What are the primary stories and teachings outlined in the introduction of Chapter 32 of the Sai Satcharitra?

Chapter 32 introduces two main narratives that are described as being sweeter than nectar. The first is a wondrous story narrated by Sai Baba himself from his own mouth, detailing an unexpected Guru-darshan he experienced while in the forest. The second story concerns a woman who planned to observe a three-day fast. As Chapter 32 explains, her firm resolve was broken, and she was made to cook and eat puranpolis, teaching her the profound lesson that true welfare lies in wearing out the body for the sake of others, rather than in personal austerity.
