What was the deeper purpose of Sai Baba's incarnation and arrival in Shirdi, as interpreted by Chapter 39?

Chapter 39 presents a profound theological interpretation of Sai Baba's arrival, suggesting it was a deliberate act of divine grace rather than a coincidence. The text explicitly states that Sai took on his incarnation and came to Shirdi of his own accord, driven by a 'great concern for the upliftment of his devotees.' The primary beneficiaries of his grace were identified as the 'dull-witted, the fallen, and the poor,' as well as simple and faithful people who lacked formal vows, penance, or sacraments. According to this chapter, Sai's mission was to uplift these very souls, demonstrating his immense compassion for the humble and marginalized.
