to the discussion of shedding old self-perceptions. Metaphors are also a key component of religious and spiritual teachings, as seen in the Joel Osteen episodes that use metaphors like the '$100 bill' and 'mouse/elephant' story to illustrate God's view of human worth.
