What are the main stories and teachings previewed in Chapter 32 of the Sai Satcharitra?

Chapter 32 serves as an introduction to several key narratives and philosophical points. It begins by recalling the passing of devotees like Vijayanand and Megha, then promises to share a sweet incident narrated by Sai Baba himself about an unexpected Guru-darshan he experienced in the forest. As detailed in this chapter, it also sets the stage for a story about a woman who intended to fast for three days but was instead taught a lesson about selfless service by being made to prepare and eat puranpolis. The chapter emphasizes that the words from Sai's mouth destroy sins and that true knowledge is impossible without a Guru's grace, preparing the reader for the profound lessons to follow.
