Based on Chapter 25, what is the relationship between faith, devotion, and the Sadguru's grace?

Chapter 25 establishes a direct and powerful link between faith, devotion, and receiving the Sadguru's grace. The text asserts that Sai Baba desires "one-pointed devotion" and that a devotee who is "faithful and filled with devotion lacks nothing in attaining their desires." This concept is reinforced by quoting Krishna's words to Uddhava: "The Sadguru is indeed My own form," suggesting that devotion to the Sadguru is devotion to God. The chapter promises that once a devotee establishes this one-pointed faith, Sai Baba actively wards off all their misfortunes, removes their suffering, and grants their desired objects, showcasing his immense love for his followers.
