What does Chapter 39 reveal about Sai Baba's divine purpose and his characteristics in his early years?

Chapter 39 reveals that Sai Baba's arrival in Shirdi was a deliberate act of grace. The text explains that "Out of great concern for the upliftment of his devotees, Sai takes this incarnation and comes to Shirdi of his own accord." His specific mission was to uplift the "dull-witted, the fallen, and the poor, those without vows, penance, or sacraments—simple and faithful people," demonstrating his compassion for the humble and sincere. This chapter also offers a glimpse into his early nature, mentioning that at the young age of eighteen, Sai had a "habit of solitude" and was fearless, willing to sleep anywhere, because "he saw the Lord everywhere." This points to his early attainment of divine consciousness and detachment from worldly comforts.
