According to Chapter 25, what is the nature of Sai Baba and what does He desire from His followers?

Chapter 25 describes Sai Baba as an "ocean of mercy," the "manifest incarnation of God," the "Supreme Brahman," and the "Crest-jewel of Saints." He is portrayed as the ultimate refuge for devotees, the fulfiller of their desires. The text explicitly states that what Sai Baba truly desires from his followers is "one-pointed devotion." It further clarifies this by referencing Krishna's words to Uddhava: "The Sadguru is indeed My own form," suggesting that one should worship the Sadguru with love. Chapter 25 promises that for a devotee who is faithful and filled with such devotion, Sai wards off all misfortunes and grants their desires, removing their suffering.
