Chapter 19 uses the analogy of a crystal appearing in different colors. What does this comparison illustrate about the nature of the Soul?

The analogy of the crystal in Chapter 19 serves to explain the true nature of the Soul, or Atma. The source text explains that just as a clear crystal may appear red, black, or yellow depending on the color of an object placed near it, the Soul may appear to be affected by the qualities of the physical world and Maya. However, like the crystal, the Soul itself remains intrinsically pure, changeless, formless, and distinct from all the colors it seems to reflect. This teaching from Chapter 19 emphasizes that the Soul is untainted by worldly experiences, even while being associated with the body, senses, and mind.
