What does Chapter 39 say about the character and purpose of Sai Baba's incarnation?

Chapter 39 portrays Sai Baba as a compassionate figure who came to Shirdi out of great concern for the spiritual upliftment of his devotees. The text explicitly states that Sai took this incarnation and came to Shirdi of his own volition, with Chand Patil being merely an instrument in this divine plan. His purpose was to uplift the 'dull-witted, the fallen, and the poor,' as well as simple and faithful people who lacked formal vows, penance, or sacraments. It also mentions that at the young age of eighteen, he had a habit of solitude and was without fear because he saw the Lord everywhere.
