Can you explain the incident with the woman who wanted to fast, as detailed in Chapter 32?

In Chapter 32, we learn of a woman whose mind was set on having Baba's darshan and observing a three-day fast without food. However, her firm resolve was broken by Sai Baba's intervention. The chapter explains how an occasion arose where she was not only made to prepare puranpolis but was also made to eat them to her heart's content. Through this experience, Baba imparted a deep lesson that wearing out the body for the sake of others is a blessed act and constitutes supreme welfare, a teaching she was made to understand so she would never forget it.
