What are the two main stories that are introduced in Chapter 32 of Sai Satcharita, and what is their stated purpose?

Chapter 32 introduces two key incidents that will be narrated. The first is a story that Sai Baba told from his own mouth about an unexpected and wondrous darshan of his Guru while he was in the forest. This story is described as extremely beneficial for listeners. The second story concerns a woman who resolved to visit Baba and fast for three days. The narrative explains how her resolve was broken and she was made to prepare and eat puranpolis. As described in Chapter 32, this was to teach her that true welfare lies in wearing out the body for the sake of others, a lesson she would never forget.
