Can you provide a summary of the main stories and teachings introduced in Chapter 32 of the Sai Satcharitra?

Chapter 32 of the Sai Satcharitra serves as an introduction to several significant narratives. It begins by mentioning that a sweet incident, narrated by Sai Baba himself from his own mouth, will be shared. This story concerns an unexpected Guru-darshan Baba experienced in a forest and is described as extremely beneficial. As detailed in Chapter 32, another story is also previewed about a woman who intended to fast for three days but was lovingly persuaded by Baba to eat puranpolis, teaching her the lesson that "Wearing out the body for others' sake - this blessed act is true welfare." The chapter also introduces the powerful metaphor of the perishable "tree of worldly existence" to explain the nature of samsara.
