Beyond the chance meeting with Chand Patil, what does Chapter 39 suggest was the deeper purpose for Sai Baba's incarnation and arrival in Shirdi?

Chapter 39 explains that while Chand Patil was the person who brought Sai Baba to Shirdi, he was merely an instrument in a larger divine plan. The text clarifies that Sai Baba came to Shirdi of his own accord, driven by a great concern for the spiritual upliftment of his devotees. His primary mission, as described in this chapter, was to help the "dull-witted, the fallen, and the poor," as well as simple and faithful people who lacked formal vows or penance. Therefore, Chapter 39 posits that Sai Baba's incarnation was a deliberate act of grace to uplift those most in need of a savior.
