How does Chapter 25 characterize Sai Baba and the nature of devotion required by his followers?

Chapter 25 portrays Sai Maharaj as a divine and compassionate figure, referring to Him as an "ocean of mercy," the "manifest incarnation of God," and the "Supreme Brahman." The text emphasizes that what Sai desires above all is "one-pointed devotion." This type of devotion is described as worshipping the Sadguru with love, recognizing that, as Krishna told Uddhava, "The Sadguru is indeed My own form." Chapter 25 assures that a devotee who possesses this faithful and unwavering devotion will lack nothing in attaining their desires, as Sai wards off their misfortunes, grants their wishes, and removes their suffering once such faith is established.
