How does Chapter 25 describe Sai Baba and the nature of devotion to him?

Chapter 25 describes Sai Baba in reverential terms, calling him an "ocean of mercy," the "manifest incarnation of God," and the "Supreme Brahman." The chapter emphasizes that Sai desires "one-pointed devotion" from his followers. It explains that a devotee who is faithful and filled with this kind of devotion will not lack anything in attaining their desires. This one-pointed devotion is defined as worshipping the Sadguru with love, which is a core principle highlighted in this section of the Shri Sai Satcharitra.
