What does Chapter 49 teach about the nature of a Sadguru, using Sai Baba as the example?

Chapter 49 portrays the Sadguru, exemplified by Sai Baba, as a being of incomprehensible greatness. It begins by stating that even the Vedas and Puranas grew weary trying to praise the Sadguru fully, suggesting that silence is the most fitting tribute. However, the Sadguru's qualities are so compelling that they inspire speech. As described in the chapter, Sai is the "crest-jewel of all saints," a resting place for devotees, and the remover of worldly troubles. His divine play is inexpressible, and his art is inconceivable. The chapter emphasizes that the Sadguru is the embodiment of welfare and can only be known through his own grace.
