Based on Chapter 39, what was Sai Baba's primary mission in coming to Shirdi and whom did he intend to uplift?

The text in Chapter 39 explains that Sai Baba's arrival was not accidental but a deliberate incarnation born out of great concern for the upliftment of his devotees. It poses the rhetorical question of who else but Sai would uplift certain types of people. The chapter explicitly states that his purpose was to help the dull-witted, the fallen, and the poor. He also came for the simple and faithful people who may have lacked formal vows, penance, or sacraments, demonstrating a mission focused on providing grace to the humble and marginalized.
