Based on Chapter 39, for what purpose did Sai Baba come to Shirdi, and what were his habits in his youth?

Chapter 39 explains that Sai Baba's arrival in Shirdi was a deliberate act of grace. He came "of his own accord" with the purpose of uplifting his devotees, particularly the "dull-witted, the fallen, and the poor," as well as simple and faithful people who lacked formal vows or penance. The chapter also provides a glimpse into his early life, noting that at the age of eighteen, he had a "habit of solitude" and would sleep anywhere at night without fear. This fearlessness stemmed from his profound spiritual state, as he "saw the Lord everywhere."
