Can you explain the story of the fasting woman as described in Chapter 32?

In Chapter 32, a story is introduced about a woman who came for Sai Baba's darshan with a firm resolve to fast for three days. However, the chapter explains how her plan was altered by Baba. The narrative highlights how she was unexpectedly made to prepare puranpolis and then eat them to her heart's content. The moral presented in Chapter 32 is that "wearing out the body for others' sake - this blessed act is true welfare." This incident was orchestrated to teach her a profound lesson about service and devotion that she would never forget, demonstrating that true spiritual practice goes beyond rigid fasting.
