How does Chapter 16 compare a Sadguru to a wish-fulfilling gem (Chintamani), and what does this comparison reveal about the Guru's grace?

In Chapter 16, a significant comparison is drawn to highlight the unparalleled generosity of a Sadguru. The text states that a wish-fulfilling gem, or Chintamani, can only grant what a person thinks of or desires. However, the Sadguru's grace transcends this limitation. The chapter wonderfully explains that the Guru gives the "Unthinkable Object," which is identified as Brahman, to his devotee. This reveals that the Guru bestows something beyond the devotee's own limited imagination or worldly desires—the ultimate spiritual realization. This comparison underscores that the Guru's gift is not merely the fulfillment of material wants, but the bestowal of the highest, most profound state of being, which the disciple might not even know how to ask for.
