What does Chapter 25 reveal about Sai Baba's expectations from his devotees and the rewards of devotion?

Chapter 25 clearly states that Sai Baba is the "supreme embodiment of mercy" who desires only "one-pointed devotion" from his followers. The text emphasizes that a devotee who is faithful and filled with this kind of devotion will lack nothing in attaining their desires. According to this chapter, once one-pointed faith is established, Sai wards off all misfortunes, removes suffering, and grants the desired objects. The introduction to Damu Anna's story reinforces this, promising that listening to it will demonstrate how the "Guru-Mother is an 'Ocean of Mercy'."
