Can you explain the lesson taught to the woman who intended to fast for three days, as detailed in Chapter 32?

In Chapter 32, a story is introduced about a woman who came to have Baba's darshan with the firm intention of fasting for three days. However, the chapter explains how her resolve was broken and she was made to prepare and eat puranpolis to her heart's content. The profound lesson embedded in this incident is that 'wearing out the body for others' sake - this blessed act is true welfare.' Through this experience, she was made to understand that selfless service holds a higher virtue than personal austerity, a teaching she was intended to never forget.
