What are the two main stories that Chapter 32 of the Sai Satcharitra sets up for the reader, and what is their initial significance?

Chapter 32 introduces two significant narratives. The first is a story that Sai Baba will narrate from his own mouth about an unexpected and wondrous Guru-darshan he experienced while in a forest, which is described as being extremely beneficial and capable of granting devotion and liberation. The second story, as detailed in Chapter 32, concerns a woman who resolved to fast for three days while visiting Baba. However, her firm resolve was broken when Baba had her prepare and eat puranpolis, teaching her the profound lesson that "wearing out the body for others' sake" is a blessed act and constitutes supreme welfare.
