What lesson was imparted to the woman who wanted to fast for three days, as described in Chapter 32?

The introduction to Chapter 32 describes a woman who desired to have Baba's darshan and intended to remain fasting for three days. However, the chapter explains that her firm resolve was broken. She was made to prepare puranpolis and was then made to eat them to her heart's content. The implied lesson, as stated in the text, is that "Wearing out the body for others' sake - this blessed act is true welfare." By having her break her personal ascetic vow in favor of service and partaking in the food, she was taught a profound spiritual principle about true welfare that she would never forget.
