What does Chapter 39 reveal about the purpose of Sai Baba's incarnation and his arrival in Shirdi?

Chapter 39 of the Sai Satcharitra states that Sai Baba's coming to Shirdi was not a chance event but a deliberate act of his own accord. The text asserts that Sai took this incarnation out of great concern for the upliftment of his devotees. It specifically asks who else but Sai would uplift the "dull-witted, the fallen, and the poor, those without vows, penance, or sacraments—simple and faithful people." This highlights that Sai's primary mission was to extend his grace to all, especially the humble and devout who might otherwise be overlooked, making his presence in Shirdi a purposeful act of compassion.
