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

The story of the woman who intended to fast is presented in Chapter 32 as a lesson in the nature of true spiritual welfare. Her mind desired to have Baba's darshan and remain fasting for three days. However, as verses 8 and 9 explain, her firm resolve was broken, and she was made to cook and eat puranpolis to her heart's content. The key takeaway, as stated in the text, is that "wearing out the body for others' sake - this blessed act is true welfare." This incident was orchestrated to make her understand this principle so profoundly that she would never forget it.
