What does Chapter 39 reveal about the purpose of Sai Baba's incarnation and the types of people he sought to uplift?

Chapter 39 provides deep insight into Sai Baba's mission, stating he took his incarnation and came to Shirdi out of "great concern for the upliftment of his devotees." The text goes on to specify who he particularly came for, posing the rhetorical question: 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 passage from the chapter suggests that Sai's purpose was not just for the spiritually advanced, but specifically to extend grace and salvation to the marginalized, the simple, and those who lacked formal religious credentials, relying instead on pure, uncomplicated faith.
