What are the main stories and themes introduced at the beginning of Chapter 32 of Sai Satcharitra?

Chapter 32 begins by recalling the passing of several devotees like Vijayanand and Megha, before introducing two main narratives for the chapter. The first is a highly anticipated story that Sai Baba will tell from his own experience about an unexpected and wondrous encounter with his Guru in a forest. As stated in Chapter 32, this story is meant to grant devotion and liberation. The second story concerns a woman who came to Shirdi intending to fast for three days, but Baba broke her resolve by having her prepare and eat puranpolis, teaching her that service for others is a form of true welfare.
