What are some of the key metaphors and stories used in Chapter 19 to make complex spiritual ideas understandable?

Chapter 19 is rich with metaphors to explain profound spiritual truths. To illustrate the nature of devotion, it uses the image of offering a small wick to the mighty Sun. To explain the illusion of Maya, it compares the untainted Soul to a clear crystal that only appears to take on the colors near it. Another powerful metaphor mentioned in Chapter 19 is that of mistaking a rope for a snake, which signifies how we falsely superimpose the ego of 'I am the body' onto our true Self. Finally, the chapter uses the analogy of a tiny banyan seed containing the power of a vast tree to show the immense, unseen potential stored within.
