Can you summarize the main themes and introductions presented in Chapter 47?

Chapter 47 serves as an introductory chapter that praises the divine nature of Shri Sai and the purifying power of his stories. It begins with salutations and describes Sai's holy face as an abode of bliss that destroys sorrows from infinite births. The chapter emphasizes that his merciful glance liberates devotees from the bonds of karma. As detailed in Chapter 47, it uses an analogy of the River Ganges seeking the dust from saints' feet for its own purification to highlight Sai's holiness. The author also claims that Sai himself is the true narrator, speaking through him. The chapter concludes by linking to the previous story about goats and introducing the moral of the upcoming story, which will focus on how the extreme greed for wealth leads to a person's downfall.
