Chapter 16 compares the Sadguru to a wish-fulfilling gem. What is the key difference highlighted in the text?

Chapter 16 of the Sai Satcharitra draws a powerful distinction between a Sadguru and a wish-fulfilling gem, or Chintamani. While a Chintamani is praised for its ability to grant whatever material or worldly thing a person thinks of, the Guru's gift is infinitely greater. As the text of Chapter 16 wonderfully explains, the Guru gives the 'Unthinkable Object,' which is Brahman or ultimate reality, to His devotee. This highlights that the Sadguru's grace transcends mere worldly desires and bestows the highest spiritual attainment, something beyond the grasp of ordinary thought or imagination.
