Can you elaborate on the story of the woman who intended to fast, as it is previewed in Chapter 32?

According to the introduction in Chapter 32, a woman came with a firm desire to have Baba's darshan and to remain fasting without food for three days. However, the chapter previews that an occasion arose which led to her firm resolve being broken. Sai Baba intervened and had her hands put to work preparing puranpolis. Not only did he have her make the sweet flatbreads, but he also made her eat them to her heart's content. The text explains that this was a blessed act of teaching her that the supreme welfare is found in 'wearing out the body for others' sake,' thus making her understand the true virtue behind practices like fasting.
