What does Chapter 25 reveal about the concept of one-pointed devotion and the role of a Sadguru?

Chapter 25 places great emphasis on one-pointed devotion as the primary quality Sai Baba desires in his followers. The chapter states that a devotee who is faithful and filled with devotion will have their desires fulfilled. It clarifies this concept by quoting Krishna's words to Uddhava: "The Sadguru is indeed My own form." Therefore, the text suggests that one-pointed devotion is expressed through worshipping the Sadguru with love. According to Chapter 25, when a devotee establishes this one-pointed faith, the Sadguru, Sai, in turn wards off all their misfortunes, grants their wishes, and removes their suffering, demonstrating the reciprocal nature of this sacred relationship.
