How does Chapter 25 characterize Sai Baba and the nature of devotion required to please Him?

Chapter 25 portrays Sai Baba in the highest terms, calling him an "ocean of mercy," the "manifest incarnation of God," and the "Supreme Brahman." He is also described as the "Crest-jewel of Saints" and the "Fulfiller of desires." The chapter emphasizes that what Sai Baba desires above all is "one-pointed devotion." It clarifies that a devotee who possesses unwavering faith and devotion will have all their desires fulfilled. The text reinforces this by referencing Krishna's words to Uddhava, stating that the Sadguru is a form of God and should be worshipped with love, which is the very definition of one-pointed devotion as described in Chapter 25.
