Based on the details in Chapter 39, what was Sai Baba's purpose for coming to Shirdi, and what were his habits in his early days?

Chapter 39 of the Shri Sai Satcharitra explains that Sai Baba's incarnation and arrival in Shirdi were driven by a profound purpose: the upliftment of his devotees. The text explicitly states that he came of his own accord out of "great concern" for them, especially the simple, fallen, poor, and faithful who lacked other means of spiritual progress. As for his early days, the chapter mentions that at the age of eighteen, Sai Baba had a habit of seeking solitude. He was completely without fear, willing to sleep anywhere at night, because his perception was that he "saw the Lord everywhere," indicating his constant state of divine consciousness.
