I heard Chapter 32 has a story about a woman who wanted to fast. What's the lesson there?

According to the introduction in Chapter 32, a woman arrived with the intention of observing a three-day fast without food. However, Sai Baba intervened in her plan. The chapter explains that an occasion arose where her firm resolve was broken. She was not only made to cook puranpolis but also to eat them to her heart's content. The key lesson highlighted in Chapter 32 is that 'wearing out the body for others' sake - this blessed act is true welfare.' This incident was meant to teach her a profound truth about fasting and devotion that she would never forget.
