Can you explain the incident involving the woman who wanted to fast, as described in Chapter 32?

In Chapter 32, a woman arrives with a strong desire to have Baba's darshan and to observe a three-day fast. However, Sai Baba intervenes in her plan. The chapter details how her firm resolve was broken when she was instructed to not only make puranpolis but also to eat them to her heart's content. The underlying lesson, as highlighted in Chapter 32, is that "wearing out the body for others' sake - this blessed act is true welfare." Baba's actions were intended to make her understand the deeper meaning of service and devotion over rigid, self-imposed austerity.
