Using the analogies from the text, explain how the Soul remains pure despite its appearance in the world through Maya.

Chapter 19 explains that the Soul, while appearing in the world due to the actions of Maya, remains untainted and changeless. The text uses the analogy of a crystal, which may appear red, black, or yellow depending on the color of a nearby object, yet the crystal itself remains pure, colorless, and distinct. Similarly, the ego of 'I am the body' is presented as a false superimposition, like mistaking a coiled rope for a snake or seeing the glitter of silver on a seashell. This chapter teaches that the Soul is inherently self-luminous, pure consciousness, and fundamentally distinct from the body, senses, and mind.
