What was Sai Baba's stated purpose for taking incarnation and coming to Shirdi, according to Chapter 39?

Chapter 39 clarifies that while Chand Patil was an instrument, Sai Baba came to Shirdi of his own accord. His primary purpose was driven by a great concern for the spiritual upliftment of his devotees. The chapter explicitly states that Sai's mission was to uplift specific types of people: the dull-witted, the fallen, and the poor. As detailed in Chapter 39, he came to help the simple and faithful individuals who lacked formal vows, penance, or sacraments, demonstrating his compassion for all, regardless of their social or religious standing.
