How does Chapter 16 explain the Guru's supreme generosity, particularly in comparison to a 'wish-fulfilling gem'?

In Chapter 16, the Sadguru is described as the most generous giver in all three worlds. To illustrate this, the text makes a powerful comparison. It notes that a wish-fulfilling gem, or Chintamani, can only grant what a person thinks of or desires. The Sadguru's gift, however, is infinitely greater. The chapter wonderfully states that the Guru gives the "Unthinkable Object," which is Brahman, to His devotee. This ultimate gift of Self-realization is beyond the grasp of ordinary thought or desire, showcasing why the Guru's generosity is unparalleled and truly miraculous.
