What was Sai Baba's primary purpose for incarnating and coming to Shirdi, as explained in Chapter 39?

Chapter 39 of the Sai Satcharitra explains that Sai Baba's arrival in Shirdi was not by chance but was a deliberate act of his own accord, driven by a deep concern for the spiritual upliftment of his devotees. While his journey with Chand Patil's wedding party was the apparent reason, the text clarifies his true purpose was to uplift and offer grace to the simple and faithful. Specifically, he came for the dull-witted, the fallen, the poor, and those who lacked formal religious practices like vows or penance. His mission was to guide these humble and devoted souls, whom no one else would uplift.
