What does Chapter 39 reveal about Sai Baba's purpose for coming to Shirdi and his habits in his early days?

Chapter 39 of the Sai Satcharitra posits that Sai Baba came to Shirdi of his own accord, motivated by a deep concern for the spiritual upliftment of his devotees. The chapter specifies that he came to help the "dull-witted, the fallen, and the poor," as well as simple and faithful people who lacked formal vows or penance. It asserts that Sai was the one who would uplift them. The text also provides a glimpse into his early life, stating that at the age of eighteen, he had a habit of seeking solitude. He would sleep anywhere at night without fear, a practice attributed to his ability to see the Lord everywhere.
