Why does Chapter 16 state that a Guru is more generous than a wish-fulfilling gem (Chintamani)?

In Chapter 16, the generosity of the Guru is described as unparalleled in all three worlds. While a wish-fulfilling gem, or Chintamani, can only grant what a person thinks of or desires, the Sadguru's gift is far superior. The text states with great wonder that the Guru gives the "Unthinkable Object," which is identified as Brahman, to His devotee. This ultimate realization is something beyond ordinary thought or desire, making the Guru's gift infinitely more valuable and profound than any material or worldly boon that could be imagined from a gem.
