What does Chapter 32 say about fasting versus selfless service based on the story of the woman and the puranpolis?

Chapter 32 presents a nuanced view on austerity through the story of a woman who resolved to fast for three days at Shirdi. Her firm resolve was intentionally broken by Sai Baba, who had her prepare and then eat puranpolis until she was content. According to the chapter, this was a lesson to help her understand a deeper principle. While the text acknowledges that fasting has virtues, the narrative emphasizes that "wearing out the body for others' sake" is a blessed act and constitutes "supreme welfare." This incident, as described in Chapter 32, was orchestrated by Baba to make her understand this lesson in a way she would never forget, suggesting that selfless service can be a higher form of spiritual practice than personal austerity.
