Can you give me an overview of the stories and teachings introduced in Chapter 32 of the Sai Satcharitra?

Chapter 32 of the Sai Satcharitra serves as an introduction to several key narratives and philosophical points. After briefly mentioning the passing of devotees like Megha and Tatya Saheb Noolkar, the chapter outlines two main stories to be told. The first is a significant event narrated by Sai Baba himself about an unexpected Guru-darshan he experienced in a forest. The second story concerns a woman who intended to fast for three days but was instead guided by Baba to prepare and eat puranpolis. As Chapter 32 explains, this was to teach her that serving others is a form of supreme welfare. The chapter also introduces the concept of the 'tree of worldly existence' and emphasizes that a Guru's grace is essential for true knowledge.
