How is the Guru's generosity described in Chapter 16, and how is it compared to a wish-fulfilling gem?

Chapter 16 portrays the Guru as the most generous giver in all the three worlds. It explains that while a wish-fulfilling gem, or Chintamani, can only grant what a person thinks of or desires, the Guru's gift is far superior. The chapter wonderfully illustrates this by stating that the Guru gives the 'Unthinkable Object,' which is Brahman, 'with great wonder to His devotee.' This highlights the Guru's role in bestowing the ultimate spiritual realization, something that transcends worldly desires and imagination, making him the ultimate refuge for a seeker.
