What lesson about fasting versus selfless service is presented in Chapter 32?

Chapter 32 presents a clear teaching on the relative value of fasting and selfless service through the story of a woman devotee. This woman arrived with the firm intention to fast for three days. However, Sai Baba guided her to break her fast by having her prepare and eat puranpolis. The chapter explains the profound lesson behind this act, stating, "Wearing out the body for others' sake - this blessed act is true welfare." It further reinforces this by adding, "In this lies supreme welfare." This incident, introduced in Chapter 32, serves to illustrate that while fasting may have its virtues, the act of selfless service for the benefit of others is considered a higher and more blessed form of spiritual practice.
