What was Sai Baba's stated purpose for coming to Shirdi, and who were the primary beneficiaries of his grace as described in Chapter 39?

Chapter 39 explains that Sai Baba's arrival in Shirdi was a deliberate act of his own accord. His primary purpose was the upliftment of his devotees, for whom he felt 'great concern.' The chapter poses a rhetorical question, asking who else but Sai would uplift certain types of people. It then specifies that his grace was particularly aimed at the 'dull-witted, the fallen, and the poor,' as well as 'those without vows, penance, or sacraments.' In essence, as this chapter reveals, he came for the simple and faithful people.
