Chapter 16 draws a comparison between a Sadguru and a wish-fulfilling gem. Can you elaborate on this comparison and explain why the Guru is considered superior?

In Chapter 16 of the Sai Satcharitra, the Sadguru is described as being far more generous than the mythical wish-fulfilling gem, or Chintamani. The text explains that while a Chintamani can only grant what a person can think of or desire, the Guru possesses the unique ability to give the "Unthinkable Object," which is identified as Brahman. This illustrates that the Guru's gift is not limited by the disciple's worldly imagination or desires. He provides the ultimate spiritual attainment that transcends material wants, making him the most generous giver in all three worlds and the ultimate refuge for a seeker.
