According to Chapter 25, what is the nature of Sai Baba and the kind of devotion he desires from his followers?

Chapter 25 opens by describing Sai Maharaj as an "ocean of mercy," the manifest incarnation of God, the Supreme Brahman, and a great Yogeshwar. The chapter emphasizes that Sai is the supreme embodiment of mercy and desires only one-pointed devotion from his followers. It further explains, by referencing Krishna's words to Uddhava, that a Sadguru is the very form of God and should be worshipped with love. This, the text clarifies, is what is meant by "one-pointed devotion," which ensures a faithful devotee lacks nothing in attaining their desires.
