Can you tell me about the woman who wanted to fast? What was the lesson Baba taught her according to Chapter 32?

In Chapter 32, we learn of a woman who visited Shirdi with the firm intention of fasting for three days. However, Sai Baba intervened in her plan. He broke her resolve by having her prepare puranpolis and then made her eat them to her heart's content. The profound lesson embedded in this act, as the chapter explains, is that "wearing out the body for others' sake - this blessed act is true welfare." Baba demonstrated that selfless service and providing for others constituted a supreme form of welfare, more virtuous than the personal austerity of fasting, a lesson she was made to understand so she would never forget.
