Can you explain the story of the woman who wanted to fast and the lesson Baba taught her, as described in Chapter 32?

Chapter 32 introduces the story of a woman whose mind was set on visiting Shirdi and observing a three-day fast without any food. However, the chapter explains how this firm resolve was ultimately broken. Sai Baba had her make puranpolis and then ensured she ate them to her heart's content. The profound lesson embedded in this act, as highlighted in Chapter 32, is that "wearing out the body for others' sake - this blessed act is true welfare." This suggests that selfless service and action can be a higher form of spiritual practice than asceticism like fasting.
