What does Chapter 30 reveal about the duty of saints and the supreme power of Sai Baba's grace?

According to Chapter 30, the primary and "unavoidable" task for saints is the uplifting of their own devotees. The text positions Sai Baba as the "Acharya (teacher) of the assembly of saints," implying His preeminent status. While saints have this duty, the chapter emphasizes that the transformative power comes from divine grace. It states that upon whomever Sai bestows His grace, that person attains "inconceivable great power" and the ultimate knowledge of discrimination between Self and non-Self. This suggests, as per the teachings in Chapter 30, that while saints serve as guides, it is Sai's grace that is the ultimate catalyst for a devotee's spiritual liberation and empowerment.
