Chapter 39 mentions Sai's incarnation. What was the stated purpose of his coming to Shirdi, and who were the intended beneficiaries of his grace?

According to Chapter 39, Sai Baba's arrival in Shirdi was not a chance event but a deliberate incarnation taken out of "great concern for the upliftment of his devotees." The text poignantly asks who else but Sai would uplift certain groups of people. It specifically identifies the intended beneficiaries as the "dull-witted, the fallen, and the poor," as well as those simple, faithful people who lacked formal vows, penance, or sacraments. This highlights his divine mission to offer grace to all, especially the humble and marginalized.
