Can you explain the lesson behind the story of the woman who wanted to fast in Chapter 32?

Chapter 32 introduces the story of a female devotee whose mind was set on having Baba's darshan and observing a strict fast for three days. However, Sai Baba intervened and broke her firm resolve. The text explains how an occasion arose where she was made to prepare and then eat puranpolis to her heart's content. The profound lesson embedded in this incident, as highlighted in Chapter 32, is that "wearing out the body for others' sake - this blessed act is true welfare." This implies that selfless service and contributing to the well-being of others is a superior form of devotion compared to rigid personal austerities like fasting. Baba orchestrated this experience to make her understand this principle in a way she would never forget.
