What is the deeper purpose of Sai Baba's incarnation and arrival in Shirdi, as interpreted by the author in Chapter 39?

Chapter 39 of the Sai Satcharitra presents a profound interpretation of Sai Baba's arrival. While the narrative mentions Chand Patil discovering Sai and bringing him to Shirdi with a wedding party, the text emphasizes that this was merely the superficial cause. The author clarifies that 'Chand Patil was merely an instrument.' The true reason, as stated in this chapter, was Sai's great concern for the upliftment of his devotees. He took this incarnation and came to Shirdi of his own accord specifically to uplift the 'dull-witted, the fallen, and the poor,' and those simple, faithful people who lacked formal vows, penance, or sacraments.
