How does Chapter 25 describe Sai Baba's nature and the type of devotion He expects from His followers?

Chapter 25 portrays Sai Baba as the "supreme embodiment of mercy" and an "ocean of mercy." The chapter begins with salutations that describe Him as the "manifest incarnation of God" and the "Supreme Brahman." According to the text, Sai desires "one-pointed devotion" from His followers. It emphasizes that a devotee who is faithful and filled with such devotion will not lack anything in attaining their desires. The chapter even draws a parallel to Krishna's words to Uddhava, stating, "'The Sadguru is indeed My own form,' said Krishna to Uddhava," reinforcing the idea that one should worship the Sadguru with love, which is the essence of one-pointed devotion as explained in this chapter.
