Chapter 16 draws a comparison between a Sadguru and a wish-fulfilling gem (Chintamani). Could you explain this analogy and why the Guru is considered superior?

Chapter 16 presents a profound comparison to illustrate the unparalleled generosity of a Sadguru. A wish-fulfilling gem, or Chintamani, is said to grant whatever a person thinks of or desires. However, the Sadguru's gift is far superior. The text explains that the Guru gives the "Unthinkable Object," which is identified as Brahman, the ultimate reality. This gift is beyond the scope of worldly thought and desire. While the Chintamani fulfills imaginable wants, the Guru bestows the unimaginable state of union with the Absolute, making him the most generous giver in all three worlds.
