How does Chapter 16 contrast the gifts of a Sadguru with those of a wish-fulfilling gem, the Chintamani?

Chapter 16 makes a profound comparison to illustrate the unparalleled generosity of a Sadguru. It explains that a wish-fulfilling gem, or Chintamani, is limited because it can only bestow what a person thinks of or desires. The Sadguru, however, operates on a much higher plane. The text highlights this by stating that the Guru gives the "Unthinkable Object," which is Brahman, to His devotee. This act is described as a great wonder. Thus, while the Chintamani fulfills worldly thoughts, the Sadguru, as described in Chapter 16, bestows the ultimate, transcendental reality that is beyond ordinary thought and desire, making Him the most generous giver in all three worlds.
