What underlying reason does Chapter 39 provide for Sai Baba's incarnation and arrival in Shirdi, beyond the chance meeting with Chand Patil?

Chapter 39 presents a deeper, theological reason for Sai's presence in Shirdi, framing it as a deliberate incarnation rather than a coincidental event. The text clarifies that Chand Patil was merely an instrument in a divine plan. The true motivation for Sai's arrival was his 'great concern for the upliftment of his devotees.' As the chapter explains, Sai came of his own accord to uplift the 'dull-witted, the fallen, and the poor,' as well as those simple, faithful people who lacked formal vows, penance, or sacraments. This positions Sai's mission as one of universal grace.
